Specifications
Design Rules
-  To avoid any low frequency phase errors and capacitor distortion almost all signal paths in the I-Mon are DC coupled. The only exceptions are the talk back and listen back microphone inputs.
- Bass Extension Low pass filter uses Low distortion Polyphenylene Sulphide Film Capacitors
- To avoid cross talk any unused inputs are muted at the input
- DC Coupled metering with precision rectifiers to provide approximately 60 dB of range
- The NJM2068 op amp was selected for its audio performance.
- To minimise distortion audio switching via high voltage cmos (+/-14v) with a maximum signal level of +/-8v p to p

Gain Control via CS3318 gain control chip with muting and zero crossing switching for click
free input/output selection, mutes and gain control.
