5.1.1 Summing amplifiers [Master]
The summing amplifiers are mixing the modulation coming from input channels 1 to 6. The output level of the
Groups is controlled per pairs: 1-2 and 3-4. The two rotary stereo master faders are retractable and adjust the
output level from -infinity (mute) to 0dB (unity gain).
The nominal output level is set either at +6dBu or +4dBu (please specify when ordering). It corresponds to a
reading of "0 dB" on the modulometer. The peak meters are factory programmed and their ballistic can not be
changed by the user.
The sums of the 4 groups are then sent to the main outputs OUT 1 to OUT4. These four master outputs are
electronically balanced, transformer less.
The output connector for OUT 1 to OUT4 is an XLR-3 male where:
Pin1 = Gnd / Pin2 = High (+) / Pin3 = Low (-).
To connect the main output on an unbalanced receiver's input, pin 1 & 3 must be bridged and connected to
the Gnd of the receiver's input. The pin 2 is to be used as an unbalanced line output.
Master outputs 1 & 2 are also available on the Sub-D25 connector [Line Outs] and on the digital out AES # 4 if
the mixer is equipped with the optional A/D converter and, if fitted, on the optional connector [OPTION] on the
rear panel.
WARNING:
Meanwhile the outputs of the SX-ES64 are protected against DC voltages, we strongly
recommend not to connect a phantom power to the output of the mixer (for example when
connecting to a camera input, make sure that the phantom power of the camera is turned off).
5.1.2 Switches [ SLATE – Off – RET ]
The SX-ES64 has two extra buses, in addition to the main mix buses; a [SLATE] bus and a stereo bus coming
from the returns 1 to 4 [RET].
The three positions switches underneath the master faders assign and mix either the "Slate Bus" or the
"Return bus" to the pair of groups 1-2 and 3-4.
Left
← SLATE position: assign the Slate bus to the group's mix bus as soon as the [SLATE] push
button is depressed
Middle OFF position: No assignment to the mix bus.
Right
→ RET position: assign the stereo Return bus to the mix bus.
5.1.3 Group Monitoring [ MON ]
The [MON] push buttons underneath the master faders sends the modulation of the groups 1-2 and 3-4 to the
main monitoring.
The two keys can be used individually to listen separately to the groups 1-2 or 3-4 or simultaneously to
summon the 4 groups on the main monitor.
While in stereo mode, the odd groups 1 and 3 are heard on the left channel and groups 2 and 4 on the right
channel of the main monitoring. A selector in the main Monitoring section determines the listening mode (see
Main Monitoring Chapter).
