Connect the output of a CD player, MD player, and tape deck to the line input. wINPUT ASSIGN SWITCH Selects the input to be sent to each P

3、GM channel. ePGM TRIM VOLUME Adjusts the input level of each PGM channel. PGM LEVEL METER to indicate at about 0dB. rPGM BALANCE VOLUME Adjusts the stereo balance for each PGM channel. Can be used for adjusting the unbalanced stereo image. Clockwise rotation from center position increases the volume

4、 of R over L channel. A counter clockwise rotation increases the volume of L channel over R. tPGM ISOLATOR HI Adjusts the HI frequency level of each PGM. yPGM ISOLATOR MID Adjusts the MID frequency level of each PGM. uPGM ISOLATOR LOW Adjusts the LOW frequency level of each PGM. iISOLATOR ON/OFF SWI

5、TCH When set to OFF, a full range signal is transmitted regardless of the position of any isolator controls. oHI PASS FILTER SWITCH On each PGM is a Hi Pass Filter Switch. Pressing this switch activates the high pass filter and when on the indicator LED will illuminate. The cut off frequencies for t

6、his filter can be adjusted by the SWEEP volume rotary dial !1. If this switch is pressed simultaneously with the Low Pass Filter switch the resulting effect is a Notch Pass Filter. !0LOW PASS FILTER SWITCH On each PGM is a LOW pass filter switch. Pressing this switch activates the low pass filter fo

7、r that PGM. When on the indicator LED will be illuminated and this filter will remove sound frequencies below the cut off point. The cut off point can be adjusted by using the SWEEP volume rotary dial !1. If this switch is pressed simultaneously with the High Pass Filter switch the resulting effect

8、is a Notch Pass Filter. !1SWEEP VOLUME This rotary dial is used to adjust the filter cut off points on each PGM. A rotation to the left will result in a movement away from the High frequencies towards the Low frequencies. Vice versa a movement to the right will result in a movement away from the Low

9、 frequencies towards the High frequencies. !2C.F. ASSIGN SWITCH Assigns the signals from each of the PGM channels to either side of the crossfader or to MASRER OUT. There are three positions; A ?The PGM is sent to the A position or left position of the crossfader. MASTER ?The PGM is sent directly to

10、 the master out. B ?The PGM is sent to the B position or right side of the crossfader. !3CUE SWITCH Sends a signal from each PGM to the monitor section for headphone monitoring. When switch is on, an indicator lights up. !4INPUT LEVEL VOLUME Adjusts the Input level of each program. Typically this fa

11、der is set to a position of 7-8. This fader is user replaceable and may be changed easily by following this users guides instructions carefully. See HOW TO CHANGE THE FADER UNIT. *Replace this fader with a Vestax IF-500 replacement inputfader. PROGRAM SECTION 123 1410913 4567 11 8 12 RadioFans.CN 收音

When switch is on, an indicator lights up. !7CF CURVE VOLUME djusts the cro

13、ssfader curve. A clockwise rotation gives a sleep crossfade which is good for scratching and cutting. whereas a counter clockwise rotation gives a gentle crossfade, good for long running mixes. !8MASTER LEVEL METER The VU analog level meters indicate the L and R outputs. !9PGM LEVEL METER The LED ba

14、r level meters indicate the PGM channel. 0BOOTH MONITOR EQ VOLUME Adjusts the HI/MID/LOW frequencies for the BOOTH OUT. 1BOOTH MONITOR LEVEL VOLUME Adjusts the output level of BOOTH MONITOR. 2BOOTH MONITOR MUTE SWITCH This switch mute the signal being sent to the BOOTH OUT. 3ANTI PHASE ON / OFF SWIT

15、CH This switch is used to activate an antiphase effect on the Master Isolator Section. Essentially, an antiphase flips the isolator curve upside down on both the low and mid frequency ranges, which thereby creates a reverb type effect on the signal being outputted. 4MASTER ISOLATOR HI This rotary di

16、al section can be used to isolate the Hi frequencies on any MASTER SECTION input signal. 5MASTER ISOLATOR MID This rotary dial section can be used to isolate Mid frequencies on any MASTER SECTION input signal. 6MASTER ISOLATOR LOW This rotary dial section can be used to boost the Low frequencies on

17、any MASTER SECTION input signal. 7ISOLATOR ON / OFF SWITCH This switch is used to turn the Master Isolator Volume Section either on or off. When set to the OFF position the full range of input signal being sent to the MASTER section will be heard regardless of the position of the Master Isolator Vol

When the crossfader is set in the center position, both the left and right signals will be heard. This fader is user replaceable and may be changed easily by following this u

19、ser guides instructions carefully. See HOW TO CHANGE THE FADER UNIT. *Replace this fader with a Vestax CF-50 replacement inputfader.

20、SUB LINE SELECTOR Selects between MAIN MIC and SUB LINE input. #1MIC / LINE EQ VOLUME Adjusts the HI and LOW frequencies for the signal chosen by MAIN MIC / SUB LINE SELECTOR. #2MIC / LINE LEVEL VOLUME Adjusts the input level of the MAIN MIC or SUB LINE input. #3MIC / LINE CUE SWITCH Sends the signa

21、l from the MIC or LINE channel to the monitor section for headphone monitoring. When switch is on, an indicator lights up. #4SPLIT / STEREO SELECTOR When this switch is set to SPLIT, the master signal is always heard through the right ear-cup of the headphone. The signal selected by each CUE SWITCH

22、will be heard in the left ear-cup. This enables both programs to be monitored simultaneously, thus assisting in beat mixing. When this switch is set to STEREO no master output is heard in the headphones, and only the signal selected by each CUE SWITCH will be heard in both ear-cups. #5HEADPHONE EQ V

23、OLUME Adjusts the HI and LOW frequencies for Headphone monitoring. #6HEADPHONE LEVEL VOLUME Adjusts the headphone monitor level. #7PHONES JACK Use this jack to connect headphones.
