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.

Inputs:

• 10 kOhm balanced or unbalanced
• Input trim: -10dB to +20dB 1dB steps
• Maximum Input Level: +24 dBu @ unity gain

Outputs:

• 100 Ohm balanced or 50 Ohm unbalanced
• Balanced:+4 dBu nominal, Unbalanced:6 dB below balanced line level
• Maximum Output Level:+24 dBu
• Output Trim : -4 to +4 dB in 0.5dB steps
• Frequency Response:10 Hz to 100 kHz (± 0.05 dB)
