Do not connect
the cabinets with different
impedance at the same time.
6. Phones 1/4” TRS jack socket
The output 6,3” jack socket, with
speaker simulation for connecting
headphones, allowing to play silent,
without speaker being connected.
The signal at Phones is taken from the
speaker output, after power tubes and
the output transformer. Therefore it
consist all good, that tube power
amplifier have. The signal is then
modified in the guitar speaker
emulator, to reach the similar tone to a
guitar cabinet.
Phones output is always active. This
allows to play at home silent, using just
headphones, but it's necessary to turn
the Speaker switch to “OFF”, to apply
the internal dummy load, even if no
speaker is connected. It is also
possible to use headphones in
monitoring mode - when the speaker is
connected – then the Speaker switch
must be turned to “ON” and a speaker
must be connected. It's possible to use
headphones at the same time as XLR
balanced output.
IMPORTANT: Headphones volume is
controlled by Master Volume knob at
the front panel, therefore before using
headphones, turn the Master pot down
and then adjust it to required volume.
ATTENTION!
To play silent –
without speaker active, using
just headphones – always turn
the Speaker switch to “OFF”.
Note: the simulation tone character
might sound different on various
headphones due to its different
frequency response.
HINT: To get the best tone, use high
impedance pro-line headphones.
7. Balanced line output XLR socket
Balanced line output with built-in
Di-Box, with separating transformer.
This reduces buzz and hum from
ground loops, while connecting the
amplifier to mixing consoles, home
recording systems, or other devices.
Although the line output is separated
from the Phones output, it also takes
signal from power tubes, after the
output transformer and then the signal
is modified in the same guitar speaker
emulation, as the Phones output.
Volume is controlled by Master Volume
knob at the front panel.
The output is always active, no matter
if the Speaker switch is at “ON” or
“OFF”. It works with headphones
connected or without.
8. Speaker switch
Switch connects or disconnects all
speaker output sockets.
Position “ON”: If the switch is at
“On”, then the signal goes to speaker
output sockets and the internal speaker
works (if connected), or any other
cabinet connected instead. Note: Use
only one output at the same time.
Position “OFF”: When the switch is at
“OFF”, the signal goes to the built-in
dummy load, so the tubes work
properly – as they were connected to
the speaker. Then, no sound comes
from any speaker connected. In this
position, it's allowed to disconnect
speakers.
WARNING: When using amplifier
without speakers connected – when the
Speaker switch is at “OFF”, the metal
chassis might become very hot. It's
therefore recommended to operate at
low volumes to keep temperature low.
