MAKING CONNECTIONS
The Gem2 features gold-plated binding posts and jumper straps
that allow it to be configured for single-wired, bi-wired, or
bi-amplified connections.
Before making connections, note the following:
• The standard connection method uses a single loudspeaker
cable. The Gem2 is equipped with two pairs of input
terminals to allow for bi-wiring or bi-amplification. While
Revel does not endorse one particular connection method
over another, these additional connection options are
available if desired. The design of this loudspeaker is such
that optimal performance can be attained using the standard
connection method.
• Make all connections observing the proper polarity,
positive-to-positive (+) and negative-to-negative (-).
Connections that do not observe the proper polarity will
cause poor stereo imaging and diminished bass response.
• Use high-quality loudspeaker cable with a maximum total
loop resistance of 0.07 Ohms or less (for each wire run). Refer
to the following table to determine the appropriate wire
gauge.
Minimum Wire Gauge
Caution
Never make or break connections unless all system
components are powered off.
Remove the input panel jumper-straps identified in Figure 4,
page 11, before making bi-wired or bi-amplified connections.
Failure to do so may cause damage to some power amplifiers.

Note
High loop resistances that exceed 0.07 Ohms (for each wire run) will
cause the filter network to be mis-terminated, resulting in
considerable degradation of sound quality.
