Overall GainOverall Gain
TThe overall gain of the Model 112 Stereo Power Amplifier can be
adjusted between 26 dB and 32 dB. The setting from the factory is
26 dB, which is adequate for the majority of applications, though in
a small number of situations involving low efficiency systems the
higher gain setting may be necessary. There is no sonic difference
between the two settings.
Because of the potentially dangerous voltages inside of the chassis,
it is recommended that you contact your dealer for information
regarding the overall gain setting adjustments. Note:Note: Do not
attempt to disassemble the chassis of the amplifier and adjust the
gain without explicit instructions from your dealer or Jeff Rowland
Design Group.
DC Protection SystemDC Protection System
The Model 112 Stereo Power Amplifier can produce high power
levels that, without well-designed protection circuitry, could damage
your loudspeakers and is equipped with a circuit that protects the
amplifier from DC current emitted by source components. This
system also prevents amplification of DC currents that can damage
your loudspeakers.
Do not alter the settings of the DC protection circuit, as this will
disable the ability of the amplifier to protect your loudspeakers!
These settings are for production and testing purposes only.
Because of the potentially dangerous voltages inside the chassis, do
not attempt to disassemble the amplifier.
