2-TRACK REPLAY and CONSOLE MONITOR
2TRK REPLAY
A stereo source such as a recording playback or
walk-in CD can be routed directly to the main LR mix. Adjust its level
from fully off to +10dB gain using the rotary control. You can check
the source on the meters and in the headphones before bringing it
into the mix by selecting the 2TRK monitor switch.
Console Monitor Comprehensive engineer’s headphones and
local monitoring is provided. Select the source from the monitor
select switch bank. Pressing PFL or AFL elsewhere on the console
automatically overrides the current monitor source with the signal from
the channel or master selection. The red PFL/AFL active indicator
illuminates and the console meters display the active signal.
The console monitor meters provide 12 LED indicators to accurately
display the signal level of the selected monitor source. Reduce the
gain or level if the red ‘+16’ peak indicator lights. For optimum
performance the signals should be adjusted to read an average ‘0’
with loudest peaks reaching around ‘+6’.
Use the MONITOR level control to adjust the level in the headphones
and local speaker monitor. We recommend you use closed ear
headphones in the range 30 to 600 ohms designed for live sound
monitoring. 100 ohm headphones are a popular choice.
Three headphones sockets are provided for convenience. One ¼”
standard TRS is at the front under the armrest, a second at the top
near the talkback mic. A small 3.5mm socket is also provided for
plugging in headphones or earpieces fitted with a mini jack. It is useful
to monitor an in-ear mix using the same type of earpiece as used by
the performers.
WARNING: To avoid damage to your hearing do not
operate any close-to-ear monitoring such as headphones for long
periods at high volume. Continued exposure to high volume
sound can cause frequency selective or wide range hearing loss.
Stereo Monitoring The GL2800 has been designed to offer
maximum capability for working with multiple stereo mixes such as
IEM and recording feeds. It is important to be able to hear exactly
what you are sending from the console. Press AUX 9-10 to check the
stereo aux mix. Press one switch to check a matrix in mono, two to
check a related pair in stereo. For example, press MTX1 to listen to a
mono fill mix, or press MTX1 and MTX2 together to listen to a stereo
recording mix.
Monitor Selection With all select switches in the up position, no
source is monitored unless PFL or AFL is activated. Press a switch to
select the required monitor source. Press two together to select stereo
as described above. Switches nearer the faders take priority. For
example, press L-R to listen to the main mix. Then press 2TRK to
override the L-R source until it is released.
