1) INPUT CH1 Connect your acoustic instrument to this input using a standard ¼” shielded instrument cable.
2) CH1 GAIN This controls how much signal is passed through the CH1 preamp stage of the unit, which includes equalization and the effects
loop.
3) CH1 CLIP LED If playing through the amp causes the blue CLIP light to turn on at all, you should turn down the GAIN control to set the
optimal gain level for your instrument’s signal.
4) CH1 LOW This knob controls the amount of low frequencies in your sound, boosts or cuts the level of the frequencies around 40 Hz (± 16
dB).
5) CH1 MID This knob controls the level of mid frequencies, boosts or cuts the level of the frequencies around 600 Hz (± 16 dB).
6) CH1 HIGH This knob controls the level of high frequencies, boosts or cuts the level of the frequencies around 6 KHz (± 16 dB).
7) CH1 EFFECT MIX Controls the amount of effect in the channel 1.
8) EFFECTS) The DV AC101 features last generation of digital reverb and chorus effects, they are sweet-sounding, warm and natural. The
selected effect is common for CH1 and CH2, thanks to the separate Effect MIX (7-15) you can regulate the amount of effect for each channel.
9) PHASE SWITCH The Phase switch flips the polarity of your instrument signal from positive to negative, changing its relationship to the
sound coming from the amplifier. Use the Phase switch in conjunction with the Anti-Feedback control knob to eliminate acoustic feedback.
10) ANTIFEEDBACK The Antifeedback knob control is a variable frequency notch
filter designed to isolate and eliminate feedback. Turning the knob adjusts the center frequency of the filter, ranging from 20Hz (off) to 400Hz
at full clockwise.
11) INPUT CH2 This input accepts either a balanced XLR signal (for microphone or in case your intrument’s pickup supplies a balanced
output) or an unbalanced signal using a standard ¼” shielded instrument cable.
12) GAIN CH2 This controls how much signal is passed through the CH2 preamp stage of the unit, which includes equalization and the
effects loop. In case of condenser microphone or pickup system with phantom power, pull out the CH2 GAIN knob to engage 48V phantom
power on balanced XLR input.
13) CH2 CLIP LED If playing through the amp causes the blue CLIP light to turn on at all, you should turn down the GAIN control to set the
optimal gain level for your instrument’s signal.
