Description Stereo Mixing Console
                                    The SD 12/2 stereo mixing console has been designed to give
maximum flexibility in both sound reinforcement and
recording situations.

The unit mill satisfy all normal requirements in terms of
operational facilities and provision has been made for the
addition of external control equipment.

Each channel features a circuit breaking line input enabling
the operator to insert compressor/limiters or any other
studio device without the additional expense of an external
patch bay. Each input channel incorporates a direct post
fade line output which enables the operator to feed an
equalized signal to any external system. This feature is
discussed in greater depth in the operational text.

The SD 12/2 has a comprehensive monitor system uihich allows
quality and calibration checks to be made on all functions
of the unit, without disturbing any of the programme outputs
at the time.

Provision is also made for monitoring of external programme
sources such as tape machines, broadcast programme cues,
stage to desk communications etc. Equalisation is
comprehensive with two level controls in the critical mid
range spectrum. Separate foldback equalization is provided
which is essential for positive control of acoustic feedback.

A full range of accessories are available for the SD 12/2
including a custom built heavy duty flight case and a
customer tailored multiway cable assembly.

The SD 12/2 has been constructed with simple 'in field'
servicing in mind. Removal of the base panel exposes the
entire circuitry and any channel module can be removed
without interfering with the rest of the unit - invaluable
in emergency situations.
