Using the Mic Input
The AC75 and AC150 Acoustic Ribbon amplifiers offer
a microphone input that you can use for mic'ing your
acoustic instrument, or for connecting a microphone
level signal from an acoustic pre amp like the Hartke
Acoustic Attack pedal. You can also use the MIC input
to connect a standard low impedance vocal micro-
phone. Plus, the Mic input feature Phantom power for
using condenser microphones. The Acoustic Ribbon
series amplifiers actually make a great vocal monitor
thanks to the flat and natural response of its built-in
speaker system.
• If you want to connect a microphone, first start by
turning the main VOLUME all the way down. Use a
low impedance mic and make the connection with
a standard XLR mic cable to the to the Channel 2
XLR mic input located on the front panel.
• Next, raise the main VOLUME to about "6 -7" (or the
1 -to 3 o'clock position).
• Now, slowly raise the GAIN until you add the
desired amount of Mic level with your acoustic.
Keep in mind that you may need to adjust the
Channel 1 and Channel 2 GAIN controls to get the
best blend between the mic connected to Channel
2 and the instrument connected to Channel 1.
• To add the EFX to the MIC input, engage the EFX
ON/OFF switch on Channel 2. The red EFX LED will
illuminate when the EFX are engaged.
