Description:
This simple setup allows the audio from a computer or other audio source to be shared with the audio system in another room. In this example the audio is fed from the computer into a wall plate that is wired directly to a wall plate in the second room. The two wall plates are connected with two balanced shielded audio cables. These wall plates are avaliable in RDL’s grey/white color or in stainless steel. Custom labeling is available.

Description:
This application illustrates how to interface a turntable with common audio equipment not equipped with phono inputs. The EZ‑PH1 is a compact phono preamp that produces an unbalanced stereo output using the RIAA equalization curve. Input and output connections are made through gold‑plated RCA jacks for easy connection to an amplifier auxiliary input or a CD recorder line input. Gain trimmers for each channel and dual‑LED VU meters make it easy to set preamp levels. The EZ‑PH1 is the ideal solution for phonograph record playback or dubbing. A grounding screw is provided for connection to the tone arms of quality turntables.

The EZ‑PH1 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
Many inexpensive unbalanced audio switches use mechanical contacts to switch the audio. This leads to switch noise and unreliable operation, particularly after the switches have been in service for several months. The RDL EZ‑SX4 provides long‑life, silent switching by using solid‑state technology for all audio switching. The EZ‑SX4 allows the user to select one of four unbalanced stereo sources. The output feeds the power amplifier driving the stereo speakers. The EZ‑SX4 output level is adjustable using a front‑panel knob, allowing a user to select a source and adjust volume from one location.

The EZ‑SX4 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
The EZ‑HSX4 has an integrated headphone amplifier that adds versatility to the four input stereo switcher. The EZ‑HSX4 uses solid‑state switching to insure reliability and so that mechanical switch noise does not affect signal quality. The front‑panel headphone jack monitors the line‑level output which may be used to feed sound systems in different rooms or to feed recording equipment. If the line output is not used, the EZ‑HSX4 can serve as a headphone amlifier with four switched inputs. The line‑level stereo output can be switched to unity (fixed) gain or can follow the level set by the front‑panel volume knob that adjusts the headphone output level.

The EZ‑HSX4 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
The EZ‑MXA20 is a feature‑rich mixer amplifier. In addition to two stereo line level inputs, the mixing section of the EZ‑MXA20 features a high quality mic preamplifier with switch‑selectable phantom power. Output power is 10 Watts RMS per channel into 8 Ohm speakers (8 Watts RMS per channel for 4 Ohm speakers). The power amplifier features a compressor, with a front‑panel LED indicator, to protect against clipping. The front panel also features a two band equalizer for tailoring frequency response. The compact size of the EZ‑MXA20 makes it the ideal choice when there is limited space for a full‑featured mixer amplifier.

The EZ‑MXA20 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
It is frequently necessary to use professional and consumer audio equipment in the same environment. The EZ‑AFC2 provides both balanced‑to‑unbalanced and unbalanced‑to‑balanced conversion for stereo audio line‑level signals. Superior electrical performance ensures audio transparency. All channels are monitored via dual‑LED VU meters. Front panel knobs allow for easy level adjustment. The fully connectorized EZ‑AFC2 makes this common interface task as easy as possible.

The EZ‑AFC2 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
Switching between multiple A/V sources is a common task in home theatres. This diagram illustrates the EZ‑AVX4 being used to switch between a DVR, DVD player, a gaming console and a VCR. The RDL EZ‑AVX4 Composite Video and Stereo Audio Input Switcher features solid state switching on the audio and video signals making them immune to mechanical switch noise and ensures a long life of reliable operation.

The EZ‑AVX4 is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
This application demonstrates how to distribute a composite video signal to a remote location in a house. The EZ‑VDA2R’s bandwidth is > 400 MHz which ensures a high quality picture. Gain and equalization controls on the front panel allow adjustments for long cable runs. The EZ‑VDA2R provides professional performance in a very compact package.

The EZ‑VDA2R is shipped with a high efficiency power supply that connects to a locking dc power jack.

Description:
An outdoor patio is equipped with a DS‑CIJ3 Consumer Input Jack Decora® plate that provides connectivity for an MP3 music player or other stereo audio source. The DS‑CIJ3 provides a balanced mono sum of the MP3 player source to the ST‑PA18 Audio Power Amplifier. The ST‑PA18 is a high‑efficiency, Class D power amplifier that provides 18 Watts RMS to the rock speakers. The ST‑PA18 has an integral audio compressor to control clipping. The DS‑CIJ3 (mounted in a CP‑1S Stainless Steel Single Gang Cover Plate and SMB‑1G Surface Mount Box) and the ST‑PA18 are mounted in a standard weatherproof box.

Description:
A stereo unbalanced audio signal from a home entertainment system is summed and converted to a balanced mono signal using the TX‑J2 Unbalanced Input Transformer. An RDL FP‑PA20A 20 Watt 70 Volt Audio Power Amplifier powers four 70 Volt outdoor rock speakers in a patio seating area. Each speaker is tapped at 5 Watts, for a total of 20 Watts. The volume is controlled by the home entertainment system. Using a 70 Volt system allows for the use of smaller cable sizes which reduce system costs and simplify the installation. An RDL FP‑PA20B 20 Watt 25 Volt Audio Power Amplifier may be used in place of the FP‑PA20A if a 25 Volt system is desired.
