OPERATING INSTRUCTIONS

The DMS 22 has been design to operate in a similar

fashion to most mixer input strips. Anyone familiar with

mixers should have little difficulty mastering the DMS 22.

INPUT SECTION

When setting up the Input section, one should always take

as much gain as possible right at the Input. Therefore, the

highest level audio from the MIC INPUT should just about

light the OL LED. It is a good idea to experiment with

different settings to make sure the input stage is set up

properly. Failure to do so will sacrifice noise performance

down the line. Pristine 48 volt Phantom Power is available at

a push of a button with no degradation of the audio signal

quality. This is sufficient to cover most microphones on the

market and is specifically designed for fussy high end

microphones requiring full 48 volts of Phantom Power.

Verification is recommended that your mic can handle 48

volts of Phantom Power, if used. If your application requires

an inversion of the signal polarity the DMS 22 accommodates

that with a POLARITY INVERT switch. LOW

FREQUENCY FILTERS (located on the rear) are also

provided with three different settings to remove potential low

frequency bumps and such.

EQUALIZER

The EQ section of the DMS 22 is particularly interesting.

The high frequency and low frequency shelving controls

feature Rane’s patented Accelerated Slope (TM) circuitry.

This helps eliminate the unwanted influence over out-of band

signals so prevalent in standard shelving controls. What this

means is that the rolloff rates are much steeper than those

usually encountered. Additionally both high frequency and

low frequency shelving controls feature a Turnover switch

allowing the user to select the Frequency range most

appropriate to their application.

The midrange section of the DMS 22s equalizer is

parametric. The bandwidth may be set to one of three

settings: 1/3-octave, 1-octave, or 2-octaves. The center

frequency may be adjusted over a range of 95 Hz to 4 kHz.

All three bands cover an amplitude range of -15 dB to +12

dB. All of the Level controls feature a grounded center detent

thus ensuring that a “zero” setting gives you just what you

wanted: a guaranteed zero (flat) response.

The EQ IN/OUT switch provides a “hard-wire” bypass

around the equalizer section. Even though the center detents

of the EQ Level controls provide a guaranteed zero, some

engineers use the bypass to compare the EQ settings.

INDIVIDUAL CHANNEL OUTPUTS

If mixing of the two Channels is not required or desired

and you simply want to have two separate mic-to-line level

preamps, use the individual CHANNEL OUTPUTS. They are

fully balanced ¼" TRS connectors. The PAN and STEREO

OUTPUT LEVEL controls have no affect on these individual

CHANNEL OUTPUTS.

STEREO OUTPUTS

These STEREO OUTPUTS allow you to mix/split one or

two Inputs to two Output Channels. The PAN control directs

the amount of signal available to the STEREO LEVEL

CONTROL, which in turn determines the overall amount of

signal available at the STEREO OUTPUTS. They are fully

balanced XLR connectors.
