The unit is designed to automatically cue at the first audible signal on the first of a disc when a disc is inserted. If a track is selected before a disc is inserted, the unit will automatically cue to the first audible signal for the selected track. ©American Audio® ‐ www.americanaudio.
SETTING CUE POINTS A cue point is the exact point playback will begin when the PLAY/PAUSE button (15) is pressed. A cue point may be created anywhere on a disc or in a track. Use the Jog Wheel (18) to set a cue point by frame. While the disc is in pause or cue mode, use the Jog Wheel (18) to scroll through a track to find your desired starting point. Once you have found your desired cue point press the Play button (15) to enter this point in to the unit's memory.
When you use the Jog Wheel (18), the monitor (headphone level) of a mixer allows you to hear what you are scrolling through. Once you reach your desired starting point you can set a cue (starting) point by pressing the PLAY/PAUSE button (15) as in Figure 11. Pressing the CUE Button (16) will return the disc to the cue point just set. Figure 11 FRAME SEARCH (FORWARD/REVERSE) This function lets you a frame search through a track. To do this press either the forward or reverse search buttons (13).
SETTING OUTPUT VOLUME LEVEL This function lets you set the output volume level. Press the Track knob (14) and press either the (‐) Pitch Bend button or the (+) Pitch Bend button (11) depending on if you want to raise or lower the volume. Figure 13 CHANGING THE TIME DISPLAY (26) / TIMEBAR (27) The time may be displayed in three different modes; Total Remain, Remain, and Elapsed. During normal playback, pressing the TIME button (5) as in Figure 14, will change the time display information (26) in the LCD.
TIME BAR INDICATOR The time bar in the LCD visually details the time defined in the Time Meter (26). This bar is also dependant on the selected time function; Remain (34) or Total Remain (34). This bar will begin to flash when 15 seconds of a track remain and will begin to rapidly flash when three seconds of a track remain. The flashing bar is a great visual reminder a track is about to end. The flashing bar will function regardless of which time mode the unit is in. Figure 14 ©American Audio® ‐ www.
PITCH ADJUSTMENTS This function will increase or decrease the playback speed or "PITCH" of a track. The maximum pitch bend percentage allowed is +/‐16%. The Pitch Slider (8) is used to decrease or increase the playback pitch. If the slider is moved up (towards the top of the unit) the pitch will decrease, if the slider is moved down (towards the bottom of the unit) the pitch will increase. ACTIVATING THE PITCH SLIDER (8) To activate the Pitch Slider (8), you must turn the pitch function on.
USING THE PITCH SLIDER PERCENTAGE SELECTOR (10) You may choose a pitch operating range at any time. To change the operating range be sure the pitch function is turned on, see Figure 17. The pitch percentage can be changed between +/‐4%, +/‐8%, +/‐ 16%, and 100%. 4% will allow the least amount of pitch manipulation and 100% will allow the most amount of pitch manipulation.
(+) PITCH BEND BUTTON (11) Holding down or tapping on the (+) Pitch Bend button (11) will provide a speed bump in the playback pitch. Figure 18 (‐) PITCH BEND BUTTON (11) Holding down or tapping on the (‐) Pitch Bend button (11) will provide a slow down in the playback pitch. Figure 19 ©American Audio® ‐ www.americanaudio.
JOG WHEEL (18) The Jog Wheel (18) will temporarily bend the pitch if a track is in play mode. Turning the wheel in a clockwise direction will increase your track pitch and turning the wheel in a counter‐ clockwise direction will slow your track pitch. The speed you rotate the Jog Wheel (18) will determine pitch bend percentage, to a maximum of +/‐100%. Figure 20 CREATING AND PLAYING A SEAMLESS LOOP A seamless loop is a sound loop that plays continuously without sound interruption.
Press the IN button (17). This will set the starting point of the SEAMLESS LOOP (Figure 22). The IN button (17) will blink.

ROHS – A GREAT CONTRIBUTION TO THE CONSERVATION OF ENVIRONMENT The European Union has adopted a directive on the restriction / prohibition of the use of hazardous substances. This directive, referred to as ROHS, is a frequently discussed topic in the electronic industry. It restricts, among other things, six materials: Lead (Pb), Mercury (Hg), hexavalent chromium (CR VI), cadmium (Cd), polybrimated biphenyls as flame retardant (PBB), polybrominated diphenyl, also a flame retardant (PBDE).
WEEE – WASTE OF ELECTRICAL AND ELECTRONIC EQUIPMENT Every year thousands of tonnes of electronic components, which are harmful to the environment, end up at the waste disposals around the world. To ensure the best possible disposal or recovery of electronic components, the European Union has adopted the WEEE directive. The WEEE‐system (Waste of Electrical and Electronic Equipment) can be compared with the system of the “Green Spot”, which has been in use for several years.
