1. INTRODUCTION
2. UNPACKING
Congratulations on your purchase of an Ashly MX406 stereo mic/line mixer, a professional, studio quality solution to everday mixing needs. MX-406 features include six
channels of mic or line inputs with mic input pad, TRS insert
points, and +48V phantom power. Each channel has up to
60dB input gain, separate treble and bass controls, an aux
send control, level, and a stereo pan control. A stereo line
input is provided for a stereo program source such as tape,
CD, or MP3 player. Outputs include aux master, stereo line
out (pre-master), stereo left and right, transformer balanced
mono out, and stereo headphones. A full 11 segment LED
array indicates stereo output level.
As a part of our system of quality control, every Ashly
product is carefully inspected before leaving the factory to
ensure flawless appearance. After unpacking, please inspect
for any physical damage. Save the shipping carton and all
packing materials , as they were carefully designed to reduce
to minimum the possibility of transportation damage should
the unit again require packing and shipping. In the event that
damage has occurred, immediately notify your dealer so that
a written claim to cover the damages can be initiated.
Stereo main outputs use 1/4" jacks, stereo line input
and line out use RCA connectors, and there is an additional
3.5mm jack on the front panel for stereo line in. A transformer
isolated 600 ohm mono output uses an XLR connector. Ashly
mixers still use professional quality 16mm metal shaft potentiometers for greater accuracy and long life and of course, Ashly
products come with a worry-free five year warranty.
The right to any claim against a public carrier can
be forfeited if the carrier is not notified promptly and if the
shipping carton and packing materials are not available for
inspection by the carrier. Save all packing materials until the
claim has been settled.
3. AC POWER REQUIREMENTS
The MX-406 mixer will perform normally from 100
to 240 volts AC, 50-60Hz. Use only properly grounded AC receptacles. To reduce the risk of ground loop hum, use a central
point for system AC power distribution. Power consumption
is less than 30 watts.
WARNING:
THIS APPARATUS MUST BE EARTHED

Operating Manual -MX-406 Stereo Microphone/Line Mixer
4. FRONT PANEL CONTROLS
4.1 Input Gain
This three position switch sets the operating level of
the microphone and line input preamp. The corresponding
switch values -20db, -40dB, and -60dB refer not to the actual
gain, but rather to the expected nominal input signal strength.
Best signal to noise ratio is obtained with higher
gain settings. It is therefore desirable to set the gain control
as high as possible while still leaving 20dB of headroom for
signal peaks. Line level inputs (1/4" jack) will likely use a
setting of -20dB, while mic inputs generally require a setting
of -40dB for close mic applications, and -60dB for quieter
signals. If a channel's clip LED is blinking, first turn down
that channel's level control. If the clip LED is still flashing,
turn down the input gain.
4.2 Clip
Input Clip LEDs are peak sensitive and monitor all
critical points within the input channel. The clip LED turns
on whenever any portion of the audio path within the input
channel reaches a level 3 dB below actual clipping. Clipping
in the MX-406 occurs at +20dB.
4.3 Treble/Bass
This concentric knob is used for broad EQ changes
to each input channel. Channel EQ consists of a high shelf
control (treble) at 4KHz, and a 250Hz low shelf control (bass).
EQ boost or cut is ±12dB.
4
4.4 Aux
The aux send is an additional level control used to send
signal from each input channel to monitors, an effect unit, or
another mix. The aux master output combines all six channel's
aux level signals. The aux control is factory set to pre-fader,
pre-EQ, but can be internally switched to post-fader, post EQ.
To make this change, refer the following procedure to a qualified service technician:
Unplug the unit's AC power cord from the outlet.
Remove the bottom cover which is fastened by seven 6-32
screws. Locate the 3 pin header labeled AUX at the middle of
the back edge of the front portion of the channel circuit board.
Remove the shunt bar from the "Pre" position indicated on the
circuit board legend and place the shunt on the "Post" position.
4.5 Level and Pan
This concentric knob adjusts the level and stereo
position of each channel. If a channel's level control is always
turned up to 9 or more, try increasing the gain first. Conversely, if the level control is consistently turned down to 1 or
less, decrease the gain setting first. Remember that the gain
setting should be set as high as possible while still allowing
20dB of headroom.
4.6 Stereo Line In
This control adjusts the level of the stereo line input
RCA jack on the back panel, as well as the 3.5mm stereo line
in jack on the front panel. They can be used for tape, CD/
DVD, or MP3 player audio inputs, and can also be used for a
stereo effect return. Both inputs can be used simultaneously,
but there is only one level control. For expanding the channel
Operating Manual - MX-406 Stereo Microphone/Line Mixer
capacity of the MX-406, the stereo line input can be used as
stacking inputs for supplementing the MX-406 with another
mixer, such as an Ashly LX-308 stereo line level mixer.
4.7 Aux Master Output
This control adjust the level of the aux master ¼"
jack output, which gets it's signal from the six aux level
controls on the input channels. It is used for an effects unit
send, or can drive a power amplifier for monitors or an extra
loudspeaker zone.
4.8 Main Outputs
These two controls determine the signal level to the
¼" jack left and right outputs. They are used to drive power
amplifiers for the main loudspeakers, or to connect to a stereo
recording device.
4.9 Mono/Phones Output
4.10 Output Meters
A pair of peak reading 10 segment LED meters are
used to indicate stereo output level in VU. 0 VU is equivalent
to +4 dBu (1.228Vrms).
Green LED's are used below 0 VU, yellow above
0 VU and two red LED's indicate clipping. The clip LED's
turn on 3dB below actual clipping, detecting excessive signal
level on any critical audio path within the master section. If
all outputs are turned down and there is still clipping, then one
or more inputs must be turned down.
4.11 Phantom Power LED
The phantom power switch is on the back panel.
When the switch is pressed in, the LED is lit and +48VDC
is applied to all six mic inputs for use with condenser microphones. If there is a mix of both condenser and dynamic
microphones, the phantom power will not affect the operation
of the most dynamic mics.
Thinner concentric knob adjusts the level of the
summed mono output. It is completely independent of the main
left and right master controls. In other words, changes to either
left or right output level will not affect the mono output level.
The outer concentric knob adjusts the level of the
stereo signal to the headphone jack. Headphones should have
an impedance of 600 ohms or greater, or signal distortion may
result.

Operating Manual -MX-406 Stereo Microphone/Line Mixer
5. CONNECTORS AND CABLES
The MX-406 mixer is fitted with five types of audio
connectors: 3-pin XLR type male (mono output), 3-pin XLR
type female (mic inputs), 1/4" tip-ring-sleeve (TRS) phone
jack, 3.5mm jack (stereo line in), and RCA jack. Certain 1/4"
jack connections may use an unbalanced mono plug, which
is also shown.
Two-conductor (twisted pair) shielded cable is
best for all XLR type connections. Belden No. 8412 or its
equivalent is an excellent cable due to its heavy construction.
This type of cable should be used for all portable applications. Snake cables containing multiple shielded pairs must
be handled very carefully because the leads tend to be fragile,
and a broken conductor is difficult to repair.
If low level and high level lines are run parallel for
long distances, crosstalk may occur. In fact, the crosstalk (signal leakage between cables) can cause an electronic feedback
loop, oscillation, and possibly damage to the equipment. To
minimize crosstalk, physically separate low level (microphone)
cables from speaker cables by the greatest feasible distance.
At any point where cables meet, run low level cables perpendicular to high level or speaker cables. If low and high level
or speaker cables must be run parallel and in close proximity
to one another, they should be bundled separately. In a permanent installation, avoid running speaker cables and mic cable
through the same conduit pipe.
6. REAR PANEL FEATURES
6.1 Microphone Input
The MX-406 microphone input is an active balanced
type with a nominal impedance of 1200 ohms. Its noise performance is best with a 200 ohm microphone. The Mic input
connector is a standard 3-pin XLR female with the shield on
pin 1, the (+) in-phase connection on pin 2, and the (-) out-ofphase connection on pin 3.
6
Operating Manual - MX-406 Stereo Microphone/Line Mixer
6.2 Input Pad
6.5 Stereo Line Input
The input pad is a 20dB attenuation switch on the rear
panel for use with the XLR microphone inputs. It should normally be left in the "out" position for best signal to noise ratio
and should only be used when the input is being overdriven
with the gain control at its minimum setting.
The stereo line RCA inputs, and the front panel stereo
line in 3.5mm jack, have a nominal operating level of -10dBu to
match most consumer audio sources. This signal is controlled
by the Stereo Line Input dial on the front panel. This input is
also used as a stereo effects return, or as a stacking input for
adding additional mixers.
6.3 Line Input
The line input is a standard 1/4" TRS active balanced
type found in the same "combo jack" connector as the mic
input. The line input balanced impedance is 20KΩ. It will
accommodate a wide range of input levels.
6.4 Channel TRS Insert
A channel TRS insert patch point allows a device
such as a remote level controller, graphic equalizer, noise
gate, compressor/limiter, or direct out recording device to be
used with one or more input channels.
The MX-406 TRS insert jacks use the tip for output
and ring for the returning input. These signals will be unbalanced, so cable length should be at a minimum to maintain
low noise.
To use the TRS insert as a Direct Line Output (pre
EQ) for recording, you must make a special cable with tip and
ring connected at the MX-406 end and a tip-sleeve mono plug
at the other end. Connecting tip and ring at the mixer insert
jack is necessary for uninterrupted signal within the mixer
when using direct line outputs.
6.6 Stereo Line Out
The stereo line outputs are nominal -10dBu "premaster", so they are not affected by the settings of the main
Left/Right output controls. These outputs would be used for
making a pre-output fader recording off of the stereo mix, or
for stacking the MX-406 stereo output into another mixer.
6.7 Aux Master Output
The 1/4" jack aux master output is used to drive a
monitor or zone amplifier, effects processor, recording device,
or any function which requires level control independent from
the main stereo mix. It is pseudo-balanced, which means that
while it is a single ended signal, it has balanced impedance
for low noise when driving an active balanced input circuit
over a long distance.
6.8 Mono Output
The XLR mono output combines the left and right
stereo signals (pre output fader), and uses an isolation transformer capable of driving 600 ohm lines. Pin 1 is ground, pin
2 is (+), and pin 3 is (-). This signal is determined by the mono
output level control, with a nominal operating level of +4dBu.
7
Operating Manual -MX-406 Stereo Microphone/Line Mixer
(Mono Output, cont.)
Note: The mono transformer-balanced output is designed to drive up to +24dBu into 600 ohm loads. Because of the
nature of an output transformer, the output level increases as the impedance of the terminating load becomes higher than 600
ohms. Whereas a "direct-coupled" output stage like that of the right and left outputs will not change as the load changes, any
transformer used in an audio path is affected by its termination impedance. Since line level inputs on audio devices are typically 10KΩ or higher, expect a slight increase (2.5dB) in output level when driving conventional active 10KΩ inputs with the
transformer outputs.
6.9 Stereo Outputs
The 1/4" jack stereo right and left outputs are controlled by the left and right master. They are pseudo-balanced TRS
jacks with a nominal operating level of +4dBu into any load, and are capable of driving long lines.
6.10 +48V Phantom Power Switch
This switch applies +48VDC to all six XLR mic inputs to power condenser microphones. Phantom power will not
affect most dynamic mics, which may be used along with condenser mics.
7. TYPICAL
APPLICATIONS:
7.1 Small Sound Reinforcement System:
In the setup shown here, the MX-406 is used
to mix typical sound sources that might be
found in a church, small club, school theater
or similar environment. Four of the input
channels are used for vocal microphones,
while the remaining two channels are used
for stereo accompaniment tracks. The stereo
line input is used for additional pre-recorded
music such as that of a movie soundtrack, CD
player, or MP3 player. Stereo line output
RCA jacks are used to record the event to
a cassette, video camera, or even a PC with
recording capabilities.
Stage monitors are fed using the aux mix
to the master aux output, and left and right
outputs drive the main speakers. The mono
output drives a 70 Volt distributed sound
system amplifier, used for plenum (ceiling)
speaker installations.

Operating Manual - MX-406 Stereo Microphone/Line Mixer
7.2 Meeting Room, Board Room, or Church Mixer Using Remote Control:
In this illustration, the MX-406 is interfaced with an Ashly VCM-88 eight channel remote level controller, allowing
the mixer to be operated from a distance by a non-technical person. Remote control of the VCM-88 is achieved through the use
of Ashly's RD-8 desk-top remote controller, RW-8 wall-plate version, or PC control using Protea System Software. The RD-8
and RW-8 use a single mic cable for control data, while PC control uses RS-232 serial communications. Remote control can
be located up to 1,300 feet from the main audio equipment rack.
8. TROUBLESHOOTING TIPS
8.1 No Sound
Check the AC power. Is the power switch on? Check the level meters. If they are operating, the problem is between
the mixer and the later components in the system. If there is no meter activity, check to see that you really have an input signal
and that it is on the desired channel.
8.2 Distorted Sound
Something is being overdriven in the signal path. If the clip indicators are active, reduce the channel gain and/or press
in the pad switch on the rear panel. There are many gain adjustments in the mixer itself and probably several others in other
system components which makes it possible to overdrive an input section and then incorrectly try to reduce the gain of the
output section. The best way to approach setting gains is to establish the operating level of input stages first by setting their
gain as high as possible but leaving about 20dB of headroom for loud peaks, then move on to set the master gain to produce a
good meter reading. Proceed to set the gain of equalizers, limiters, crossovers, and amplifiers following the mixer in the same
manner, always working toward the later stages of the system.
9
Operating Manual -MX-406 Stereo Microphone/Line Mixer
8.3 Excessive Noise
If the noise is in the form of hiss, the problem is usually due to an input stage set for insufficient gain and then compensating for it by increasing the level. Try increasing gain and reducing level. Also, check that the -20dB rear panel pad switch
is not unnecessarily enabled.
8.4 Excessive hum
This is usually caused by "ground loops" in the system wiring. A complex sound system with many sources separated
by significant distance and using several power outlets has many opportunities for this problem to occur. If possible, feed
everything in the system from one power source with a common ground. Use balanced input and output connections between
widely separated components.
If you need help, get in touch with your Ashly dealer or call an Ashly technical service representative.
