A simultaneous stereo recording can be made of the performance by feeding additional
console outputs to a 2-track such as a cassette or DAT recorder. The GL4000 offers
several methods depending on the application. In each case a separate output level
trim is provided so that you can match the console to the operating level of the recorder,
usually +4dBu (high level) or -10dBV (low level). AFL is provided so that the recording
level can be checked independent of the live mix :
1. Use the LR2 outputs. This gives you separate control of the left and right
signals to adjust for any imbalance in the mix. Select POST if you want the
recording to follow the faders. Select PRE to record independent of the faders.
2. Use the MATRIX outputs if you want the recording mix to be different to the
LR mix. This is often the case in live sound where the LR speakers supplement
the natural sound generated by acoustic instruments or the 'back line' sound
from the musicians own amplifiers. Typically, the LR mix may have plenty of
vocals, effects and drum kit but be noticeably lacking in guitar and other
instrument groups. Boost the content of these by raising the related group to
matrix sends.
3. Use spare AUX sends when you are already using the LR2 and MATRIX
outputs, such as in a multi-speaker system. The recording mix can be
completely different to the live mix (PRE), or set up to follow the faders (POST).

Plug the 2-track recorder outputs into the console 2-TRACK RETURN sockets. You
can check the recording using headphones or the local monitor system by pressing 2-
track STEREO PFL. The L,R and M meters show the stereo and mono levels of the
recording. Press MONO to listen to the mono compatability of the recording.

EPLAY
You can replay your stereo recording through the LR speaker system by pressing
REPLAY TO LR. The signal is sent to the outputs pre-insert and pre-fader. The 2-track
return may also be used to replay background music to the PA during intermission.
Set up a mute group to turn off the channels, groups and aux sends during replay. This
lets you leave the faders set ready for the next act.

It is increasingly common for the performers to commission multitrack recordings of the
show for their own purposes. The GL4000 provides the facility for simultaneous
multitrack recording whether operating as a front-of-house or on-stage monitor
console. Later, and without the distraction of the live sound, the multitrack can be mixed
down to stereo and effects added to produce a more balanced mix.
Record from the subgroups. Select
#
TRIM ON to enable the separate group
output level control to adjust for the operating level of the multitrack. Select PRE
if you want to record independent of the group fader which is being used to adjust
the subgroup level to LR.
Record from individual channels. Select
#
DIR OUT for output level trim of
the channel signal to the multitrack. This also lets you select PRE or POST
channel fader depending on your preference.
With these facilities, the GL4000 is a fully capable multitrack recording console in its
own right, offering the live sound engineer the ability to create his own studio quality
recordings.
