- Page 2 Overview: The “Audio-Pod System with IFB Receive” is a microprocessor controlled Microphone On-Off control system with an integrated headphone amplifier and IFB Receive capabilities which is ideal for remote and talk studio applications. The Mic ON/OFF buttons may be top or front mounted depending on the application. The latching Microphone On-Off circuitry incorporates a high quality, low noise pre-amplifier with available switched 48VDC phantom power.

IMPORTANT: Maintain SSR output polarity considerations between the Audio-Pods or damage may result. If multiple Audio-Pod SSR outputs are used for driving a single LED indicator, a 220 ohm series resistor between the positive outputs and the LED is recommended.
