Rear Panel
15 Mains Connector (AC Power Inlet; IEC - C14 connector)
Plug the mains cord in here. For European models, use a standard non-heating equipment
connector cable.
CAUTION: Make sure you use an intact mains line cord with a grounded plug!
Before you power the amp up, ensure the voltage value printed on the label next to
the mains socket is the same as the current of the local power supply or wall outlet.
Please also heed the guidelines set forth in the separately included pamphlet,
Instructions for the Prevention of Fire, Electrical Shock and Injury.
16 Mains Fuse Box: The rear chamber contains the mains fuse and in the front chamber, a spare fuse.
CAUTION: ALWAYS make sure replacement fuses are of the same type and have the same ratings
as the original fuse! Please refer to the fuse ratings table.
17 Footswitch Reverb; FX Loop off/on:
Use this ¼" Stereo jack to connect a conventional footswitch
with two switching functions, for example, the ENGL Z-4 (2 x off/on - Single Pole Single Throw or
SPST for short). This type of footswitch lets you switch
Reverb off or on and FX Loop off or on.
One of the two switches engages the internal Reverb the other enables or bypasses FX Loop.
The Reverb system and the FX Loop are activated by default if you do not connect a footswitch
to this jack. Note also that a footswitch may be equipped with LEDs indicating the given switching
status. Each of the two switches is provided with about 10 milliamperes of current, which suffices
to power a standard LED. The jack's mono terminal (the tip) switches the
Reverb off or on,
and the stereo terminal (the ring) switches FX Loop off and on.
For pin assignments, see "Wiring of Principal Connectors".
18 Footswitch Clean/Lead; Mid Shape (Mid Boost oder Mid Scoop): Use this ¼" Stereo jack to
connect a conventional footswitch with two switching functions, for example, the ENGL Z-4
(2 x off/on - Single Pole Single Throw or SPST for short). This type of footswitch lets you access the
two channels and
Mid Shape (collective term for Mid Boost and Mid Scoop).
One of the two switches activates Clean or Lead; the other controls the Mid Shape function
Mid Boost, RockMaster amp: boosts a certain mid frequency range when activated;
Mid Scoop, MetalMaster amp: cuts ta certain mid frequency range when activated;
Plugging a footswitch into this jack disables onboard channel (10) and Mid Shape (9) switching.
Note also that a footswitch may be equipped with LEDs indicating the given switching status.
Each of the two switches is provided with about 10 milliamperes current, which suffices to power
a standard LED. The jack's mono terminal (the tip) selects Clean or Lead, while the stereo terminal
(the ring) switches
Mid Shape . For pin assignments, see "Wiring of Principal Connectors".
A Tip from the designer: If you want to control the amplifier via a MIDI system, use jacks 17, 18
and a looper or MIDI switcher (such as the ENGL Z11-S.A.C). Use two stereo ¼" cords to connect
the optionally available ENGL MIDI Switcher Z11-S.A.C.. You can then preset the four switching
functions
Clean/Lead , Mid Shape , Reverb off/on and FX Loop off/on via the switcher, store your
custom switching setups as different MIDI programs, and activate the presets via a MIDI board
such as the ENGL Z-12. For more details, see the remote control options on the last page.
19 FX Loop Send: Connect the serial FX Loop output to a signal processor's input/return jack using
the shortest possible shielded cord equipped with 1/4" plugs. The FX Loop can be controlled
remotely (on/off function) via a footswitch connected to jack 17 (for details refer to chapter 17).
In the signal path, the FX Loop is located post preamp and pre the power amp Master knob.
20 FX Loop Return: Connect the FX Loop input to a signal processor's output/send jack using the
shortest possible shielded cord equipped with 1/4" plugs. The FX Loop can be controlled remotely
(on/off function) via a footswitch connected to jack 17 (for details refer to chapter 17).
In the signal path, the FX Loop is located post preamp and pre the power amp Master knob.
Note: Inserting a ¼" jack plug into the Return port interrupts the circuit between the preamp
and power amp.
