Audio connections – Mona

For optimal audio quality, you should adjust the input trim (knob) so that your

loudest recorded signal lights up some of the yellow bars, but not the red. If the

signal level ever exceeds 0dB the signal will be “clipped” and you will hear a

“pop” or “tick” in the recording. This is a very bad thing, and clipping should be

avoided at all costs! Mona has enough headroom so that you can be conservative

in this area and there is no need to push the input levels right up to the edge of

clipping.

Mona’s front panel also has a ¼” headphone output jack with a corresponding

volume knob which monitors analog outputs 1 and 2.

Each of Mona’s 6 outputs has one RCA and one XLR connector for your

convenience. The RCA jack outputs a –10 dBV (unbalanced) signal, while the

XLR jack outputs a +4 dBu (balanced) signal. Both connectors are active at all

times, so the output signal will always go out of both jacks.

The Computer Connector

Next to the analog inputs and outputs is a connector labeled COMPUTER. This

connector is known as a DB-9, and is similar to the serial port on a PC. It is the

point at which the audio interface connects to the Mona PCI card inside your

computer.

A cable was supplied with your Mona for this purpose. This custom made cable is

manufactured to certain specifications; if you need to replace it, you should only

use a replacement cable from Echo.
