CHANNEL CONTROL SECTION:

1. PEAK LED INDICATORS & TRIm CONTROL -

PEAK INDICATORS - These LED indicators will “light” when the input signal reaches 5db below the channel’s clipping point. If the LED “lights” more then usual, you should use the TRIM CONTROL to decrease the input level of the channel. If this does not work, reduce the output level of the connected source.

TRIm CONTROL - This adjustment is used to adjust the audio source signal input gain for a channel.

The best S/N and dynamic range balance will be reached if you adjust the TRIM CONTROL so that the

PEAk INDICATORS “light” occasionally.

Channel Sensitivity”

MIC input sensitivity is between +6db and -50db.

Line input sensitivity is between +14db and -30db.

The Mono/Stereo Combo input channel sensitivity is between +20db and -20db.

2. HPF (HIGH PASS FILTER) BUTTON - This button toggles the HPF (Hight Pass Filter) on or off. To turn the HPF on press the button in. The HPF cuts frequencies below 75Hz.

4. AUX CONTROLS - The AUX knobs control the signal level that the channel sends to AUX bus.

5. PRE/POST BUTTON - This button determines if the AUX signal is Pre Fader (signal level is not affected by fader position) or Post Fader (signnal level is affected by the fader position).

6. EFX CONTROL - These knobs control the signal levels sent to the EFX bus. The channel signals mixed by this bus have their overall level set by the MASTER EFX SEND control to the EFX jack located on the front top panel. Since the control is place after the channel fader, the signal level will be affected by the channel fader’s setting.

NOTE: The Effect bus signal is also fed into the internal DSP (digital signal processor).

M1224FX CHaNNEL CONTROLS aNd FUNCTiONS cont.

7. PAN/BALANCE CONTROL -

PAN (mono Control) - This control pans the channel signal across the master L and R buses, therefore determining the ideal position of the sound from that channel.

EXAmPLE: If the PAN control is set all the way to the left, the sound from that channel will only be projected from the left speaker only. Same goes for the control being set all the way to the right, only from the right speaker.

BALANCE (Stereo Control) - This control lets you adjust the balance of the L/R position, of the stereo input signal. Turning this knob to the left moves the source signal towards the MAIN MIX L bus, turning the knob to the right sends the signal towards the MAIN MIX R bus.

8. mUTE/ALT 3/4 BUTTON - When the corresponding channels MUTE/ALT 3/4 button is not active

(depressed) the channel output will be sent to the ALT 3/4 output, and not the MAIN L/R output. The

ALT 3/4 bus gives you a second independent stereo sub mix with its own sub master stereo fader.

9. PFL BUTTONS - This button allows you to monitor the PRE FADER LEVEL input signal through headphones or the control room outputs. When the button is NOT pressed the channel signal will be sent to the PFL bus.

10. CHANNEL FADERS - Thes faders are channel’s main level control. These fader’s control the signal level sent from the channel to the master mixing, group outs, and effect buses. The settings of the input channel faders affect the mix or the sound level balance between the instruments or other sources connected to the inputs. When a channel is not being used, the fader should be set at the minimum position to prevent any unwanted noise added to the main signal.

M1224FX CONNECTORS

- Always use good quality twin screened audio cable. Check for instability at the output.

- Always connect both conductors at both ends, and make sure that the screen is connected only at

one end.

- Do not disconnect the mains earth from each piece of equipment. This is needed to provided both

safety and screen returns to the system star point.

- Equipment which has balanced inputs and outputs may need to be electrically isolated from the

equipment rack and/or other equipment, to avoid earth loops.

It is important to remember that all equipment which is connected to the mains it a potential source of hum and interference and may radiate both electrostatic or electromagnetic radiation. In addition, the mains will also act as a carrier for many forms of RF interference generated by electric motors, air-conditioning units, hyristor light dimmers etc. Unless the earth system is clean, all attempts to improve hum noise levels will be ineffective. In extreme cases there will be no alternative but to provide a completely separate and independent ‘technical earth’ to replace the incoming ‘noisy earth’.

However, always consult your local electricity supply authority to ensure that safety regulations are not being infringed.

M1224FX CLEaNiNG

Dust will settle in the fader track overtime dust can cause a popping noise on the fader. To prevent this cover you mixer. If the mixer has been unused for over a month or more move you faders up and down a couple of times this will move most of the settle dust from the fader track. Do not eat, drink, or smoke over you over or near the mixer.

Don’t use spray cleaners. Use compressed air or a vacuum with a brush accessory.

Cleaning frequency depends on the environment in which the mixer operates (i.e. smoke, fog residue, dust, dew).

M1224FX TROUBLESHOOTiNG

Trouble Shooting: Listed below are common problems you may encounter, and solutions.

I can’t hear the source from a channel thru the main mix

Check the trim knob, fader, and output volume on your source.

Check the Mute button, or make sure your sub groups are assigned to the mains.

Check you connection from the source to the mixer.

Try the same connection on a different channel with the same settings.

I hear noise in mix

Check your power a 60Hz hum, could come from ungrounded equipment.

Turn all the faders down one at a time and the stereo return knob. If the noise goes away it’s that channel or the source. Disconnect the source from the mixer bring up that fader if the noise is gone it your source, If it is the source try bringing down its out put volume.

I have no power

Make sure your power supply is properly hooked up to the unit.

I can’t hear the mix on my headphones or my control room monitors

Check the phones / control room knob, Select the proper source.
