Turning the Power On/O
Once everything is properly connected (p. 4, p. 5), be sure to
follow the procedure below to turn on their power. If you turn on
equipment in the wrong order, you risk causing malfunction or
equipment failure.
1. Make sure that the power to all equipment is turned o.
2. Set each of the AC-40’s [VOLUME] knobs and the
[MASTER] knob to 0.
3. Switch on the power to any external equipment
connected to the AUX IN jack.
4. Switch on the AC-40’s power.
* This unit is equipped with a protection circuit. A brief interval (a
few seconds) after turning the unit on is required before it will
operate normally.
5. Switch on any equipment connected to the LINE OUT
jacks.
6. When you want to turn the power o, minimize the
volume on the AC-40 and all connected devices, and then
turn o their power in the opposite order of that followed
when turning them on.
* Before turning the unit on/o, always be sure to turn the volume
down. Even with the volume turned down, you might hear some
sound when switching the unit on/o. However, this is normal
and does not indicate a malfunction.
Using Eects
Chorus and reverb are provided for both the Guitar channel and the
Mic/Line channel.
You can adjust the eect depth individually for each channel.
Applying Chorus
1. Set each channel’s [CHORUS] switch to “WIDE” or “SPACE”
position.
WIDE
This is a stereo chorus that processes the three bands
independently.
By applying band-appropriate chorusing to each of the low,
mid, and high-frequency bands, this eect creates a deep and
spacious chorusing that is appropriate for the sound of an
acoustic guitar.
The low range remains rmly localized in the center, and the
sound will become more spacious as you go from the mid to
the high range.
SPACE
This is a chorus that mixes the sounds in the air, a method that
is possible only with a stereo system. On the AC-40, the eect
sound is emitted by the right speaker (as you face the unit),
and the direct sound is emitted by the left speaker. The chorus
eect is produced as the sound from the left and right speakers
is mixed in the air.
Compared to an electrically mixed chorus eect, this eect
has a broader left/right spread and a more natural-sounding
spaciousness.
OFF No chorus eect will be applied.
* If the [CHORUS] switch is “OFF,” you won’t be able to turn chorus
on/o by operating the footswitch.
Applying Reverb
This is a stereo reverb that was developed specically for acoustic
instruments and produces a spacious and natural sound.
1. Use the [REVERB] knob to adjust the depth.
* If the [REVERB] knob is at 0, you won’t be able to turn reverb on/
o by operating the footswitch.
