he overall gain of the Model 10 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 System

DC Protection System  

The Model 10 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.
