Internal Adjustments

Overall Gain
T
he overall gain of the Model 301 Mono 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 some
systems involving low efficiency loudspeakers may require the higher gain setting. 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: 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.
