Mona’s Guitar Input (1/4” Plug, Impedance: 107K, Trim:
10 – 50dB)
An input impedance of 10K is too low to record non-active guitar pickups, so each
input also has its own
GUITAR
switch. When the
GUITAR
switch is pushed in
(green indicator lit), the input impedance is increased to 107K and the trim knob
has a range of 10 to 50dB. The indicator will only light up if there is a ¼”
connector plugged into the jack. This mode will still provide a balanced input
when a TRS connector is inserted.
If you want to adjust the level of any input, just turn the knob for that input and
watch the corresponding level meter on Mona’s front panel. The red bar at the top
will light anytime the input signal is greater than –3dB (or within 3dB of clipping).
The three yellow bars each represent a range of 3dB and the green bars each
represent a range of 6dB.
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
