18、direction (see front panel item 38). 34 MASTER LEVEL display button and indicator When depressed to the On position, the indicator lights and the level meters display the master output (stereo) peak levels. When turned Off, the level meters display the peak levels for CH-1 (left) and CH-2 (right) (s

19、ee also item 27). 35 CH-2 fader lever The CH-2 fader lever is used to control the level of signals sent to the cross fader. Signal level is maximum at scale mark “10,” and minimum at scale mark “0”. When the front panel CH-2 FADER REVERSE switch is set to ON, the signal level is maximum at scale mar

20、k “0,” and minimum at scale mark “10”. The channel fader curve can be adjusted by means of the front panel FADER CURVE dials. 36 CH-2 FADER START indicator Lights when the CH-2 fader start/back cue function is enabled (see also top panel item 31 and front panel item 39). 37 C.F.2 FADER START indicat

21、or Lights when CH-2 cross-fader start/back cue function is enabled (see also top panel item 31 and front panel item 39). DJM-707128 1234 1234 C D F A B E Front Panel 38 FADER REVERSE switches CH-1 ON/OFF When set to ON, the top panels CH-1 REVERSE indicator lights, and the CH-1 fader lever operates

22、in the reverse direction (scale mark “0” becomes 0 dB attenuation, and “10” becomes minus infinity). The fader start function also operates in reverse. CH-2 ON/OFF When set to ON, the top panels CH-2 REVERSE indicator lights, and the CH-2 fader lever operates in the reverse direction (scale mark “0”

23、 becomes 0 dB attenuation, and “10” becomes minus infinity). The fader start function also operates in reverse. C.F. ON/OFF When set to ON, the top panels cross fader REVERSE indicator lights, and the cross fader lever operates in the reverse direction (left side becomes CH-2, and right side becomes

24、 CH-1). The fader start function also operates in reverse. 39 FADER START selector switches C.F.1 / CH-1 This switch determines whether the fader start operation for the CD player connected to CH-1 is activated by the cross fader lever, or by the CH-1 fader lever. When the top panels CH-1 FADER STAR

25、T button is set to On, selecting C.F.1 causes the top panels C.F.1 FADER START indicator to light, and selecting CH-1 causes the top panels CH-1 FADER START indicator to light. C.F.2 / CH-2 This switch determines whether the fader start operation for the CD player connected to CH-2 is activated by t

26、he cross fader lever, or by the CH-2 fader lever. When the top panels CH-2 FADER START button is set to On, selecting C.F.2 causes the top panels C.F.2 FADER START indicator to light, and selecting CH-2 causes the top panels CH-2 FADER START indicator to light. 40 Headphone output jack (PHONES) Acce
