Dixon Systems Model RM-35
4
1-8 Set Up:
The RM-35 can be set up in a few easy steps. Once the unit has been inspected,
slide and secure the monitor into the rack. Connect the audio signals via XLR or
quarter inch TRS connectors. Plug the unit into the AC mains. (The RM-35 operates
from 110VAC - 60Hz power.)
Adjust the volume control on the rear panel. The RM-35 is designed to be driven by
a balanced source at a nominal +4 dB level. When used with the NM-250, the volume
control on the RM-35 should be at approximately ‘one o’clock’. If used with another
audio source, be sure the monitor is not over-driven. AVOID CLIPPING! Audible
distortion (or other nasty things) will occur.
Best performance is achieved when using balanced, shielded cable; however
satisfactory results can sometimes be realized without it. The design of the input stage
permits unbalanced sources to be applied to the balanced inputs. The drawings below
show both balanced and unbalanced connections. (Only one channel is shown.)
Balanced
Unbalanced
Note: When using balanced line, only one end of the line should be grounded. This
will help avoid ground loops. As shown above, the ground would be connected at the
‘send’ end and not connected to the RM-35.
