1-1 Description:

Dixon System's RM-35 is a self contained, rack mountable, stereo amplifier and

speaker monitor system designed to compliment the NM-250 Newsroom Mixer. The unit

employs a high quality stereo audio amplifier driving two three by five inch shielded

speakers, each in it's own acoustically treated 'enclosure'. The result is exceptional

audio quality, very low distortion and outstanding stereo separation. The shielded

speakers, along with the toroidal power transformer in it's power supply, eliminate the

concern about placing the unit in close proximity to video and computer CRT monitors.

There is only one control on the front panel. This allows the operator to switch

between 'Stereo' and 'Mono' mode to check phase and mono compatibility. This is

done with true L+R summing and with no change in volume. LEDs indicate Power and

Stereo or Mono mode.

**(The RM-35 is also available with the gain control mounted on the front panel when

it's not used with the NM-250.)

The RM-35 can be used in newsrooms and editing suites or with modulation

monitors and logging systems. It's a valuable accessory in a wide variety of facilities

and installations.

The RM-35 uses 2 premium quality shielded speakers, each in it's own 'enclosure'

inside the unit. The stereo amplifier and power supply are in the center of the unit. To

keep things clean and quiet, 1% low noise metal film resistors are used in the signal

path of the amplifiers. The result is clean, very low distortion audio and a better stereo

image. Audio inputs are on the rear panel and are the 'combo' type which accept either

XLR or quarter inch TRS connectors. The gain control is also located on the rear panel.

(See 'Set Up")

The input stage of the RM-35 is a 5532 configured as a differential amplifier. This

permits either a balanced or an unbalanced source. The unit is designed for a nominal

+4 dB input level. The input stage then feeds a resistive network and an analog switch,

a 4053, followed by a summing amplifier, again a 5532. Gain is set in the following

stage, another 5532 and the output stage is a typical NPN/PNP driver/output pair. The

amplifier drives a pair of 3" by 5" speakers, each in it's own compartment or 'enclosure'

which has been acoustically damped. This results in better audio and less vibration of

the enclosure itself.
