Hartke ACOUSTIC RIBBON AC75 Mode D'emploi page 14

Setting Up and Using Your Hartke AC75 and
AC150 Acoustic Amplifier
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.
