Balanced Audio REX II Power - Manual (Page 6)

Physical Placement
It is recommended that you provide open space above the unit for proper
ventilation, with no electronic components or shelves placed directly
overhead.
Mount the unit on a hard surface with proper ventilation underneath.
Avoid placing the unit directly on a carpeted floor, as doing so will block
the ventilation slots in the unit’s bottom cover.
Connecting the REX II Power to Your System
For Balanced Preamplifiers:
Use balanced XLR interconnects. The left and right channel input
connectors are clearly marked on the back panel of the REX II Power.
Note: The REX II Power XLR inputs are wired as follows:
Pin 1: common/shield
Pin 2: positive
Pin 3: negative
For Single-Ended Preamplifiers:
Single-ended preamplifiers have RCA connectors. The REX II Power power
amplifier is designed to work with either balanced or single-ended
preamplifiers connected to its inputs. All that is required to connect a
single-ended preamplifier with RCA connectors to the REX II Power’s
inputs is the optional balanced to single-ended adapters. These adapters are
available from Balanced Audio Technology.
For Speaker Connections:
The speaker connectors are clearly marked on the back panel of the REX II
Power amplifier. There are three sets of output taps marked LOW,
MEDIUM and HIGH for connecting a variety of speakers to the REX II Power
output. Please note that some experimentation may be required. Try
each output tap until you find the one that gives the most balanced
performance in your system.
NOTE: Please refer to Figure 1 for proper connection and polarity.
