Anleitung Zusammenfassung
0 dB INPUT: The signal output from a passive instrument may be connected to this 1/4" input by means of a shielded instrument cable. 2. –15 dB INPUT: The signal output from an active instrument may be connected to this 1/4" input by means of a shielded instrument cable. 3. VOLUME: Use this to control the overall output level. It affects the preamp level to speaker and phone outputs. Use it wisely, and turn it down when making connections, putting on headphones, or trying something new. It does not affect the signal fed to the CD input. 4. TREBLE: Use this to adjust the high frequency level of the amplifier. This provides up to 14 dB of boost, or –14 dB of cut at 5 kHz. The high frequency output is flat at the center position. 5. MID: Use this to adjust the midrange frequency level of the amplifier. This provides up to 12 dB of boost, or –12 dB of cut at 600 Hz. The midrange frequency output is flat at the center position. Rotate the control counter clockwise for a “contoured” sound (more distant, less midrange output) or clockwise for a sound which really cuts through. 6. BASS: Use this to adjust the low frequency level of the amplifier. This provides up to 12 dB of boost, or –12 dB of cut at 40 Hz. The low frequency output is flat at the center position. 7. CD LEVEL: Use this to control the output level of the signal fed to the CD input. Use it wisely, and turn it down when making connections, putting on headphones, or trying something new. 8. CD INPUT: The audio output from linelevel sources, such as an iPod®, MP3, or CD player, can connect to these RCA inputs. The incoming audio is mixed with the preamp signals, so you can play along to a practice track, as you listen with headphones. 9. PHONES: Use this 1/4" TRS stereo output to connect your headphones. The output here is a mix of the line-level signals reaching the amplifier, and any incoming audio from the CD input jacks. Before putting on headphones, make sure the volume control is turned down, and (if connected) any external audio source has its level turned down. This will reduce the chance of hearing damage due to loud volumes. Note: the speaker is muted when headphones are plugged in. 1 2 3 4 5 6 7 8 9 10 11 ....

ON LED: This LED illuminates red when the power is on. 12. EFFECTS RETURN JACK: Use this 1/4" TS unbalanced input to return the processed line-level output of an external effects processor (for example). The processor could be fed by signals from the effects send. 13. EFFECTS SEND JACK: Use this 1/4" TS unbalanced output to send a line-level output to an external effects processor (for example). The output here is affected by all controls except the volume. Use the effects return jack to feed the returned processed signals back into the power amplifier. 11. POWER SWITCH: Use this switch to turn the overall system power on or off. Press the top of the switch to turn on the power, and press the bottom to turn it off. 12 13 14 ........................ Return Send Line out 14. 1/4" LINE OUT JACK: Typically, you would connect this post-EQ, unbalanced output to the unbalanced input of an external mixer, or a recorder. In this way, you do not have to mic the speaker cabinet in order to add it to the main mix, or to record. The level of this signal is affected by the volume control. This output can connect to external power amplifiers, or powered loudspeakers, as long as they have their own input controls to adjust the volume level.
