DA6 OPERATORS’ MANUAL

Interference:

If the unit is to be used where it maybe exposed to high levels of
disturbance such as found close to a TV or radio transmitter, we
suggest that the unit be operated using an optional wiring of the
balanced configuration. The screens of the signal cables should be
connected to the chassis connection on the XLR connector as
opposed to connecting to pin1.
The DA6 fully conforms to the EMC standards.

Ground Loops:

If  ground loop problems are encountered, never disconnect the
mains earth, but instead, try disconnecting the signal screen on
one end of each of the cables connecting the DA6 to the patchbay.
If such measures are necessary, balanced operation is
recommended.

ISOLATION TRANSFORMERS

The DA6 has the capability of being isolated at its outputs using low impedance (600

)

balanced transformers. Each output can be individually isolated, and it is possible to
have mixed configurations where some outputs retain their default connection of
electronically balanced. Isolating transformers can be factory fitted, or alternatively,
retro fitted by a Drawmer appointed service agent, or a suitably qualified engineer.
Contact Drawmer for specifications.

Any warranty will be void if isolating transformers are fitted by non-approved
methods, or, if unspecified transformers are fitted.
