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.

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.

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.

MONITOR

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.

Connect the Right and Left Main Outputs to the main amplifier(s) and make sure the amplifier is the correct rating for the speakers. If you are operating in mono, use either the Right or Left Output.

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.
