Yorkville Sound YS 1088 manual General Operating Instructions, Micromix

MICROMIX

Keep the Main Speakers

between mics and audience

to minimize feedback

DO NOT place Main Speakers in back of the stage!!

General Operating Instructions

1.Connect the AC power cord to a 120 Volt AC grounded power outlet (220 to 240 Volts in export units).

2.Turn the MAIN and MON master controls to 0 initially, then switch on the Power.

3.You can connect low-impedance microphones to the 3-pin XLR type MIC inputs.

4.Connect high-impedance mics or mono line-level signal sources (mixer line outputs, keyboards etc.), to the ¼-inch balanced LINE IN jacks on channels 1-2, 5/6 and 7/8. Connecting more than one signal source to both XLR and ¼-inch inputs is not recom- mended; this includes stereo sources (if you try to connect a stereo source to a mono channel using a Y-adapter, you may get distortion). The ¼-inch channels 3 and 4 are optimized for musical instruments and are not balanced.

5.Connect stereo sources (CD players, tape decks, stereo keyboards etc.) to chan- nels 5/6 or 7/8 via the stereo ¼-inch balanced LINE IN type inputs. Once again, connect only one signal source per channel, and use shielded patch cords for all pre-amp connections. If a monitor send or EFX send is not required use the Tape/CD input for your stereo source.

6a. Use 18-gauge (or heavier) speaker cables, using shielded patch cords to connect speakers will waste power by heating up. Connect one or two 8-ohm PA speakers to the SPEAKER outputs on the rear panel.

Note: To deliver maximum power to a pair of 4-ohm PA speakers, connect only one speaker to each amplifier.

6b. If you are using a separate power amplifier for the stage monitor speakers, connect the main speakers (as in #6, above) and run a shielded patch cord from the Post- EQ Mon Out jack to the input of the monitor power amp. If you are using a sepa- rate graphic equalizer for the monitors run a shielded patch cord from the Mon Out jack to the input of the EQ. Then, another one from the EQ’s output to the input of the monitor power amp.

7.Position your main PA speakers at the front of the stage, pointing directly at the audi- ence. Position your monitor speakers on the stage floor; preferably to one side of the mic stands, pointing up at the performer. Try to use cardioid or uni-directionalmics to help reduce the threat of feedback through the monitors (avoid having the back of the mic pointing directly at the speakers).

8.During a sound check and with the band playing, make the following control adjustments:

i.On mono channels, you can use the LEVEL control to set the channel volume level.

ii.Set the channel Lo, Mid, and Hi EQ controls at center. Set the channel LEVEL, MON, and EFX controls to seven. The Graphic EQ sliders and rotary shelving con- trols should be set at the center position at this point as well.

iii.Turn the MAIN and MON Master controls up to give the desired volume, the MAIN EFX return to around 7. Effects in the monitors tend to increase the possibility of feedback so if the band insists, set the MON EFX return to 5.

iv.Adjust the channel MON control/s to give each performer the desired volume levels. Use the MON master control to adjust the overall monitor level.

v.Use the channel LEVEL control/s to balance each channel’s volume level through the main PA speakers.

vi.Turn up the EFX controls on those channels requiring the selected Digital Effect. Typically, the lead and harmony vocal channels would be good candidates for effects. Reverb can be used on other channels or on recorded music, but should be used sparingly.
