15、 direction of the Channel 1 slide fader. (17) The Channel 1 SLIDE FADER (17) controls the input level of this channel. 3. CHANNEL 2: The GAIN (11), HIGH (12), MID (13), and LOW (14) controls allow you to fully adjust the volume and EQ of the sound source. The Channel 2 REVERSE SWITCH (16) allows you

16、 to reverse the direction of the Channel 2 slide fader. (18 ) The Channel 2 SLIDE FADER (18 ) controls the input level of this channel. 4. EQ CONTROLS: There is Low, Mid and High equalization for each channel with an extremely wide range of adjustment. 5. INPUT ASSIGN SWITCHES: You can adjust the po

17、sition of the INPUT ASSIGN SWITCHES (21, 22) to move left to right, up and down, or at a 45 degree angle. Make these adjustments with the power OFF. 1) Remove the channel slide knobs, crossfader knobs and the 4 screws from the sides of the lower faceplate. Then remove the lower faceplate. 2) Remove

18、the 2 screws in the corners of the assign switch plate. Rotate the switch plate to the desired position, and replace the screws and tighten down. 3) To position the switch at a 45-degree angle, you need to reposition the switch on the assign switch plate. First, remove the 2 screws in the corners of

19、 the assign switch plate. Then, lift the switch plate up and remove the 2 smaller screws next to the switch. Rotate the switch plate to the right until the 45-degree holes align with the switch holes, replace the screws and tighten down. Replace the switch plate and tighten down. NOTE: Keep track of

20、 where you position the input assign switches. OPERATION 6.

21、adual and even. Move the channel slide curve switch to the 20 (center) position to make the increase in level less gradual as you move channel slide up. Move the channel slide curve switch to the 30 (bottom) position to make the increase in level even less gradual, especially at the top of the slide

22、. 7. CROSSFADER SECTION: The CROSSFADER (25) allows the mixing of one source into another. The left side of the CROSSFADER (25) is CHANNEL 1 and the right side is CHANNEL 2.
