Connecting headphones
Connect headphones with a 6.3mm stereo jack through output 17.
AMP1
™
automatically activates a headphone amplifier when loudspeaker
ports 18 and 19 are not in use.
You regulate the headphone volume with the MASTER 3 control.
It is advisable to use some reverb. If you do, the guitar will sound a lot more
natural through the headphones, and you’ll have more fun playing.
Connecting to a mixing desk
Connect RECORDING OUT 17 with a guitar cable or stereo jack cable with
the mixing desk’s Line In. The stereo jack provides a symmetrical signal, which
delivers a better signal if you’re using a cable longer than 10 metres. If you
want to use your mixing desk’s microphone input, you’ll need to adjust the
level with an adapter (see image below).
The signal level is directly dependent on the MASTER and PowerSoak
(if activated) settings.
Recording Out
You can connect either headphones or mixing desks to this multifunctional
port. An elaborate filter circuit simulates the sound of a guitar amp cabinet.
These days, there are lots of applications that require a good direct signal
from a Recording Out. That’s why AMP1
™
works with one of the most
elaborate, fully analogue speaker simulations. A total of seven different
filters simulate the tonal character of a guitar amp. The signal sounds open
and fresh – without sounding scratchy – and delivers powerful bass, without
“booming”.
With such a large frequency spectrum, you can even fine-tune the Record-
ing Out signal for every application – because removing certain frequencies
often sounds a lot more musical than adding frequencies. This way, you always
get your perfect, consistent sound, directly into the PA or for recording.

In-ear quality
These days, in-ear monitors are often used on stage to improve a band’s
sound. For this, the Recording Out signal is sent to a mixing desk, where
it is mixed with the other instruments. This mix is then sent to an in-ear
system. By using this elaborate speaker emulation, you get an authen-
tic and constant guitar sound in an in-ear monitor system, which – in
contrast to a miked sound – never changes.

Silent Recording
AMP1
™
provides a well-balanced recording signal for silent recording without a loudspeaker. Because AMP1
™
’s power amp reacts to the loudspeaker (current
feedback), the recording sound changes if you use a loudspeaker. You can hear the difference even when using quieter Master settings. When you’re connected
to a loudspeaker, the sound has less mids and more bite.
