A Gently pull the black gain knob off the shaft to
remove it
B Plug the cord into the RGM control box
C Use a /” size drill bit to make a hole in the surface
you wish to mount the knob to
D Place the control box behind the panel and insert the
knob through the hole
E Replace the nut located in the parts bag on the shaft
by turning it clockwise and then gently push the
knob back onto the shaft
F The RGM knob is now controlling the gain of
your amplifier

A Plug supplied cord into RGM control box
B Secure control box to surface where you wish to
mount it with supplied screws
C The RGM knob is now controlling the gain of
your amplifier
The RGM is designed to be adjusted with the use of a
control knob
A Plug the supplied cord into the RGM’s socket on
the module board
B Turnoff amplifier Remove amplifier cover and
locate the Accessory Port
C Remove the two header jumpers and locate the
missing pin (“key”) on the port
D Align the blocked receptacle on the right angle
header connector with the missing pin and press
the RGM onto the mounting port
E Rotate the amplifier’s gain control clockwise
(fully) to dB
F Run the RGM’s cord out of the amp near the
RCA inputs
G Replace the amplifier’s cover and put the screws
back in to secure it to the baseplate
H Run the supplied foot cord to the location in

A Remove the RGM from the packaging and
inspect the circuit board
B Locate the header connectors soldered onto the
top and bottom of the circuit board
See illustration
C Notice that one of the openings on both header
connectors is blocked by white filler material
The RGM’s mounting system utilizes this
blocked receptacle as the “key” to insure proper
positioning when installing the RGM onto the
amplifier’s mounting port
