MX-508 Front Panel

Input Level (Gain) - Sets the operating level of

the Mic preamp and Line Input. It is desirable to

set the Gain control as high as possible while

still leaving enough headroom to prevent

distortion.

Mic-Line Switch - Switches between the XLR

microphone input or the 1/4" line input jack as

the signal source. It can also serve as a

"channel mute" when switched to an unused

input.

Channel Clip Indicator - This peak indicator

monitors all level critical points in the input

channel and illuminates if any of them reach

levels within 3 dB of clipping.

Equalization - EQ consists of a high shelf

control at 15KHz (middle of shelf), a sweepable

mid control, and a 70Hz low shelf control. The

mid control is sweepable from 140Hz to 8KHz

with a bandwidth of approximately 1 octave.

Aux Sends - This pair of level controls adjust

the feed to monitors or effects units. Aux 1 is

factory preset to pre-fader, pre-EQ, while Aux 2

is post-fader, post-EQ. Both Aux sends can be

internally switched to pre or post fader/EQ.

Level and Pan - This concentric pair of

controls adjusts the level and stereo position of

the channel in the mix.

Aux Master Sends - These controls adjust the

overall gain of the output stages for the Aux 1

and Aux 2 outputs.

Aux Master Returns With Pan - These

controls adjust the returning signal from effects

units or auxiliary inputs to the Left and Right

outputs. Return 1 is stereo and return 2 is

mono. If only the right connection to return 1 is

used, this return will function as mono with pan.

Tape/CD Input and Send - Adjusts the

Tape/CD input to the Main Stereo outputs. The

outer concentric control labeled "To Aux 1"

sums the stereo Tape/CD signal to mono and

applies it to the Aux 1 Master group (pre-fader)

for use with monitors or effects.

10. Output Meters - A pair of peak reading 10

segment LED meters are used to indicate

output level. Green < 0 VU, Yellow >0 VU, and

Red = clipping. This meter pair is switchable

between the Main Left and Right, or the Aux 1

and 2 outputs. The red clip LED's will illuminate

if the summing amplifiers are clipping even if

the main output controls are off. Note: The

output meters are accurately calibrated to the

transformerless output levels, but not

necessarily the transformer-balanced outputs.

11. Main Output Level - These controls determine

the level of both transformer balanced and

transformerless output stages for the Main Left

and Right outputs.

12. Main Output Mutes - Switches off both the

transformer-balanced outputs as well as the

1/4" stereo outputs, indicated by the red LED

near the switch. The headphone and metering

functions continue uninterrupted.

13. Phantom Power Switch - This front panel

switch enables the +48 Volt phantom power for

condenser microphones. One switch controls

all the inputs. If you have both condenser and

dynamic microphones, the phantom power will

not affect the operation of the dynamic mics.

14. Mono Output Level - This control adjusts the

level of the summed mono output. It is

completely independent of the Main Left and

Right masters.

15. Headphones Level - This control adjusts the

level of the designated output signal (Mains or

Aux) to the headphone jack.

16. Meter/Phones Select - This switch selects

either the Main Left/Right outputs or the Aux

1/Aux 2 outputs to the LED meters and the

headphone jack.

17. Headphone Output - This front panel 1/4" TRS

connector feeds a standard set of stereo

headphones. A selector switch that also

controls the level meter allows monitoring the

main or Aux outputs.
