Impedance Match Settings - Elan VSOS Instruction Manual

INSTALLATION MANUAL

Impedance Match Settings

Switch settings on the VSOS/VMOS determine the Impedance
Match settings. See diagram for position of Override Jumpers.
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 fol-
lowing equations to determine the correct Impedance Match set-
ting for each specifi c application. Two equations are necessary:
Impedance Rating of Speakers
# of Speakers Connected to Amp Channel
Minimum Impedance Rating of Amp
System Impedance
8 Ohm Speaker
4 Speakers
8 Ohm Stable Amp
2 Ohm System Impedance
