The STEREO Input Channel
Dual stereo inputs
Each of the two stereo channels has two
stereo inputs which can be used separately, mixed together or split so
that one feeds the channel, the other routes direct to LR. For example,
you could mix two sound effects playback devices or two reverb re-
turns together into one channel. This can be useful in saving channels,
letting you mix many inputs in a small space. The L input signal normals
through the R input socket so that a mono source may be plugged in to
feed both left and right sides of the stereo channel.
ST1, ST3
Unbalanced TRS inputs. The GAIN control adjusts from
fully off to +16dB gain. Press the ST1(3) switch to turn the input on.
Routing mode switch
Recessed switch to prevent accidental
operation. In the normal up position the ST1 (ST3) signal mixes with
ST2 (ST4) into the stereo channel. When pressed the signal is routed
direct to the LR mix instead of the channel. This lets you use these
inputs as simple stereo returns in addition to the full stereo channels,
providing four independent stereo sources to the LR mix.
ST2, ST4
Balanced TRS inputs. The GAIN control adjusts from
fully off to +16dB gain. Press the ST2 (4) switch to turn the input on.
These inputs always feed the stereo channels.
EQ
A 4-band fixed frequency EQ provides independent control of
four frequency bands. HF and LF are shelving filters which affect high
frequencies above 12kHz, and low frequencies below 80Hz respectively.
Use EQ IN to compare the sound with the equaliser switched in or out
of circuit. HM and LM are bell shaped peak/dip filters which affect fre-
quencies centred around 2.5kHz and 250Hz respectively. These have a
width (Q) of 1.8. All bands can be boosted or cut by up to 15dB and
have a centre detented 0dB position.
AUX SENDS
These work as described for the mono channel.
The L and R sides of the stereo signal sum together to feed each aux in
mono. This can be changed using an internal jumper so that L feeds
auxes 1, 3 and R feeds auxes 2, 4. The auxes are always post-EQ.
BAL
Balances the level of the L signal against the R signal to compen-
sate for differences in the source signal, or to position the signal within
the stereo image. The centre equal level position is detented for quick
resetting.
MUTE
When pressed the channel signal is turned off. This affects
the feed to the LR mix, groups and pre and post-fade aux sends. The
red indicator lights when the channel is muted.
PFL
Press PFL to display the summed L+R pre-fade channel signal on
the main meters and listen to it in the headphones and local monitor
without affecting the main outputs. The red PK indicator half lights to
show that PFL has been selected on that channel.
PEAK
The red indicator illuminates when the channel pre-fade signal
is within 5dB of clipping. This gives you enough warning to reduce the
GAIN control before you hear signal distortion.
SIGNAL
The green signal presence indicator lights when the chan-
nel pre-fade signal is greater than -12dBu.
ROUTING
As the mono channel, routes the left signal to L and
odd groups, right signal to R and even groups.

- A rotary control adjusts the level of the signal to the m output xlr the source is selected using the mode switch above the control this is recessed to prevent accidental operation use a pen or pointed object to set the position in the up position flush with the panel the post fade l and r mix is summed to provide a mono source use this in foh mode to feed a mono pa fill delay or zone speakers or even a mono broadcast or recording send 19

- Console monito 19
- In monitor mode press the switch to create an engineer s monitor wedge feed from the afl pfl mix it is common to use a wedge speaker of the same type used on stage to listen to and check the various monitor mixes being sent to the performers together with the group aux rev function the w 19
- Lr master 19
- M maste 19
- Select either lr or 2 track return as the default source using the l r 2trk switch pressing pfl or afl elsewhere on the console automatically overrides the current monitor source with the signal from the channel or mix selection the red pfl afl active indicator illuminates and the console meters display the active signal 19
- Separate faders control the main mix l and r output levels they provide 10db maximum boost each master includes a 4 led bar me ter an afl switch and a mute switch so that l and r can be separately moni tored and muted this is most useful in monitor mode where these masters carry the aux5 and aux6 signals 19
- The console main meters provide 12 led indicators to accurately display the signal level of the selected monitor source reduce the signal level if the red 16 peak indicator lights for optimum performance the signals meter an average 0 with loudest peaks reaching around 6 19
- The master section 19
- These function in the same way as described for auxes 1 to 4 the rev switch reverses the aux5 mix with l and aux6 mix with r for operation in monitor mode when selected the aux signals are presented to the l and r xlr outputs complete with their inserts the lr mix swaps on to the aux trs jack outputs note that the lr mix always feeds the matrix regardless of mode selected 19
- 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 headphones around 100 ohms impedance are a popular choice 19
- 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 19

- Factory default for the mono channel pre fade auxes is pre insert pre eq this is popular with many users mixing monitors from foh it pre vents the channel eq and inserted compressors affecting the monitor mix move the jumper from a to b to change this to post insert post eq if preferred note that auxes are always post mute 25
- Factory default is aux 1 4 switched aux 5 6 switched you can change these settings for different combinations of pre post or switched auxes by cutting and re soldering the links refer to the system block diagram to explore the possibilities make sure you set all mono and stereo channels the same we rec ommend you only change these settings if absolutely necessary 25
- Factory default is pre fader this is common for live recording to multitrack the live mix fader movements do not affect the recording move the jump er from c to d to change to post fade post fade is appropri ate when using the output as a direct channel effects send 25
