The unit should be connected to a standard 3-wire grounded electrical outlet supplying 100-240 Volts, 50-60 Hz. To reduce the risk of ground loop hum, connect all audio equipment to the same electrical power source. Removal of the ground pin is both unlawful and dangerous, as a potential shock hazard could result. Overall power consumption is less than 30 watts. NOTE: The power switch does NOT isolate the appliance from mains. Make sure the mains power socket or an alternative disconnect device is near by and easily accessible. When the product is connected to mains, the line-filter and the input of the fuse are energized.

Six input channels are used for microphones for vocal or instrumental pickup. The Tape/CD In and Tape Out provide feeds to and from a cassette deck or other recording/playback device for playback of recorded material, or for making a recording of the mix. The main PA power amplifiers (or any additional equalizers or electronic crossovers which may be used) are fed from the Stereo Output connectors, while a stage or control room monitor is fed from the Mono Output. Location Recording or Broadcast Mixing The MX-206 can be used to mix sources typically found in location recording or broadcast situations (mostly microphones). In this case, all six inputs are microphones, as would be used in a roundtable panel discussion. The Tape/CD Input receives the output of a cassette deck or other playback device, and the Tape Out provides a feed to a cassette deck or other recording device for making a recording of the mix. For live remote broadcast applications the transformer-balanced Mono Output connector can feed a suitable video, telephone or press-box interface. Submixer In Larger Sound System: The MX-206 can be used to provide a drum mix to the main mixer without tying channels on the main console. Up to eight mics can be "pre-mixed" in stereo, with all drum-specific gating, compression, and effects controlled directly by the drummer. Either the main OUTPUT or the SUB OUT connectors can be used to feed the mixed drum signal to the main mixer. If there is significant distance between the MX-206 and the "master" mixer, use the pseudo-balanced or transformer- balanced Main outputs for long cable runs. Copyright© 2006 – Ashly Audio Inc. Operator Manual – MX-206 Mixer Page - 9 Troubleshooting Situation Action No Sound Check the AC power. Is the power switch on and the front-panel LED illuminated? Check the level meters. If they are operating, either the problem is between the mixer and the later components in the system. If there is no meter activity, check to see you really have an input signal and that it is on the desired channel. Check that you have the master gain controls at the desired operating level. Distorted Sound Something is being overdriven in the signal path. If the clip indicators are active, reduce the channel gain controls and/or press in the pad switch on the rear panel. If the level meters are constantly in the red, reduce the Master gain and increase the gain of components following the mixer. There are many gain adjustments in the mixer itself and probably several others in other system components which makes it possible to overdrive an input section and then incorrectly try to reduce the gain of the output section. The best way to approach setting gains is to establish the operating level of input stages first by setting their gain as high as possible but leaving about 20dB of headroom for loud peaks, then move on to set the master gain to produce a good meter reading. Proceed to set the gain of equalizers, limiters, crossovers, and amplifiers following the mixer in the same manner, always working toward the later stages of the system. Excessive Noise If the noise is in the form of hiss, the problem is usually due to an input stage set up for low gain and then compensating by increasing the master gain. Check that the Pad switch is not enabled unnecessarily. Turn up the channel gain controls and reduce the master gain. Excessive Hum or Noise This is usually caused by "ground loops" in the system wiring. A complex sound system with many sources separated by significant dis...
