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 appli-
cations engaging the Low-Cut lter is benecial, since little usable audio informa-
tion 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 rib-
bon microphones since an improperly wired cable can permanently damage the
microphone.

QUICK START GUIDE
For those familiar with ENG or eld mixers, this guide highlights basic functionality to
begin operating your MX410.
page 5 page 2
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 PS27s) 12-15 VDC to the MX410 DC Input connector.
2. Press in the POWER button.
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.
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 youre 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.
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.
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.
POWERING
We recommend using 9V alkaline type batteries, however Lithium or NiMH bat-
teries work as well.
For AC power, Rolls provides the model # PS27s 12-15 VDC supply to power the
MX410.
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.
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 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.
