INSTRUCTIONS

Unpacking

The packing box for the Duet 350 Amplifier should arrive in good condition. Please
inspect for damage to the carton, although this is most unlikely due to the strength of
the carton construction. Open packing carefully and save all foam pieces and boxes
for reuse in the event that the unit must be shipped in the future. Should the boxes
become lost, please contact the factory for replacement cartons.
The carton should contain:
- Duet 350 Amplifier
- 1 heavy duty A.C. cable
- 1 3/32 Allen wrench
- 1 warranty card
- 1 owner's manual
- spare fuses

Installation

Be certain the amplifier is installed so that it has proper ventilation. Placing the unit
in a small, close-fitting enclosure is not recommended. Room air temperature should
not exceed 122 degrees F./50 degrees C.
Cable and Adapter Selection
The Duet 350 Amplifier has three-pin Fischer connectors for highest quality balanced
line input capability. It is recommended that input connections be made using Cello
Strings cable. Cello Strings are stocked in lengths of 1,1.5,2,3,5,8 and 10 meters.
Terminations are available to suit the particular components of your system. Custom
lengths are available on special order. If it is necessary to convert Fischer inputs to
RCA, use the E3 adapters. The best way to convert to single ended operation is to use
Cello Strings cable (which has three conductors and a shield) with Fischer male on
one end and RCA connector on the other. This preserves the three-wire system from
the amplifier to the source unit and provides better grounding and common-mode
rejection. To interface with XLR systems, it
be used with Fischer male on one end and XLR female on the other end.
