INTRODUCTION
OPERATION AND SET UP CONT.
Thank your for your purchase of the Rolls MX410 Field Mixer; Professional ENG
mixer. Please read and review this manual carefully as it contains important
information regarding the proper use and care of the MX410.
INSPECTION
1. Unpack and inspect the MX410 box and package.
If obvious physical damage is noticed, contact the carrier immediately to make a
damage claim. We suggest saving the shipping carton and packing materials for
safely transporting the unit in the future.
2. Please visit our web site at www.rolls.com and click on the Register Your
Warranty Here button.

Connectors: 4 ea. Female XLR, 2 ea. Male XLR,
3 ea. 1/8” (3.5mm), 1 Center Negative power jack.
LOW-CUT FILTERS
Each channel of the MX410 features a switchable Low-Cut lter set at 100Hz.
These Low-Cut lters (sometimes called “High Pass”) cut frequencies below
100Hz signal and are e ective for reducing wind noise. For several audio applications engaging the Low-Cut lter is bene cial, since little usable audio information exists below 100 Hz. Especially for speech recording.
PHANTOM POWER
The MX410 can provide up to 10 mA of current to each input, su cient for the
most power-hungry condenser microphones. The MX410 Phantom Power utilizes
a xed DC voltage which is resistively applied to pin-2 and pin-3 of an XLR input
connector relative to pin-1 (there is no voltage di erence between the signal on
pins 2 and 3; a dynamic microphone may or may not operate normally in the
presence of phantom power).
It is generally a good practice to turn o phantom powering when not using a
condenser microphone, as it can capacitively couple noise into the mic inputs
with poor mic cables. Also, be sure to turn o phantom powering when using ribbon microphones since an improperly wired cable can permanently damage the
microphone.

OPERATION AND SET UP
FEATURES
POWERING
We recommend using 9V alkaline type batteries, however Lithium or NiMH batteries 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 preampli ers. Each channel
has su cient gain to accommodate nearly all microphone types.
The MX410 input channels can be used with balanced or unbalanced connections. When unbalancing - ground pin-3 to pin-1.
The AUX INPUT jack is provided for recording stereo sources such as CD players, 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 performance.
These outputs are generally connected to a recording device or other input looking 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 headroom.
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.
- Four balanced XLR Inputs
- Two transformer-balanced XLR Outputs
- Switchable Output Level ( Line level, or Mic level)
- 1/8” TRS Stereo Auxiliary Input
- Switchable Phantom Power for each input
- Switchable 100 Hz Low Cut lters for each input
- Dual 9V easy access Battery compartment
- Level controls for each channel
- 1/8” (3.5mm) Headphone/Earphone Output with Level control
- 18 hour battery life (with 2 condenser mics using phantom power and head
phones attached, constant use).
- Rolls PS27 external power supply included
QUICK START GUIDE
For those familiar with ENG or eld 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 connector.
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 eld.
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.

device in your signal chain (usually a recording device of
some kind), also via balanced XLR cables.
For monitoring external signal sources, connect a stereo
(Tip-Ring-Sleeve) plug to the Aux Input.
