72 Main Functions for the Graphic EQ and Shelving Equalizersi. To adjust the system to help reduce feedback, a normal technique is to turn themain system up to the point of feedback and then adjust the EQ sliders individual-ly to determine which frequency band will reduce the potential of feedback. Whenthe specific frequency band is isolated, set it to about -3 to -5 dB. Usually only 2or 3 bands can be reduced before the feedback reduction process begins to affectthe 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 conjunc-tion with the 9-band graphic. Yorkville engineers have developed this technique toprovide you with greater tone shaping capability. This allows the graphic equalizerbands frequencies to be spaced at closer intervals, which mean better selectivity forfeedback reduction and sound shaping. You may want to turn up the Lo and Hi con-trols to give the system a more HiFi sound when you’re playing at lower volumes. Athigher volume levels, you may need to turn these controls down, this will help maxi-mize the volume and tighten up the sound.iii. The third use of the graphic equalizer is to adjust the sound character for artisticreasons. The frequencies are adjusted until the sound feels best to the musicians.M810/M1610 Rear Panel1. Power AmplifiersEach of the M810/M1610 dual power amplifiers has two ¼-inch jacks and 1 Speakonjack for speaker connections. The power amplifiers are designed to provide full power intoa 4-ohm load. Connecting two 4-ohm speakers (2-ohm load) to either AMP A or AMP Bwill 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 theM810/M1610, this may cause the power amplifier to overheat. The amplifier willstart to reduce its power output in order to keep running. In extreme cases it maybe forced to shut down. If the clip LEDs are illuminated continuously and the PowerLED is off, this will indicate shutdown. After the M810/M1610 cools down, operationwill be restored automatically This condition should not occur if adequate ventila-tion is provided at the back of the unit.2. Power Switch and BreakerThe Power switch and circuit breaker are located on the rear panel. If the circuit breakertrips during use, wait a few minutes (to cool), then push in to reset. The circuit breakercan trip if the amplifier is too heavily loaded with long periods of continuous tones (suchas feedback). If the circuit breaker trips immediately after being reset, take the unit toyour Yorkville dealer for service.CHANNEL B CHANNEL ASPEAKER OUTPUT SPEAKER OUTPUTPhantomPowerPOWERONCircuitBreaker DESIGNED & MANUFACTURED BYYORKVILLE SOUND • TORONTO, CANADAonoff120VAC60 Hz • 6.4 ATYPE:YS1032A-Z446A / 2.0800 Watts MAX@ 4 ohms(2 ohm min.)800 Watts MAX@ 4 ohms(2 ohm min.)2 x 8 0 0 W a t t P o w e r e d M i x e rS e r i e s 2DISCONNECT POWERBEFORE SERVICING!DEBRANCHER L’APPEREILAVANT D’ENLEVERLES COUVERCLES!THIS UNIT MUST BE GROUNDED!CET APPAREIL DOIT ETRE MIS Á TERRE!
