7 MIDDLE
*MCH 1; Mid-range voicing control for the Main Channel 1 (Clean and Crunch 1).
Tip:
(see section 6, Tip!)
8 TREBLE
*MCH 1; Upper range voicing control for the Main Channel 1 (Clean and Crunch 1).
Tip:
(see section 6, Tip!)
9 TREBLE BALANCE
*MCH 1; Treble balance control, operable in the Crunch 1 channel only. This control allows you to boost
or cut the high end in relation to the amount of treble determined by the Treble (8) -setting. Activate this
control by means of the Treble Balance Active (10) pushbutton.
Tip:
If you have dialled in a very bright Clean sound (Treble control at the 3 o'clock position or higher),you
may want to reduce the amount of treble for the Crunch 1 channel to avoid a shrill Crunch sound.
This
feature can also be helpful in avoiding unintentional feedback between the speaker and the guitar.
10 TREBLE BALANCE ACTIVE
*MCH 1; This pushbutton activates the Treble Balance (9) control in the On position (pushed in).
Tip:
If you want the treble response to be identical in both the Crunch 1 and the Clean channels,
leave this pushbutton in the Off position; now the Treble Balance (9) control is inactive. Also use this
setting if you prefer to adjust the treble via your guitar's tone control.
11 REVERB
*MCH 1; Reverb control, adjusts the portion of the reverb signal and increases reverb intensity in the
main channel 1 when you rotate it clockwise; the reverb can be switched on via the Reverb Active (22)
pushbutton. The red LED above this pushbutton indicates the reverb is active. The reverb can also be
switched via the MIDI Interface Port (45), or the footswitch jack (49).
12 CLEAN VOLUME
*MCH 1; Volume control for the Clean channel. (in front of the FX loop, affects the Send level)
13 CLEAN/CRUNCH 1
*MCH 1; Channel selector pushbutton for switching between Clean and Crunch 1 modes. Off position: the
Clean channel is active; On position (pushed in): the Crunch 1 channel is active when the main channel
selector pushbutton (39) is in the Off position (Main Channel 1) in both cases. An LED located next to the
respective channel's volume control illuminates when the channel is activated. Clean channel: green LED,
Crunch 1 channel: yellow LED. This feature can also be switched via the MIDI Interface Port (45), or the
footswitch jack (46); the channel selector pushbutton is deactivated once a footswitch is connected to
the footswitch jack (46).
14 CRUNCH 1 VOLUME
*MCH 1; Volume control for the Crunch 1 channel. (in front of the FX loop, affects the Send level)
15 MIDI MODE
This red LED illuminates when the ENGL MIDI Interface is connected and activated; the LED flashes when
the amp is operating in the MIDI mode.
Tip:
The ENGL MIDI Interface offers even more comfortable handling features and loads of interesting
combinations. This interface allows you to switch the defined functions via a MIDI stage board. You can
also save diverse sound combinations as presets in up to 99 MIDI memory locations, assign polychannels
1-8 via the interface and control another ENGL device equipped with an MIDI Interface Port; e.g. an ENGL
rack stereo power amp, type 930 (-> for a stereo setup!).
16 PRESENCE A
*P.A.Section; Treble control A in the power amp.
Tip:
Use two controls A and B and the respective Depth Boost pushbuttons to adjust two different
sound settings in the poweramp. This feature enhances the sound variations of the amp because you can
assign both EQs to every channel and to the Rough and Smooth modes. Another application is a
combination with two different speaker cabinets (a seperate tone control setting for cabinet A and B) or
different sound settings for Triode and Pentode operation modes.
