Ashly Mx–4066 User manual

5-Year Warranty Hand-built in

Webster, NY

The MX-406 is a rack-mountable six-input, stereo mic/line

mixer designed to be used in xed or portable installaons.

Each input will accept either microphone or line-level

signals. If microphones are used, a -20dB pad switch is

available. The microphone input has an ultra low-noise

studio-grade mic preamp with up to 60dB of mic preamp

gain. A three-posion switch allowing you to set input gain

for -20, -40 and -60dB is located on the front panel.

Each input has bass and treble shelving lters with

individual control of each lter. An Aux Send on each

input can be internally assigned pre or post level/EQ.

Level and pan controls complete each input.

Addional front panel controls include: Aux Master Out-

put, Le/Right Stereo Output, On/O Power switch and

3.5mm stereo line in jack on the front panel oers a conve-

nient input alternave for MP3 players and smartphones.

A Mono/Phones output control allows you to adjust the

mono output and stereo headphone output. The Stereo

headphone output jack is located on the front panel. Front

panel LED indicators include channel clip, Phantom power,

AC power and an 11-step LED output level meter.

Connecons on the rear panel include 1/4” TRS and XLR

jacks for each input, and an XLR transformer balanced

mono output.

The balanced stereo output jacks are 1/4” TRS.

Channel inserts are 1/4” TRS. Le and Right Stereo

Line Inputs (return) and Stereo Line Out use RCA

jacks. A switch turns +48V Phantom Power on or o.

Designed and built in the USA, the MX-406 has an

all-steel chassis, contains high-quality components

and has a ve-year warranty.

arChiteCt & engineering SpeCS

The unit shall be a six input stereo mixer having separate balanced outputs for both le and right channels. There shall be a transformer balanced mono-summed output with separate front

panel level control. Each input channel shall have level and stereo-balance controls on one concentric pot. An Aux send shall be on each channel factory wired pre-fader/EQ. The Aux send shall

be congurable for Pre/Post fader/EQ via circuit board jumper connecon. Each input channel shall have a two-band equalizaon control on one concentric pot located on the front panel. The

equalizaon shall consist of high and low shelving points being xed at 70Hz and 8kHz with a cut/boost range of +/- 12dB. Each input channel shall have 40dB of available aenuaon on the front

panel, as well as a 20dB mic input pad on the rear panel. Each input channel shall have an in/out insert point on a single TRS 1/4” phone connecon, and separate 1/4” TRS and XLR connectors

for line input and balanced microphone sources. Phantom power of +48VDC for each input must be available via a single rear panel switch. There shall be one Master Aux Output control provid-

ed on the front panel. A 1/4” TRS Aux Master Output Jack shall be located on the rear panel. There shall be an addional Stereo Line Input on back panel RCA jacks and a front panel 3.5mm ste-

reo phone jack with level control. Separate stereo RCA line outputs must also be provided. A TRS 1/4” Headphone Output and Level Control to monitor both Le and Right must be provided on

the front panel. Overall gain available from Mic Input to Main Outputs shall be 84dB, and the Mono Output level shall be +23dBu into 600 Ohms. There shall be an eleven stage LED ladder output

VU meter located on the front panel indicang signal levels from -21VU to +6VU and clip when the signal level is 3dB below actual clipping. Each individual channel shall have a clip indicator as

well. The mixer unit shall be no higher than two rack spaces and must be fully covered under a ve year warranty. The mixer shall have an internal power supply with the power switch located on

the rear panel. The mixer must be manufactured in The United States of America, with a shipping weight of 14 pounds. The mixer shall be the model MX-406, manufactured by Ashly Audio, Inc.
