3. EFFECTS LOOP jack (AC30C2(X)/AC30CH)
NOTE! Be sure to use shielded guitar cables only! NEVER use unshielded speaker cables.
4. FOOT SWITCH jack
5. MAINS INPUT connector
6. Attenuator (AC30CH/AC15CH)
NOTE! When the IMPEDANCE Switch is set to 8Ohms the attenuator does not work.
What is a Reactive Attenuator?
Our Reactive Attenuator design allows for a truer tone even at attenuated output volumes. This is
achieved by using our proprietary Reactor technology to allow the speaker and the amplifier interact
with one another, even with a resistive load (the attenuator) in line. This means the amplifier and
speaker behave the same way as a non-attenuated amplifier, with resonant peaks and troughs. What
this simply means to you is great tone, without the volume.
1) Set it to this if you connect an extension cabinet through the Extension jack.
You'll be running the internal and external speakers in parallel. The impedance of
the extension cabinet must be 16 Ohms.
2) Set it to this if you connect an external 8 Ohm speaker cabinet through the
External jack.
HEAD
1) Set it to this if you connect two external 16 Ohm speaker cabinets.
2) Set it to this if you connect an external 8 Ohm speaker cabinet through the
LOUDSPEAKER jack.
The EFFECTS LOOP allows effects to be added further down the signal chain,
rather than just plugging them in line with your guitar and amplifier. By using the
Effects loop with Delay stomp boxes, for example, will prevent any strange distor-
tions to the time delayed repetitions.
Please note that the EFFECTS LOOP sends at -10dB meaning it is suitable for
stomp boxes.
BYPASS ON/OFF: This is a true bypass effects loop which means if this is set in the
"BYPASS" position, absolutely none of your original signal will be running through
until it's switched "ON".
RETURN: Think of this as the "input" of the effects loop and will be connected to
the output of your effect(s).
SEND: Think of this as the "output" of the FX loop and will be connected to the
input of your effect(s).
This is where you connect the Optional VFS2A Foot Switch so you can turn the
REVERB and TREMOLO on and off.
This is where the supplied, detachable Mains (power) cord is connected. The specific
mains input voltage rating that your amplifier needs to run at is located on the rear panel
of your amplifier. Before making any connections or powering up the amplifier, make sure
the correct voltage is set. If you have any doubt, refer to your local VOX dealer.
The AC30CH/AC15CH has a built in Reactive Attenuator. This enables you to keep the
great sounds of a driven AC30CH/AC15CH at more ear friendly volumes.
AC30CH
There are 3 settings, 30W (BYPASS), 3W (-10dB Attenuation) and 1/3W (-20dB Attenuation).
AC15CH
There are 3 settings, 15W (Bypass), 1.5W (-10dB Attenuation) and 1/6W (-20dB Attenuation).
