Design Rules

To avoid any low frequency phase errors all signal paths (apart from talk back and listen back microphone inputs) in the A-Mon are DC coupled.

To avoid cross talk any unused input is muted at the input.

The metering uses precision rectifiers to provide approximately 60 dB of range.

The NJM2068 op amp was selected for its audio performance.

Audio switching via high voltage cmos (+/-14v) with a maximum signal level of +/-8v p to p
to minimise distortion.

Gain Control on both inputs and outputs via CS3318 8 channel gain control.

Customer Comments

Toby Craig (Oxygen Sound Studios-Berlin)

I just wanted to write you.

We’ve been very impressed with the sound quality of the A-Mon, we find it far superior to the X-Mon's we have in our other studios. The noise floor is excellent for post production work and we find out mixes have even more clarity as a result. Additional features such as the surround channel order and 7.1 muting capability make it an excellent replacement for the X-Mon.

I hope that doesn’t sound too much like advertising, but it’s the truth.
