Bedienelemente Frontseite (Forts.)

Each of the three front inputs provides a 3 band equalizer

(4), "LOW, MID and HIGH" and a volume level control (5).

Located right from the volume controls is the 5-position

source select switch (6) (SELECT). With this rotary knob you

easily can select any of the 5 RCA stereo inputs on the rear

side of the mixer, labelled AUX1 to AUX5. Typically these

inputs are used to connect CD/MP3 player, cassette player,

tuner or similar devices. Right of the source selector knob

you will find the volume control (7) for the selected source.

In the middle of the front panel you surely will see the pro-

tection plate, covering the 7 band equalizer. Reason for this

cover plate is to protect the equalizer settings made by an

acoustic engineer after calibrating the complete system.

If you may want to make your own sound adjustments,

and no calibration settings by

an acoustical expert must be

protected against unwanted

changes, feel free to remove

this metal cover plate. The gain

range of the equalizer is limited

to ± 6 dB by intention in order

to avoid extreme setting which

may result in an unwanted

"twisted" frequency response

and also may cause damage to

the system or components.

Gastro-Mixer GMX-2500

Operation Manual

On the right hand side of the GMX-2500 you will see the

output volume controls, one for the "MASTER" (9), the main

stereo output, and two smaller control knobs (8) for adjust-

ing the level of the two mono zones. For example the

stereo main output may be used in a pub or bistro to drive

the main loudspeakers, a zone output for the washrooms/

hallways and another one for separate smaller room. The

balanced XLR output jacks for the mentioned different

PA areas are located on the rear side. Above the "MASTER"

volume control you see a row of three LED indicators (10)

for power on, signal presence and for the limiter activity.

Limiter: Located on the right bottom side of the front

panel you see two recessed con-

trols for the limiter, one is the

on/off switch and the upper is the

screwdriver adjustable setting

for the limiter attenuation level.

The limiter is an important tool

to keep the sound pressure level

(SPL) within a prefixed maximum,

for example if government rules

do not allow SPLs above a cer-

tain maximum level. With this

limiter you can rest assured that this maximum level is

not exceeded–and you even can have this maximum level

measured and calibrated by an acoustic engineer and have

it officially sealed. The output level of the GMX-2500 may

be attenuated up to 30 dB. Last not least above the limiter

section you may have already noticed the "POWER" switch.
