1. INTRODUCTION

Congratulations on your purchase of an Ashly MX-

206 stereo microphone mixer. In one single-space rack-mount

package we have combined the features, reliability, and sonic

performance you have come to expect from Ashly. This third

generation mixer adds a universal 100-240VAC 50/60Hz power

supply and a 3.5mm front panel stereo line input jack.

Other features include stereo, mono, and headphone

outputs, 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 microphone 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.

4.5 Stereo Line In

This control adjusts the level of the stereo line in signal from the RCA inputs on the back panel and the 3.5mm Stereo

Line In jack on the front panel. The Stereo Line In input signal should have a nominal level of -10dB.

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 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.

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-206 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 con-

sumption is 30 watts.

THIS APPARATUS MUST BE EARTHED
