OPERATION AND SET UP

POWERING

We recommend using 9V alkaline type batteries, however Lithium or NiMH bat- teries work as well.

For AC power, Rolls provides the model # PS27 12 VDC supply to power the MX410.

INPUT CHANNELS

The inputs to the MX410 consist of four, microphone preamplifiers. Each channel has sufficient gain to accommodate nearly all microphone types.

The MX410 input channels can be used with balanced or unbalanced connec- tions. When unbalancing - ground pin-3 to pin-1.

The AUX INPUT jack is provided for recording stereo sources such as CD play- ers, MP3 and DVD players, etc.

OUTPUTS

The MX410 is designed with two individual balanced male XLR output jacks. Each output is isolated providing excellent signal connectivity and noise perfor- mance.

These outputs are generally connected to a recording device or other input look- ing for a line-level signal. In the event you need to connect the MX410 output to a mixer’s Microphone Input, set the Output Level select switch to MIC level. This way the MX410 output is attenuated down, and will be more compatible with an input looking for a microphone level signal.

INDIVIDUAL CHANNEL LEVEL CONTROLS

The Level is the primary channel volume control. Level can be set to a nominal level (around 12 O’clock) providing the maximum amount of variance and head- room.

L C R SWITCHES (Left - Center - Right)

The Stereo orientation switches routes an input channels signal between the Left, Right and both outputs.

METERING

The MX410 features two calibrated, LED meters. Meter ballistics correspond closely to how the human ear perceives loudness and provides a good visual indication of how loud a signal will be.

QUICK START GUIDE

For those familiar with ENG or field mixers, this guide highlights basic functionality to begin operating your MX410.

POWERING

To power the MX410 and get it ready for operation:

1.Insert - 2, 9-Volt, alkaline batteries into the battery compartments. Insert with the correct polarity.

Or, connect external DC power (the Rolls PS27) 12 VDC to the MX410 DC Input connec- tor.

2.Press in the POWER button.

INPUT CHANNEL SETUP

To set up a gain level for an input channel:

1.Connect a signal source (microphone) to a channel input connector.

2.If you’re using a condenser microphone, activate the Phantom Power by depressing the phan switch.

3.Set the LEVEL Control at the 12 O’clock position (again - just a starting point).

4.Set the channel L C R switch for the desired signal position in the stereo field.

5.Engage the side panel “low cut” switch if needed. To reduce unwanted wind noise.

6.Verify there is signal present on the output meter(s).

OUTPUT CONNECTION

To connect to the MX410 main Outputs:

1.Connect an XLR cable to the LEFT and RIGHT Outputs of the MX410.

2.Set the output level switch to either LINE (switch in), or MIC (switch out).

3.Verify that the next device in the signal chain is receiving signal from the MX410.

HEADPHONE MONITORING

1.Connect stereo headphones to the HEADPHONE output on the front panel. NOTE:

THESE MUST BE STEREO HEADPHONES OR EARPHONES - USING MONO PHONES WILL DAMAGE THE MX410.

2.Set the PHONES level to 0.

3.Verify signal in the phones by slowly bringing up the PHONES level control.

4.Set the PHONES level control to a comfortable level.
