RDL - Format-A Twisted Pair Remote Controlled Mixer

Model: FP-TPX3A MSRP: $618.45

The FP-TPX3A is the ideal choice where a user-accessible mixer must control the volume of multiple sources in a zone. RDL Format-A twisted pair audio senders connect directly to the mixer, allowing each user input to be balanced or unbalanced, m...ic or line level. FP TPX3A outputs are provided in balanced and unbalanced formats. Two unbalanced outputs are available to feed the mono mixer output to a stereo amplifier input. Remote control of the mixer allows audio signals to be kept at a single equipment location. Audio is mixed by VCA circuits that are adjusted by control signals from the remote control. Two Format-A jacks are provided for signal inputs. If the Format-A senders are daisy-chained, only one of the input jacks is used. Two jacks are provided so that two home runs from Format-A senders are possible. The FP-TPX3A provides power to all connected active senders. The FP-TPX3A is designed to mix the three Format-A audio signals from pairs A, B and C. A detachable terminal block allows a LOCAL INPUT to be connected directly to pair C. This input may be used if no connected sender is set to use pair C. The terminal block is included so a local paging or music source can be connected if pair C would not otherwise be used. Each INPUT GAIN control is calibrated to be adjusted clockwise for an unbalanced passive sender; counter-clockwise for an active sender or passive sender with a balanced input. A standard RDL dual-LED VU meter provides visual indication of the output level from the mixer. The mixer output is mono. The output is available on a single balanced detachable terminal block or on two unbalanced RCA jacks intended to connect directly to the stereo input of a power amplifier. The AUDIO LED illuminates whenever audio is present at the output of the mixer, defined as greater than 35 dB below +4 dBu. This threshold triggers the AUDIO DETECT OUTPUTS. Two open collectors are provided on a detachable terminal block. One of these terminals switches low when audio is present, and may be used to switch amplifiers or other system components on. The other terminal is pulled low when audio is not present. It is intended for muting the digital carrier of power amplifiers equipped for remote muting. Either of these terminals may be used to trigger a variety of other RDL modules or OEM equipment. The use of these terminals to shut down unused equipment can produce effective system energy and cost savings. These control terminals normally remain triggered for 10 minutes after audio is absent. The delay can be increased to 20 minutes using a ground jumper on the terminal block. The mixer levels are set by RDL remote controls that connect directly to the FP-TPX3A through an RJ45 jack using standard twisted pair cable. The control ports on the mixer and remote controls are color-coded light blue to distinguish them from standard Format-A jacks. The mixer provides power to the remote control. Either a two or three channel remote control may be used. If remote mixing of only two channels is needed, a two channel remote may be used. Pair C becomes the input channel that is not remotely controlled. The PAIR C/LOCAL INPUT can be left active at unity gain, typically for a paging source, or may be disabled by a switch set during installation. If the cable connected to the remote control becomes disconnected, the mixer output mutes.

RDL - 35 Watt Mixer Amplifier-25 V, 70 V, 100 V Outputs

Model: HD-MA35A MSRP: $533.70

The HD-MA35A is a three input audio mixer amplifier for systems demanding a broad range of features and high energy efficiency. Two output power amplifier zones are provided, 35 W (Zone 1) and 2 W (Zone 2). The Zone 1 output is driven from a hig...h-efficiency Class D amplifier stage. The Zone 1 amplifier output level may be VCA controlled using various optional RDL remote controls, or by industry standard 0 to 10 Vdc or 0 to 10 kOhm controls. This output provides a constant voltage (25 V, 70 V or 100 V). The Zone 2 amplifier output drives an 8 Ohm speaker and/or 600 Ohm telephone equipment. The HD-MA35A is engineered and manufactured in the U.S.A. The HD-MA35A features two mixers. The Zone 1 mixer is located on the front-panel providing user level and tone controls for the 35 W amplifier output. The tone controls adjust the equalization at the Zone 1 amplifier output. The Zone 2 mixer on the rear panel provides level trimmers normally set by the installer to provide music-on-hold and/or for background music in a small zone equipped with an 8 Ohm speaker. The Zone 2 section includes a 2 W amplifier and a 600 Ohm transformer-balanced MOH output. The HD-MA35A has three inputs that are common to both mixers. Input 1 accepts a balanced mic or line level source. Inputs 2 and 3 accept unbalanced mono or stereo line-level sources. Input 1 is switch-selectable MIC or LINE. Phantom voltage (IEC standard 24 Vdc) is switch-selectable for the microphone input. The line input is transformer isolated and accepts balanced or unbalanced, high or low impedance audio sources. A paging source is normally connected to Input 1. This input is equipped with push-to-talk terminals and with an adjustable threshold VOX circuit with LED threshold indicator, either (or both) of which may be set to duck ("fade down" or "mute") inputs 2 and/or 3 by 25 dB when a paging signal is active on Input 1. The attenuated inputs fade up to normal volume when the paging message is finished. Inputs 2 and 3 each provide unbalanced stereo RCA input jacks, summed to mono. The HD-MA35A is equipped with a master VCA for remote adjustment of the Zone 1 amplifier output. A detachable terminal block is provided for direct connection of an optional RDL remote level control. A balanced line-level output is provided on a detachable terminal block to feed the inputs of other audio equipment or power amplifiers. Ground-referenced 24 Vdc power is available on a rear-panel terminal block to power an optional external RDL module which may be mounted on the panel space provided. External module type examples: audio filtering or processing, mixing, isolation, twisted-pair sender/receiver. The Zone 1 amplifier includes an analog compressor/limiter for audio fidelity noticeably superior to conventional class D amplifiers with digital limiting. Increasing the input gain can substantially increase the average output power beyond that of a standard 35 W amplifier. A red front-panel LED flashes when the compressor is preventing output clipping. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics. The audio is compressed according to three dynamic time constants providing aural transparency while maintaining clean, unclipped amplified audio for input overloads of up to 20 dB. The HD-MA35A, with compression, is capable of producing average audio output levels and clarity normally expected from amplifiers with a much higher output power rating.

Product Features:

Three inputs with individual front-panel volume controls
Bass and Treble tone controls
Designed for background music with paging and music-on-hold

Model: HD-PA35UA MSRP: $451.77

The HD-PA35UA is a single input audio amplifier for systems demanding the highest energy efficiency. It may be used as a single zone amplifier fed from a variety of RDL or OEM mixers. It is ideal for providing one or more additional zones to a m...ix originating from another RDL HD series mixer amplifier. The 35 watt power amplifier output is driven from a high-efficiency Class D amplifier stage. The amplifier normally shuts down (standby "sleep" mode) when audio is absent and automatically turns on when needed. The amplifier output level may be VCA controlled using various optional RDL remote controls, or by industry standard 0 to 10 Vdc or 0 to 10k ohm controls. The amplifier provides a constant voltage output (25 V, 70 V or 100 V). The HD-PA35UA is engineered, tested and manufactured in the U.S.A. to strict energy conservation standards. The unit consumes less than 1 watt of mains power in standby mode, and meets power amplifier efficiency specifications with an analog-filtered Class-D digital output stage. The HD-PA35UA provides a front-panel control to set the input gain. An optional remote control connected to the rear-panel RJ45 jack provides for remote adjustment of the output level. The tone controls adjust the equalization at the amplifier output. The presence of a signal at the input causes the HD-PA35UA to fully turn on, activating the power amplifier and all associated equalization and compressor circuitry. When an input signal is absent, a delay timer is initiated. Rear-panel DIP switches are provided to set the power-down delay timer to a value between 10 minutes and 2 hours in 10 minute increments. After the time-out period, the HD-PA35UA enters the sleep mode until an input signal is received. The switches may be set to disable the sleep mode for systems specifying continuous amplifier operation. The amplifier includes an analog compressor/limiter for audio fidelity noticeably superior to conventional class D amplifiers with digital limiting. Increasing the input gain can substantially increase the average output power beyond that of a standard 35 watt amplifier. A red front-panel LED flashes when the compressor is preventing output clipping. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics. The audio is compressed according to three dynamic time constants providing aural transparency while maintaining clean, unclipped amplified audio for input overloads of up to 20 dB. The HD-PA35UA, with compression, is capable of producing average audio output levels and clarity normally expected from amplifiers with a much higher output power rating. During power-up and power-down, the amplifier output is protected against clicks, pops and thumping by internal soft-start solid-state switches. A blue POWER LED illuminates when the HD-PA35UA is powered from its external 24 Vdc power supply (included). The power LED is dim when the amplifier is in the standby mode, and is bright when the amplifier is fully active. A front-panel pushbutton is provided to manually cycle between standby and active modes. The power amplifier is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for all levels of expected voice or music modulation.

The RU-LB4 modules are Dante audio network interface products compatible with line-level audio equipment inputs and outputs. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in ...commercial/industrial installations.APPLICATION: The RU-LB4 is a high quality converter that provides professional line-level outputs from four Dante network received audio channels. It also converts four professional or consumer line-level sources to Dante network audio channels. Network to Line Level Interface Section The RU-LB4 converts four Dante audio channels to balanced line level. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. The professional output directly interfaces with other professional and commercial equipment without the need for additional gain. Crosstalk is below the noise floor between all outputs across the entire audio spectrum. The noise floor is better than 80 dB below operating level.One front-panel green signal LED corresponds to each of the four Dante input channels. Received audio level is indicated on the variable-intensity LED indicator, facilitating setup when a networked computer is not connected at the module's location. Line Level to Network Interface Section The RU-LB4 converts four line-level audio sources to Dante networked digital audio channels. Each input is equipped with a front-panel gain trimmer and associated Dual-LED VU meter to facilitate optimal input gain adjustment. Each input supports the complete range of normal unbalanced -10 dBV and balanced +4 dBu line-level sources. Input gain adjusted according to the Dual-LED VU meter assures an operating level that preserves full headroom with the lowest noise floor.The RU-LB4 is powered from an external 24 Vdc power supply, available separately.

RDL - Digitally Controlled 2 Channel Audio Attenuator

Model: RU-VCA2A MSRP: $600.01

The RU-VCA2A is a full-featured studio-quality dual-channel audio attenuator module for local and/or remote control of balanced or unbalanced line-level sources. Each module can be remote controlled from a single or multiple locations. Rear-pane...l terminals provide flexible control options using a variety of RDL remote controls or OEM equipment. Audio levels are controlled in 0.5 dB steps using noiseless zero-crossing digital attenuators for optimum reliability, precise tracking and long-term click-free service. Exceptional wide-band low-noise performance makes the RU VCA2A suited to level adjustment in the most demanding applications. Rear-panel inputs and outputs may each be wired balanced or unbalanced. The RU-VCA2A powers up in one of two operating modes set by a rear-panel switch. MOM (momentary) Mode In the MOM (momentary) mode, audio level is controlled by momentary pushbuttons or pulses. Remote terminals and front-panel pushbuttons are provided for up and down ramping control. If either button is held in, the audio will ramp automatically. If a button is pulsed (< 0.5 second), the audio will increment one step. The time of both the UP and DOWN ramps is individually adjustable on the front panel. Pushing remote UP and DOWN buttons simultaneously, or pressing the front-panel GO TO PRESET button, returns the audio to a preset level. The preset level is stored by adjusting the desired level using the UP and DOWN buttons, then pressing and holding the front-panel PRESET button for 3 seconds. A rear-panel switch sets the audio power-up level to either the preset level or the last level setting used. Multiple remote control locations are possible in the MOM mode. External control pulses may be either of positive polarity or pulled-to-ground (open-collector). 0 to 10 VDC Mode In the 0 to 10 VDC mode the preset function is disabled and the audio level is controlled by a remote 10 kΩ linear taper pot or by 0 to 10 Vdc. A single remote control location is possible using a remote 10 kΩ pot. In both operating modes, two separate 0 to 10 Vdc outputs are provided. The linear RAMP output drives the level display on RDL remote controls; the EQ RAMP output is used to control an automatic RDL Loudness Equalizer (see ST LEQ1). A front-panel 10-LED string display indicates the relative audio level. Control expansion is possible using the EXTERNAL CONTROL DATA jacks. One module can be set as a MASTER module to control the level of one or more additional RU-VCA2A or RU VCA6A modules set to the SLAVE mode. Use the RU-VCA2A individually, or combine it with other RDL products as part of a complete system.
