Front Panel connections
Instrument Inputs
The ¼” jacks on the front panel serve as an instrument input. The input impedance is always >1M
Ohm and the gain can be adjusted by the Input gain control. The maximum input signal level is
+17dBu (5Vrms) @ minimum input gain.
When you plug into this jack it DISABLES the balanced input on the rear of the unit. This feature
allows you to keep the rear input patched in, and use the instrument input to switch to a different
source. The instrument input allows the DIGITAL MPA II to serve as a great DI device as well.
