Mona’s Line Input (1/4” TRS, Impedance: 10K, Trim: 0 –

40dB)

When a ¼” connector is plugged into Mona’s universal input jack, the microphone

preamp is disconnected and a line input amplifier is inserted in its place. If the

GUITAR switch is out, the line input provides a balanced connection (for TRS

plugs) and the trim knob has a range of 0 to 40dB. The input impedance for line-

level signals is 10K. Full-scale input is 22dBu with the trim set to zero.

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.
