26、rogrammable Bass Amplifier RadioFans.CN 收音机爱 好者资料库 4 The Front Panel: 1. INPUT 1, INPUT 2: Use these jacks to connect your instrument(s) to the amplifier by means of a shielded instrument cable. Only one Input jack is active at a time, as determined by the Input switch (#2). 2. INPUT: Use this switc

27、h to select which of the Input jacks (#1) is active. The LEDs adjacent to the jacks indicate which of the Inputs is active. This feature is perfect in situations where a player switches between two instruments during a performance: you may start with the instrument connected to Input 1, for instance

28、, then change to the instrument connected to Input 2 - without changing patch cords! 3. PAD: Use this switch to activate the input pad - if your instrument has active or high output pickups, activating the pad will allow you to set the Gain control (#4) at a more useable setting. The adjacent LED il

29、luminates when the Pad is active. 4. GAIN: Use this control to adjust the input signal level. When a sig- nal is present the LEDs around this control act as a Peak indicator: adjust the Gain control until the two LEDs furthest clockwise flash occasionally while playing. Once you have adjusted the Ga

30、in control, the LEDs serve as a VU meter and will illuminate according to the strength of the signal from your instrument. 5. ULTRA HIGH: Use this switch to boost the high frequencies. The adjacent LED illuminates when the Ultra High is active. 6. ULTRA LOW: Use this switch to boost the low frequenc

31、ies. The adjacent LED illuminates when the Ultra Low is active. 7. BASS: Use this control to adjust the low frequency output of the amplifier. 8. ULTRA MID: Use this control to adjust the midrange frequency output of the amplifier. 9. TREBLE: Use this control to adjust the high frequency output of t

32、he amplifier. 10. FX BLEND: Use this control to adjust the mix between the direct (dry) signal and the effects (wet) when the effects loop (#24-25) is used. Full counterclockwise results in all direct signal (no effect) and full clockwise gives all effect and no direct signal. The clockwise posi- ti

33、on is equivalent to a series effects loop and should be used with such devices as limiters and equalizers. 11. PRESETS: Use these switches to select one of four presets for the amplifier. Complete information on presets and programs is on page 7. 12. MASTER: Use this control to adjust the overall ou

34、tput level of the amplifier. 13. LIMIT DEFEAT: The B500DR employs a limiter circuit to prevent overdrive distortion at or near full power. This switch, when depressed, disables the internal limiter circuit. The adjacent LED illuminates when the limiter circuit is operating. 14.POWER:Use this switch

35、to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed). 123478910141213115 6 B500DR Programmable Bass Amplifier The Rear Panel: 5 15. CIRCUIT BREAKER: The B500DR employs an AC line cir- cuit breaker to help protect against damage due to excessive current dema

36、nds. If the amplifier stops working, check the circuit breaker. If it has opened, the button will be protruding and show- ing a contrasting color. You can reset the circuit breaker by push- ing it in until it latches. The breaker must cool down for a short time before the button will latch. If the c

37、ircuit breaker opens repeatedly, have the amplifier checked by a qualified service per- son. 16. AC LINE IN: Firmly insert the supplied AC power cord into this socket until it is fully seated. This grounded power cord is to be plugged into a grounded power outlet, wired to current elec- tric codes a

38、nd compatible with voltage, power, and frequency requirements stated on the rear panel. Do no attempt to defeat the safety ground connection. 17. SPEAKER OUTPUTS: The 1/4” jacks offer a convenient method of connecting to speaker cabinets using cables terminat- ed with 1/4” plugs. However, when using

39、 the amplifier at or near its full output power, using the Speakonjack is recommended. 18. FOOTSWITCH: Use this jack to connect the Ampeg AFP4BD four button footswitch to the amplifier for remote selection of the four presets. 19.BALANCED LINE OUT: Use this jack to send a pre-Master, line level sign

40、al to a house mixing board, recording console or external amplifier(s). Pin 2 = positive (+), pin 3 = negative (-). 20. LEVEL: Use this control to adjust the level of the signal at the Balanced Line Out jack (#19). 21. POWER AMP INPUT: Use this jack to connect the output of an external preamp direct

41、ly into the power amp circuitry of the B500DR by means of a shielded signal cable. The preamp sig- nal is disengaged when this jack is used. 22. PREAMP OUTPUT: Use this jack to send a preamp signal to an external power amplifier, mixing board, external effects, etc. by means of a shielded instrument

42、 cable. Using this output does not break the connection to the internal power amplifier. 23. PRE/POST: This switch, when depressed, sends a post-EQ preamp signal to the Balanced Line Out jack (#19). The signal at the balanced Line Out jack (#19) is pre-EQ when this switch is in the out position. 24.

48、nt that your B500DR should malfunction, take a few minutes to troubleshoot it before you call for service. You can save yourself time and money by doing it yourself, and often the problem is something quite simple. Presets: The B500DR has four presets which may be selected by the front panel Presets

49、 switches (#11) or by the AFP4D four button footswitch. When the B500DR is powered up, it defaults to Preset 1 - the controls will reset themselves to that Preset and the LEDs will change accordingly to indicate Preset 1s settings. The LED adjacent to the Preset 1 switch illuminates accordingly. When a footswitch is used, the LED adjacent to the footswitch pushbutton illuminates brighter than the other three LEDs - a feature performing musicians will find very useful when playing in darkened venues.
