For convenience, a table of the effects and their variables appear later in this manual and on the front panel of the M810/M1610. Parameters for each of the effects can be changed using the MODIFY control which is located next to the Selection control. For example, if a Hall reverb has been selected, the MODIFY control will let you adjust the decay parameter. Choosing the Chorus effect allows the chorus rate to be adjusted. Note: The signal sent from the internal Digital Effects Processor to the MON mix is independent from the MON send controls on the channel strips. When a channel’s EFX control routes a signal to the internal Effects processor and the MON level control (for that channel) is turned off, the channel’s wet effects will still be audiable in the monitor bus (if the EFX to MONitor return level is turned up). 2. Effects CLIP LED Situated to the right of the MODIFY EFX control, the CLIP LED indicates that the digital processor is receiving an input signal that’s too strong, resulting in distortion. For optimum performance, the CLIP LED should never flash. If there is clipping activity, turn down the channel EFX controls appropriately. Built in 9-Band Graphic Equalizer & Shelving EQs 1. General Each EQ consists of a set of +/-15dB range type controls. In the M810/M1610 there are nine sliders for each channel, each one operating over a 2/3-octave portion of the midrange band of sound frequencies, as well as rotary shelving Bass and Treble controls. Note: Equalizers have an effect on the gain of the main system as well as its frequency response. Once adjusted, you may need to adjust the MAIN master level if the clip LEDs become too active.

To adjust the system to help reduce feedback, a normal technique is to turn the main system up to the point of feedback and then adjust the EQ sliders individually to determine which frequency band will reduce the potential of feedback. When the specific frequency band is isolated, set it to about -3 to -5 dB. Usually only 2 or 3 bands can be reduced before the feedback reduction process begins to affect the sound quality. ii. To adjust for deficiencies in the speaker system’s high frequency and bass response, the M810/M1610 also has a 2-band rotary shelving equalizer. These work in conjunction with the 9-band graphic. Yorkville engineers have developed this technique to provide you with greater tone shaping capability. This allows the graphic equalizer bands frequencies to be spaced at closer intervals, which mean better selectivity for feedback reduction and sound shaping. You may want to turn up the Lo and Hi controls to give the system a more HiFi sound when you’re playing at lower volumes. At higher volume levels, you may need to turn these controls down, this will help maximize the volume and tighten up the sound. iii. The third use of the graphic equalizer is to adjust the sound character for artistic reasons. The frequencies are adjusted until the sound feels best to the musicians. M810/M1610 Rear Panel 1. Power Amplifiers Each of the M810/M1610 dual power amplifiers has two .-inch jacks and 1 Speakon jack for speaker connections. The power amplifiers are designed to provide full power into a 4-ohm load. Connecting two 4-ohm speakers (2-ohm load) to either AMP A or AMP B will not harm the M810/M1610 but the maximum power output may be reduced. WARNING: Do not obstruct the flow of air around the vents on the rear of the M810/M1610, this may cause the power amplifier to overheat. The amplifier will start to reduce its power output in order to keep running. In extreme cases it may be forced to shut down. If the clip LEDs are illuminated continuously and the Power LED is off, this will indicate shutdown. After the M810/M1610 cools down, operation will be restored automatically This condition should not occur if adequate ventilation is provided at the back of the unit. 2. Power Switch and Breaker The Power switch and circuit breaker are located on the rear panel. If the circuit breaker trips during use, wait a few minutes (to cool), then push in to reset. The circuit breaker can trip if the amplifier is too heavily loaded with long periods of continuous tones (such as feedback). If the circuit breaker trips immediately after being reset, take the unit to your Yorkville dealer for service.
