Adjustment for Speaker Load Impedance
Note: Adjustment for load impedance should only be done by an
authorized Sonic Frontiers dealer, distributor or service technician. Any
damage to the amplifier as a result of a person(s) not authorized by
Sonic Frontiers will not be covered under warranty.
Warning: Dangerous voltages exist within this amplifier.
The nominal speaker load of the amplifier was factory set to the 8
Ω
(ohm) impedance. In
the event that you should require different impedance operation, the amplifier can be set
to handle 4 or 8 ohm loads. Some experimenting of this setting may be required for
speakers which vary considerably in impedance across a frequency range. To change
the output setting have your Sonic Frontiers’ dealer follow these steps:
1. Unplug all connections to the power amplifier, namely the AC power supply cord and
wait a minimum of 20 minutes for all power supplies to discharge.
2. To remove the Transformer Cover - Remove all indicated screws. Slide the cover to the
rear and lift straight up.
.
After removing the
Transformer cover, locate
the output Transformer
for the left channel
in the left rear corner.
The output Transformer
for the right channel
in the right rear corner.
