Sonic Frontiers Power 1 - Adjustment for Speaker Load Impedance

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 8Ω (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.
