Audio Delay



The Advanced Repeater Systems Audio Delay Board eliminates repeated audio squelch tails using high-performance digital technology.

The ARS Audio Delay Board has high-isolation audio gates controlled by an active high or active low COS.  Delay time and audio level are easily set with potentiometers. 

The Audio Delay Board can be used as a Standalone Repeater Audio Gate or with any Repeater Controller to enhance the sound of your repeater.

Below is an Audio Delay Board mounted on a Motorola Micor Repeater Audio/Squelch Board.  Here, the Audio Delay Board is the Repeater Audio Gate controlled by the active-low COS signal (the board has both an active high and an active low input, but only one is typically used and the other is left open).  Although the Micor has a dual mode fast/slow squelch circuit, the Audio Delay Board completely eliminates the squelch tails; greatly improving the repeater's sound and the user's experience. 


Installation is simple with five connections: Power, Ground, Audio In, Audio Out and COS (or CTCSS).

It is available with solder pads for wires (shown above), a 90 degree low profile connector or a straight pin connector.
