Koch THE GREG Bedienungsanleitung Seite 4

NOTE: Select MODE only when VIB-TREM switch [8] is
'Off'.
[5] SPEED: Adjusts the rate of the Vibrato/Tremolo effect.
[6] DEPTH: Adjusts the intensity of the Vibrato/Tremolo
effect.
[7] LEVEL: Adjusts the volume level if the Vibrato/Tremolo
circuit is switched on [8].
[8] VIB-TREM ON/OFF: This switch places the
Vibrato/Tremolo circuit in the signal path if no external
footpedal (e.g. the FS5-G) is connected to the
FOOTPEDAL jack [BP 4].
NOTE: While switching a soft popping noise may occur.
This is caused by the switching relay in the analogue tube
circuit and is perfectly normal.
[9] SEQUENCE: Determines the sequence of the
Vibrato/Tremolo and the Reverb circuits. In the lower
position the Reverb comes after the Vibrato/Tremolo effect.
In the upper position the Vibrato/Tremolo effect comes the
Reverb.
[10] REVERB ON/OFF: Switches the 'wet' reverb signal on
or off, if no external footpedal (e.g. the FS5-G) is
connected to the FOOTPEDAL jack [BP 4].
[11] DWELL: Adjusts the amount of signal sent to the
reverb tank. At low Dwell settings (2-4) the reverb sounds
much like a guitar played into a large hall. At high
Dwell settings (>4) the reverb signal will start to
sound more "springy" or 'twangy"
[12] TONE: This control affects only the "wet' portion of the
signal and acts much like a Treble control on the front
panel.
Turning the Tone control up allows more high
frequencies through from the reverb to the mixed signal.
[13] VOLUME: The reverb "wet" signal and the 'dry" signal
are mixed together at this control. Higher settings equal
more reverb.
[14] PRESENCE: Adjusts the amount of boost in the upper
mid frequency range of both channels.
[15] MASTER: Adjusts the overall loudness of the
amplifier.
[16] POWER SELECTOR: Selects half (TRIODE) or full
(PENTHODE) output power. In the TRIODE position the
amp has a more vintage tone.
BACK PANEL FUNCTIONS
[1] POWER: Turns AC power On (pilot lamp, [FP 10]) and
Off. When the switch is Off the amplifier is completely shut
down.
NOTE: When switching the amplifier on, leave the Standby
switch [FP 11] in "Standby" position for 5-10 seconds thus
allowing the tubes to heat up before switching to the
"Active" mode.
When switching the amplifier off, first select "Standby"
mode and allow the amp to dim completely before
switching the power off.
[2] A.C. POWER:
INPUT - Power cord input. The amp is equipped with a
worldwide power supply. Inside the amp a mains selector
switch can be set on one of three voltages, 100, 115 or
230. Either of these voltages will work worldwide with minor
power differences. The amp will work on either 50 or 60
hertz. After resetting the internal mains selector switch
make sure fuses are replaced with printed ratings on
rear of amp.
FUSE - Both fuse and spare fuse are located on the sled of
the fuse holder. Fuse sled can be removed with a
screwdriver. If the fuse should fail, it must be replaced
with the same type and value in order to avoid damage
to the amp and to prevent voiding the warranty.
If the amp repeatedly blows fuses, check for a bad power
tube. If tube-failure is not the cause, the amp should be
taken to a qualified service centre for repair.
WARNING: Only a qualified technician should attempt
an input voltage change. Personal injury or equipment
damage may occur if done incorrectly.
WARNING: The fuse should be replaced or the voltage
should be reset only when the power cord has been
disconnected from its power source.
[3] HT FUSE: This fuse protects the power supply in case
of tube failure. If it blows, check for a bad power tube. If
tube-failure is not the cause, the amp should be taken to a
qualified service centre for repair.
This fuse also must be replaced with the same type
and value in order to avoid damage to the amp and to
prevent voiding the warranty.
[4] FS5-G FOOTPEDAL CONNECTOR: Provides an input
for the FS5-G footpedal and disconnects the CHANNELS
switch [FP 2], the GAIN BOOST switch [FP 6], the OTS
on/off switch [TP 1],the VIB/TREM on/off switch [TP 8] and
the REVERB on/off switch [TP 10], when the footpedal is
plugged in.
FS5-G FOOTSWITCH
The included FS-5G Footpedal is equipped with four
switches:
- CHANNELS switch, for selecting channels [Overdrive
channel = red LED on].
- GAIN BOOST switch, for activating the Gain Boost in the
Overdrive channel (red LED on).
- OTS switch, for placing the OTS circuit in the signal path
- VIBRATO/TREMOLO switch, for activating the
Vibrato/Tremolo effect.
- REVERB switch, for activating the reverb effect.
[5] FX LOOP SEND: This jack provides a buffered mono
output from the preamp of THE GREG and can be used to
connect an external effects unit. This jack must be
connected with the input of the effects unit (see also
CONNECTION DIAGRAM).
[6] FX LOOP RETURN SERIAL: This jack provides an
input for an external effects unit and must be connected to
the output of the unit. When used, it disconnects the
preamp of THE GREG from the power amp.
[7] FX LOOP RETURN PARALLEL: This jack provides an
input for an external effects unit and must be connected to
the output of the unit. When used, it sends its signal to the
LEVEL trimmer [8].
[8] LEVEL: The effect's 'wet' signal [7] and the 'dry' signal
are mixed together at this control. Higher settings equal
more effect.
If this parallel loop is used, direct signal must be taken
off the effects unit's signal. For example by turning the
effects unit's 'dry/wet' control to 'wet'.
