Commercial Sound Equipment

The RDL D-J1 Microphone Input Assembly is a complete microphone input panel assembly. Connections to the female front-panel XLR jack are made on a rear barrier block. The D-J1 fits directly into back boxes, available from RDL to fit cabinets or US or international walls (RDL WB-1U).

The RDL D‑CIJ3 is the ideal choice in installations requiring the passive mixing of two unbalanced line level audio sources to feed a mono balanced (or unbalanced) audio line. The D‑CIJ3 is a complete unbalanced line‑level audio input module.

The RDL D-CIJ3D Stereo Consumer Input Jacks are the ideal choice in installations requiring stereo unbalanced line level audio sources to feed stereo balanced (or unbalanced) audio lines. The D-CIJ3D is a complete unbalanced line-level audio input module.

The RDL AV-HK1 is a stereo transformer isolation module for use with unbalanced, high impedance audio inputs. Input and output connections are provided on gold-plated phono jacks. The AV-HK1 is supplied with two adapter cables to facilitate connecting with products that use mini-plugs and jacks.

The RDL ST-VCA3 Voltage Controlled Amplifier is used in applications requiring smooth audio level control from a remote control panel, potentiometer or dc voltage (0 to 10 V). Installation in series with the audio input of a power amplifier allows remote control of that amplifier's level.

The RDL DS-HA1A Format-A Stereo Headphone Amplifier is a two pair receiver and audio headphone amplifier compatible with RDL Format A twisted pair products. Each HA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack fed from a Format-A sender.

The EZ-ADA4 Stereo Audio Distribution Amplifier is a stereo audio distribution amplifier with gain adjustment and audio level metering. The input is connected through RCA jacks or a MINI jack. A front-panel knob adjusts for high or low input levels using the left and right channel LED VU meters.

The RDL ST MX2 2 Channel Audio Mixer is used in any application requiring mixing of two audio sources. A mic may be mixed with a line-level music source. Two mics may be mixed to feed the mic or line level input of a power amplifier.

The RDL EZ-MPA1 is a microphone preamplifier with front-panel volume control and audio level metering. A front-panel switch engages an audio compressor to control overloads and clipping during high level audio bursts or peaks from the microphone.

The RDL EZ-MX4ML Microphone and Stereo Line Audio Mixer is a stereo audio mixer with two mic and two line inputs. Microphones connect through balanced XLR jacks that provide phantom voltage. Both line inputs connect through RCA jacks; one also includes a MINI-jack input.

The RDL FP-MP1 Studio Quality Microphone Preamplifier is the ideal choice in most applications where mic to line preamplification is desired. Power connections are made using either the full-size barrier block terminals or a dc power jack located in one end panel.

The RDL TX-PA40D Stereo Audio Amplifier 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.

The RDL RU-PA40D Stereo Audio Amplifier 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 amplification applications where users need to adjust the gain.

The RDL RU-MLA2 is a dual channel audio preamplifier. The inputs and outputs may be connected through the front-panel XLR jacks or on the rear panel detachable terminal blocks. Each input accepts either a balanced microphone or line level signal. Each output provides either a microphone or line level signal.

The RDL TX-TPR3A is a three-pair audio receiving module compatible with RDL Format-A twisted pair products. Three outputs are provided corresponding to the three signal pairs A, B and C. The audio signal received on each pair of the RJ45 INPUT jack feeds the corresponding -10 dBV unbalanced RCA phono jack output.

The RDL PS-24AS is a 24 VDC switching power supply, North American AC plug, 500 mA, dc Plug.

The RDL PS-24KS is a 24 Vdc Switching Power Supply, North American AC Plug, 1 A, dc Plug.

The RDL Model PS-24KX is a 24 VDC Switching Power Supply, Interchangeable AC Plug, 1 A, dc Plug for FP-PA amplifiers.

The RDL D Series-J3 is a complete audio input panel assembly and may be mounted directly into cabinets or most standard US single gang electrical boxes.

The RDL TX-J2 is part of the group of versatile TX series products from Radio Design Labs. The TX series feature the advanced circuitry for which RDL products are known, combined with durable, quality connectors.

The RDL STP-1 is a pair of convenient attenuator pads that can be located at the precise location that attenuation is needed.
