5、l relevant to each PGM. yMID ISOLATOR This knob is used to adjust the MID frequency signal level relevant to each PGM. uLOW ISOLATOR This knob is used to adjust the LOW frequency signal level relevant to each PGM. iSCRATCH EQ This button is used to activate the scratch EQ feature (new) on this mixer

6、. The scratch EQ feature essentially disregards the manual isolator EQ setting and passes all signal feeds through a Mid Boost and Hi Boost EQ and Low Cut circuit (per PGM), which is designed to generate the best scratch EQ setting possible. oSCRATCH EQ INDICATOR This LED will be illuminated when th

7、e Scratch EQ feature i is on. !0PGM BALANCE This fader is used to adjust the stereo balance on each PGM. The PGM Balance can also be used to adjust an unbalanced stereo image. From the center position a movement to the right will increase the volume of the signal R over L and vice versa. !1CF REVERS

8、E SWITCH This switch is used to reverse the direction of the cross fader (CF) such that if reversed position 1 becomes position 2 and vice versa. When reverse mode is activated the CF REV LED 6 will be illuminated in the main LED section. !2MASTER LEVEL This knob is used to adjust the signal levels

9、from the Line Out connections found on the rear panel of this unit. !3STEREO/MONO SELECT SWITCH This switch is used to select either a mono or stereo signal output for the Line Out section. Regardless of your choice, the L & R levels will remain the same. !4BOOTH LEVEL This knob is used to adjust th

10、e level of output through the Booth section. !5MONITOR SELECT SWITCH This switch is used to select which type of monitor signal, either CUE or MASTER, is heard in headphones connected to this mixer. When set to CUE, both signals (including the EQ settings on each) will be heard. Using the CF Monitor

11、 Fader 9 will alter what is heard in the headphones. !6RECEIVE CUE SWITCH This switch has three settings, which in turn control how the Effect Received signal is monitored. When set to BLEND, users will hear both the effect receive signal and either the Cue or Master output (see 15 for more). When s

12、et to OFF, no effect receive signal will be heard. When set to SOLO, only the effect receive signal will be heard. !7POWER INDICATOR This LED will be illuminated when powered. !8EFFECT SEND ON/OFF SWITCH When on this feature will send the PGM signal (1 & or 2) to the effects send jack found on the r

13、ear panel. !9EFFECT RECEIVE LEVEL This fader when moved from DRY to WET is used to adjust the signal level received from any external effects device connected to the Effect Receive input located on the rear panel of this unit. 0PHONO/LINE SELECTOR This switch is used to determine which input source

14、is sent to the PGM. Once an input is connected to the correct PGM jack users are able to switch back and forward between either phono or line signals, effectively creating a type of transformer scratch. 1REHEARSAL MUTE SWITCH When activated this switch restricts the signal path of the PGM to only th

15、e headphone monitor, allowing you to practice a mix or scratch using the master CF but without the sound being outputted. Moreover, any adjustment to the monitor CF will have no effect to the headphone signal whilst the Freeze feature is active. Pressing both PGM 1 & 2 Freeze switches will result in

16、 all output being muted. When PGM 1 Freeze is on, the LED indicator above the button will illuminate and all signals from PGM will be routed only to the headphone section and thus not outputted. Moving the CF from position 2 to 1 will have only an effect in the headphones, facilitating practice of a

17、 mix point or scratch point. When PGM 2 Freeze is on, the LED indicator above the button will illuminate and all signals from PGM will be routed only to the headphone section and thus not outputted. Moving the CF CAUTION A function can be changed with the switch(*) under a top panel. Only the level

18、of the signal (RCV sound) inputted from the EFFECT RCV jack is adjusted at the time of Switch OFF (at the time of a initial setup), and it changes to the balance regulation volume of RCV sound and the sound of MASTER OUT at the time of Switch ON. 4 7 from position 1 to 2 will have only an effect in

19、the headphones, facilitating practice of a mix point or scratch point. 2REHEARSAL MUTE/FREEZE INDICATOR LED When the Rehearsal Mute/Freeze feature is active this LED will illuminate. 3INPUT FADER An input fader is used to adjust the input level on a given PGM. The input fader on this unit is a PCV f

20、ader and utilizes Vestax ReX fader exchange technology. This fader is user replaceable. For comprehensive information on how to replace this ReX PCV Fader please see the How To Change The Fader Unit section of this manual. 4LEVEL METER SELECT SWITCH This switch is used to select which signal level i

21、s displayed. When set to PGM, both sides of this LED section will display the current PGM level, with the left side showing PGM 1 and the right side showing PGM 2. When set to MASTER, the two LED indicators will show the L&R channels of the master signal being outputted. 5LED LEVEL METER As above. 6

22、CF REVERSE INDICATOR. This LED is illuminated when the CF has been reversed as described in !1. 7CROSS FADER (CF) Assuming that the CF reverse is off, Rehearsal Mute is off, and that the input levels of both PGM 1 and PGM 2 are properly set, then when the CF is at position 1 the signals from PGM 1 c

23、an be heard and when the CF is at position 2 the signals from PGM 2 can be heard. 8MONITER LEVEL This fader is used to adjust the volume level heard in the headphone section. 9MONITER CF This fader is used to adjust which PGM is heard in the headphone section. #0INPUT FADER CURVE SWITCHES These swit

24、ches may be used to adjust the fader curve setting for either input fader. There are three setting from which to make a selection (A, B & C) each with a different gradient. #1CROSS FADER CURVE (CF) CURVE ADJUST CONTROL This knob is used to adjust the slope of the CF curve. Any curve located between

25、the two extreme positions, gentle & steep, is possible and up to the preferred curve type of any user. Rotating this knob in a clockwise manner will produce a steep curve more suited to scratching cutting. An anticlockwise rotation will have the opposite effect of producing a gentler slope more suit
