Congratulations on your purchase of an Ashly
MX-206 stereo microphone mixer. In one single-space
rack-mount package we have combined the features, re-
liability, and sonic performance you have come to expect
from Ashly. This second generation mixer is similar to
the MM-106, except that where the MM-106 had only
one main output, the MX-206 has stereo, mono, and ste-
reo headphone outputs, each with its own level control.
Other features include a 20dB input pad on each
channel, switchable +48V phantom power, up to 60dB of
mic preamp gain (84 dB total!), and concentric level and
pan controls on each input channel.
Ultra low-noise summing amplifiers combine the
channel signals for the main outputs. Two 5-segment LED
arrays monitor stereo outputs. Stereo line level outputs
on 1/4" connectors, a transformer isolated 600 ohm mono
output on an XLR connector, and tape/CD inputs and
outputs on RCA connectors come as standard equipment.
Ashly still uses professional quality 16mm metal shaft
potentiometers on all controls for greater accuracy and
long life. Input isolation transformers are not available
on the MX-206.
4. CONTROLS (see next page)
4.1 Input dB (Gain)
This 3-position slide switch sets the operating level of the microphone preamp. Best signal
to noise ratio is obtained with higher gain settings, however it is important to leave enough headroom
(20dB) to prevent clipping. The numbers -20, -40, and -60 refer to the nominal level of the micro-
phone signal applied to the input. In other words, more gain is needed for a weak -60dB signal than
for a stronger -20dB signal, so as the switch is pushed further to the right, more gain is applied in the
mic preamp circuit. The center position (-40) is a good starting point for most applications. Note:
The Input Gain switch increases or decreases by 20dB increments. To avoid system feedback and
possible driver or hearing damage, turn down the channel level control before adjusting the gain,
then slowly increase level control to suitable setting.
4.2 Input Level
This inner concentric control determines the mix level of its respective channel. If you have
insufficient signal with the level fully turned up, change the Input dB (gain) switch of that channel to
a higher setting (turn down level first).
4.3 Input Pan
This outer concentric control determines the stereo position of the signal.
4.4 Clip
Each input has a red LED which will illuminate when either the mic preamp or input level
circuit pass a signal which is 3dB below clipping. If the level control is turned off and the LED is still
flashing, reduce the Input dB (gain) switch.

2. UNPACKING
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 ship-
ping carton and all packing materials , as they were care-
fully designed to reduce to minimum the possibility of
transportation damage should the unit again require pack-
ing 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.
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 avail-
able for inspection by the carrier. Save all packing mate-
rials until the claim has been settled.
3. AC POWER REQUIREMENTS
The MX-206 mixer will perform normally from
93 to 125 volts AC, 50-60Hz (some export models are
wired for 240 Volts and are labeled accordingly). 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
15 watts.
