Radio Design Labs (RDL)

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 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 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 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 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 EZ-HDA4B Stereo Headphone Distribution Amplifier contains four stereo headphone amplifiers with individual front-panel volume controls. Headphone outputs are provided on rear-panel MINI jacks.

The RDL EZ-HSX4 Stereo Audio Input Switcher with Headphone Amp is a stereo audio source selector with an output volume control. Line-level and headphone outputs are provided. This unit is ideal as a four input headphone amplifier and as a source selector feeding an associated audio amplifier.

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 DB-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 TX-LC2 is the ideal choice in installations requiring the active, isolated mixing of two unbalanced line-level audio sources to feed a balanced (or unbalanced) audio line.

The RDL EZ-MX4L Stereo Line Level Audio Mixer is a stereo audio mixer with four line inputs. All line inputs connect through RCA jacks; one also includes a MINI-jack input. Left and right channel LED VU metering facilitates easy level adjustment.

The EZ-HK1 is a superior-quality stereo audio transformer isolation module for use with unbalanced, high impedance audio inputs. Input and output connections are provided on gold-plated RCA jacks.

The EZ-AFC2 is a stereo bi-directional audio format converter with level controls. Conversion is provided between balanced rear-panel XLR jacks and unbalanced front-panel RCA jacks.
