General
6.01 Interfacing a tape deck for recording purposes.
The M2 master module is fitted with a total of two stereo pairs of record output sockets, all using
RCA type phono sockets. One pair carry the main output signal: this output is controlled by the
master faders and the system must be operated normally with master faders open sufficiently to
give a satisfactory recording level. The other pair of record outputs carry music only, pre-master
fader signals. These outputs are not controlled by the master faders and may be used where no
mic signals are required to be recorded.
The M2 modules have additional XLR outputs carrying music only, pre-master fader signals.
These outputs are not controlled by the master faders and may be used where no mic signals
are required.
If Output 2 is not being used for an additional output zone then it’s balanced, pre-master fade
signal offers flexibility as the music and mic signal levels are independently adjustable by means
of the rotary front panel controls.
If a CZ1 zone module is fitted to the CXM mixer, it is possible to use the auxiliary outputs on
Zone 2 or Zone 3 for recording purposes. Possibly the best option would be to use Zone 2 in the
pre-fade mode. The mic and music faders would then control the recording level independently of
the master faders.
Finally, if you are really stuck, the aux send facility could be used (in the post-fade mode) but to
keep noise levels to a minimum, only open the channels you intend to use.
6.02 Unbalanced Mode
If it is required to have stereo unbalanced outputs from either the Main or Zone groups, as
opposed to the normal balanced mode, pin 2 should be used for an in phase signal and pin 1 as
ground, note this will give a 6dB reduction in output level. Pin 3 may be used as an output if an
anti-phase signal is required instead. Do not connect either output pin to ground. If any input XLR
connector is also unbalanced, the same phase should be used as hot.
6.03 Earthing
The 0V rail on the CXM mixer is connected to the mains earth via the power supply lead and the
mixer power supply must always be earthed. A green earth terminal is provided on the master
rear panel to earth turntables, etc. If any mains powered input apparatus has it’s own earth
connection to a different point mains point, then earth loop hums might be caused. This 'hum'
can be remedied in several ways. One method is to operate all possible circuitry in the balanced
mode and connect the signal cable screen at the receiving end only. Alternatively, try to re-route
the mains supply of the apparatus to the same point that the CXM power supply is connected to.
