INSTALLATION MANUAL
Switch position depends on three things:
1. The minimum impedance rating of the amplifier being used.
2. The number of speakers being connected to the amplifier
channel.
3. The nominal impedance of the speakers being utilized. Once
the above information has been determined, use the following
equations to determine the correct Impedance Match setting for
each specific application. Two equations are necessary:
Impedance Rating
#1
of Speakers
# of Speakers Connected
to Amp Channel
Example:
Amplifier's Minimum Impedance Rating = 8 ohms
# of Speakers on this Channel = 4
Speaker Impedance = 8 ohms
#1
8 Ohm Speaker
4 Speakers
Most speakers are rated at 4, 6, or 8 ohms. If connecting speakers
of different impedances to an amplifier, an average impedance
must be determined; i.e. one pair of 4 ohm speakers is the
equivalent of 2 pair of 8 ohm speakers. All 6 ohm speakers should
be entered into the equation as 4 ohm speakers. All volume
controls connected to an amplifier channel should have the same
Impedance Match setting. Never create settings that cause the
amplifier to see an impedance below its minimum impedance
rating as this can cause damage to the amplifier.
