INSTALLATION INSTRUCTIONS
MODEL MX-8 MIXER
Use this product according to this instruction manual. Please keep this instruction
manual for future reference.
GENERAL:
The MX-8 Mixer is an eight channel audio mixer designed to drive power amplified speakers in a telephone paging application or as
the input mixer for a commercial PA system. The MX-8 offers a choice of ten different inputs: five low impedance microphone
inputs, one telephone paging input, three high impedance auxiliary inputs and one PATCH IN input. The MX-8 allows eight of these
inputs to be used simultaneously: four microphone inputs, a choice of a telephone paging input or a fifth microphone input, and three
auxiliary inputs.
The front panel of the mixer features individual input level controls; as well as, MASTER gain and TREBLE / BASS controls, LO
CUT horn protect switch, LIMITER (ALC) ON/OFF switch, power ON indicator, INPUT PEAK indicator for the eight input
channels, and an OUTPUT PEAK indicator.
A built-in LIMITER circuit compensates for the varying voice levels and paging styles of the people who have access to telephone
paging or a microphone input. The LIMITER maintains rated output without distortion when input level exceeds rated input by as
much as 20dB. The LIMITER circuit affects only the MIC and TEL inputs.
Note that (AUX 1) auxiliary input (i.e., background music, tone generator, etc.) will automatically be soft muted whenever a
telephone page or a microphone page is generated. After completion of the page, the music will return to its original level.
On the rear panel, there is a power ON/OFF switch with a switched auxiliary AC receptacle, as well as a MIC 5/TEL select switch
and a PRE/POST EQ select switch for the LINE OUT.
All inputs and outputs are connected to the rear panel. Screw terminals are used for the Microphone and Telephone Inputs. Phono
jacks are used for auxiliary inputs, LINE OUT, TAPE OUT, PATCH OUT and PATCH IN.
The mixer operates from 115VAC, 60Hz and has a power consumption of less than 25 watts. There is no external fuse or circuit
breaker. IN THE EVENT THE MIXER DOES NOT POWER UP, HAVE THE TROUBLE INVESTIGATED BY AN
AUTHORIZED SERVICE TECHNICIAN OR RETURN UNIT TO FACTORY.
