Attenuation allows the Gain control (#4) to be used in a more usable (higher) position. If clipping is indicated with the Gain control at a low setting, attenuation is needed. 3. PEAK LED: This LED flashes when the signal level into the preamp approaches clipping. Adjust the Gain control (#4) until a strong signal from your instrument causes this LED to flicker. NOTE: If the LED flashes frequently with the Gain at a low setting, use the -15dB pad (#2) to attenuate the input signal and readjust the Gain. 4. GAIN: This serves as the input level control for the amplifier. For the best signal to noise ratio set this control so the Peak LED (#3) flashes when you strike a string fairly hard. 5. DRIVE: This control is used to overdrive the preamp in order to get various harmonic enhancement or distorted sounds. In the fully counterclockwise position the preamp is in the cleanest condition. As the control is rotated clockwise, signal level is increased to drive the preamp harder (into distortion). The tone of the signal is also changed to provide a smoother overdrive. (The tone controls may have to be readjusted to obtain the overall desired tone.) The Gain control (#4) and - 15dB Pad (#2) interact with the Drive control. For greater overdrive, the Pad switch should be out and the Drive control fully clockwise. Use the Gain control to set the amount of overdrive desired. The Peak LED (#3) will illuminate steadily when the amp is used in this manner. 6. BASS: This is the primary low frequency control which allows for 12dB of cut or boost at 50Hz. 7. ULTRA MID: This is the primary midrange control. Rotate this control to the left of center for a “contoured” sound (more distant, less midrange output) or to the right of center for a pronounced (more up-front) tone. 8. TREBLE: This is the primary high frequency control which allows for 22dB of cut or 17dB of boost at 5kHz. 9. EQ ON LED: This LED illuminates when the EQ is turned on by either the Master Control (#11) or a footswitch (#24, rear panel). 10. GRAPHIC EQ: These sliders control the output frequencies indicated above each control. The center position of each control is flat (no boost or cut). 11. MASTER: Set the overall output level of the amplifier with this control. Pulling this knob out actives the Graphic EQ (#10). When a footswitch is connected (#24, rear panel) this switch is disabled. 12. BALANCE (B3158 only): This control proportions the output signal between the low and high frequency output jacks (see #18, rear panel) when using the amp in the biamp mode. 13. LIMIT LED(S): The LED illuminates whenever the amplifier is near full output, indicating that the internal limiter is keeping the output from distorting. NOTE: There are two Limit LEDs only on the B3158: one for its low frequency power amp and one for its high frequency power amp. 14. POWER ON LED: This LED indicator illuminates when the POWER switch (#15) is ON. 15. POWER SWITCH: This heavy-duty rocker switch applies the power to the amplifier. The amp is ON when the top of the switch is depressed, OFF when the bottom of the switch is depressed. 1. ENTRADA: Conecte aqui su guitarra de bajos usando un cable blindado para instrumentos. 2. TERMINAL DE -15dB: Si su bajo tiene captadores ...
