M822FX 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.

M822FX 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).

M822FX 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.
