RDL - 40 W Stereo Audio Power Amplifier with Power Supply-Export Model-Excludes Power Cord

Model: TX-PA40DE MSRP: $435.23

The TX-PA40D is the ideal choice in many applications where a high quality, high-efficiency utility amplifier is needed to drive a pair of 4 Ω or 8 Ω speakers. It is specifically suited to fixed-gain amplification applications where ...gain is controlled by other equipment. Examples include projectors with variable audio outputs used in classrooms, boardrooms and video conferencing.The TX-PA40D features two unbalanced line level inputs on high-reliability gold plated phono (RCA) jacks. A front-panel recessed gain control trimmer permits setting the desired amplifier output level for each channel. The gain range accommodates the range of typical unbalanced audio signal levels. Each of the two TX-PA40D outputs will drive a 4 Ω or 8 Ω speaker or multiple speakers connected to present a 4 Ω or 8 Ω load to the amplifier. The output impedance is switch-selectable on the front panel of the module.A front-panel switch is provided to sum the audio inputs to mono. In theSTEREOmode, the TX-PA40D independently amplifies each audio channel, left (L) and right (R). If speaker placement in the specified installation is incompatible with stereophonic amplification, theINPUT MODEswitch may be set toSUMMED MONO.The TX-PA40D includes a stereo analog compressor/limiter for audio fidelity noticeably superior to conventional class D amplifiers with digital limiting. The inputGAINsettings determine whether the limiter alone is used for clipping suppression, or if the full compressor/limiter will be used to substantially increase the average output power beyond that of a standard 40 W amplifier. A red front-panel LED flashes when the limiter is preventing output clipping. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics. If the input level is increased so the compressor is active, the LED remains dimly lit between peak flashes. 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 TX-PA40D, with compression, is capable of producing average audio output levels and clarity normally expected from stereo amplifiers with a much higher output power rating.A bluePOWERLED illuminates when the TX-PA40D is powered from its external 24 Vdc power supply. The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stages produce minimal heat for all levels of expected voice or music modulation. Continuous full-power operation with audio tones will not damage the amplifier, but is not recommended.Wherever an ultra-compact, high quality, high efficiency audio power amplifier is needed to provide reliability and unsurpassed versatility, the TX-PA40D is the ideal choice. Use the TX-PA40D individually, or combine it with other RDL products as part of a complete audio/video system.

RDL - Paging Controlled Relay

Model: TX-PCR1 MSRP: $262.54

The TX-PCR1 is the ideal choice in many applications where switching needs to be controlled from a constant-voltage amplified audio source. The module will trigger on any program material, with paging sources being the most common. The TX-PCR1 i...ncludes both an open-collector SLAVE output to control other modules or equipment and a DPDT high power switching relay suited to switching speaker loads. The amplified audio source is connected using a detachable terminal block. A front-panel switch is provided to select the source type: 25 V, 70 V or 100 V. The 25 V setting may be used for an 8 ohm, 75 Watt maximum, amplified source. Input sensitivity is adjusted on a single-turn trimmer. In the clockwise position, the SENSITIVITY trigger threshold is 30 dB below the switch-selected constant voltage. A red LED illuminates whenever the audio level exceeds the trigger threshold, facilitating the sensitivity adjustment. The module is triggered when the audio exceeds the threshold and it remains triggered for a defined time duration after the audio falls below the threshold. This DELAY is adjustable from 3 to 25 seconds using a front-panel trimmer. Adjustment is simplified by a green LED that remains illuminated while the module is triggered. The SLAVE terminal may be used as either an input or output control terminal. When the module is triggered, the SLAVE terminal is internally pulled to ground through an open collector. If the TX-PCR1 SLAVE terminal is externally pulled to ground through a switch or the open-collector terminal of another RDL module, the relay will energize until the terminal is released. A blue POWER LED illuminates when the TX-PCR1 is powered from an external 24 Vdc power supply. Use the TX-PCR1 relay contacts to switch speaker lines or to control the logic inputs of other equipment with control inputs that may not be pulled up to 24 V. The TX-PCR1 is ideal to provide local speaker muting during an area page. The double pole contacts allow local speakers to be automatically connected to a paging line during a page and reconnected to the local amplifier when the page is completed. If additional speaker lines need to be switched, the SLAVE terminal may be used to control additional TX-PCR1 modules or RDL ST-LCR1H High Power Logic Controlled Relays.
