Setup and Guided Tour

Operation of the MS Series is basic and straightforward. The controls and operation are mostly intuitive and self-explanatory, but are discussed here in detail to allow any user to operate it successfully.

Install the unit in its rack and connect the external power supply to the 5-pin DIN DC POWER INPUT connector on the rear panel. Connect an appropriate line cord to the power input on the supply box, and to the AC mains. The power supply accepts any input voltage from 100 to 240 VAC.

Analog Audio Monitoring

Connect active analog audio sources to each of the balanced XLR inputs on the rear panel. (Please refer to Figures 1-4 on page 9 for the locations of controls and indicators.) When the unit is powered up and audio above -28 dBu is present, the SIG (Signal) LEDs next to each input and output connector should flash. If you have a unit with digital capability, set the A/D SELECT button to

ANALOG.

Next, vary the VOLUME and BALANCE sliders (BALANCE is present in non-video units only) to confirm that they affect the speakers and headphones identically. The BALANCE slider should move the stereo image from full left to full right. The headphones DO NOT disable the speakers when they are inserted into the HEADPHONE jack. Headphone monitoring is intended to minimize the distracting effects of surrounding ambient sound for the operator. The speakers are still active when the headphones are plugged in to provide audio to others in the immediate area for confidence, while the operator is monitoring the audio specifically. Nevertheless, the speakers can be muted if desired by pressing the SPEAKER MUTE button. An indicator LED lights when the speakers are muted. The SPEAKER MUTE button does not affect the headphones.

With audio input, the Level Meters will vary according to the BALLISTICS selected, either VU or PPM. Note that there is a PK (Peak) LED that will illuminate when the audio level exceeds +4 dBu. The movement of the meters is from -40 dBu to +3 dBu, left to right as is seen in analog metering. The zero reference of the meters may be set to either +4 dBu or +8 dBu with the REF/dBu button. Successive presses of the button will toggle between the two references. An indicator LED glows above the selected reference, which affects all meters on the unit.

NOTE:Choose VU for a slower, time-averaged meter response. Choose PPM for an extremely fast response which displays all peaks.

The brightness of the Level Meters’ LED displays can be varied by the DIMMER control at the very left side of the front panel assembly. This control will vary the brightness from “Full On” to slightly visible. The Level Meters cannot be dimmed completely as this may cause an erroneous reading by operators not aware of the dimmed setting. This adjustment requires a small flat-blade screwdriver and has a travel of 270 degrees of rotation.

When normal, in-phase stereo signals are applied to the MS Series unit, the PHASE indicator will glow green, with an occasional yellow flicker. If one channel is disconnected or reduced to zero, the color will change to steady red. It will also be mainly red for out-of-phase stereo.

NOTE: Out-of phase stereo is not compatible with conversion to mono. The out-of-phase condition should be corrected, or there may be substantial level loss when left and right are summed to mono.
