Figure 10. Wire gauge versus
maximum wire run (with a
maximum loop resistance of
0.07 ohms) for less than 0.2 dB
response error.
NOTE: “Loop resistance” is the
DC resistance measured at one
end of a loudspeaker cable, with
the other ends shorted together.
CONNECTIONS
REVEL ULTIMA GEM loudspeakers can be connected to an audio
system in three different ways: single-wired, bi-wired or bi-amplified.
Please read the following sections before proceeding with actual con-
nections. Also, be sure to observe the following points:
• Use high-quality speaker cable with a maximum total loop resis-
tance (for each wire run) of 0.07 ohms or less. Use the chart in
Figure 10 below to determine the maximum wire gauge.
A high loop resistance will result in mis-termination of the
filter networks, and serious degradation of sound quality.
Use high-quality connectors on the loudspeaker cables. Consult
your Revel dealer as to specific solutions for your application.
• Turn off all audio system power before making any connections.
• Read the owner’s manuals that were included with your audio
components to confirm their connection procedures.
• Verify correct polarities (i.e., + to + and − to −) when making
connections. Failure to do so will cause poor imaging and
diminished bass response.
• For bi-wired or bi-amplified applications, remove the shorting
straps (see Figures 12, 13, and 14 on the next three pages).
SINGLE-WIRED SYSTEM CONNECTIONS
For most applications, simply leave the shorting straps in place and
connect the + and − from a single amplifier channel to the HIGH
FREQUENCY INPUT terminals, as shown in Figure 11 (on the
next page).
