USING PHANTOM POWER  
Phantom power is a means of powering condenser microphones through the micro-  
phone cable. The RM65b has individually switchable 36 volts of phantom power for  
each of its 6 channels through the XLR jacks. The DIP switches on the rear of the unit  
are for switching the power on and off. When the little switch tab is down, the power is  
on. The number on the switch corresponds to the channel that is receiving the power.  
If phantom power is not needed, it should be switched off to avoid possible damage  
5
to a microphone, or degraded sound quality.

OPERATION  
The RM65b is ideal for small combo groups where a small number of instruments and  
microphones need to be mixed together. Refer to Figure 2 for an example of how to  
connect the inputs and outputs of your RM65b. Connect microphones to balanced XLR  
cables and to the XLR inputs. If any of these microphones are condenser microphones,  
they will require phantom power. To turn on the phantom power for an individual channel,  
set the phantom power switch for that channel to the ON (down) position. Instruments  
may be played into a microphone which is connected as indicated above, or if you have  
active pickups in your instrument, simply connect the output of your instrument to an  
RM65b Line Input as the acoustic guitar is shown.  
The RM65b may also be used for recording. Connect microphones, instruments, and  
effects to the inputs as described above - the connect the Right and Left outputs to your  
recording device and set the levels accordingly.  
CONFIGURING THE 1/4” INPUTS AS INSERTS  
NOTE:You are responsible for any damage that may occur during this process.  
Carefully remove the seven screws that hold the lid of the RM65b to the chassis. Refer to  
Figure 1 for the placement of the input to insert jumpers. To convert the 1/4” Input jack to  
become an “Insert”, move the appropriate channel jumpers from INPUT to INSERT. Note  
that channel 5 jumpers are moved perpendicular to their original placement for the Insert  
position rather than parallel.  
Electric guitars and basses normally are connected to an instrument preamplifier.  
Amplifiers may have microphones placed in front of the speaker, or if the amp has a line  
level output (check with the amplifier’s owners manual) - it may also be connected to the  
mixer directly. Keyboards and sound modules are connected directly to the RM65b line  
inputs as shown.  
Figure 2  
FX LOOP  
To use the FX Loop, connect a 1/4” unbalanced cable to the FX Send and to the Input on  
your signal processor or effects device. Connect the Outputs of the signal processor or  
effects device to the RM65b FX Return jack. You will need an “Insert” type of cable (shown  
to the rigth) to adapt the dual 1/4’ end connected  
to your signal processor, to the 1/4’ TRS end of  
the RM65b. The level of the effect will be con-  
trolled by the settings on the channels’ FX Sends and by the Output  
Level of your effects device, The overall level of the effect to the final mix  
will be controlled by the FX Return level on the front of the RM65b.

To use the Monitor feature of the RM65b, connect the Monitor Out jack to a monitor  
amplifier via a 1/4” unbalanced cable. Each channel’s monitor level is controlled by that  
channel’s Monitor level setting. Be aware that the RM65b has no master monitor level, so  
you will need to set the overall monitor level with the monitor amplifier and the Monitor  
Levels of each channel.
