Hughes & Kettner 250BASS Musical Instrument Amplifier User Manual


 
(8) TREBLE:
The TREBLE pot adjusts the high frequency through a wide band and determines
the amount of bite and harmonics. The center frequency is app. 8khz.
(9) FX-MIX:
The Bassbase 250 is equipped
with
an effects loop switched in parallel for
external effects devices. Conventional effects loops, switched in series, send the
entire signal through the effects device, whereas the Bassbase’s FX-MIX pot
allows you to determine the precise amount of the original signal you want to
send through an effects device.
FX-MIX: The far left position allows none of the signal to be sent down the
effects loop path. Rotate the pot to the far right, and the entire signal is sent for
processing. (The effects path functions now in the same fashion as in a
conventional effects loop).
NOTE: If you choose not to connect an external effects device, ensure the
FX-MIX pot is rotated completely left!
The effects loop can be switched on and off via a footswitch.
(10) MASTER VOLUME:
controls the overall volume of the BASSBASE 250.
(11) DYNACUP:
A control LED illuminates when DYNACLIP is operational.
DYNACLIP is a power amp circuit that was developed exclusively for the
BASSBASE. It efficiently suppresses power amp clipping without sacrificing
peak dynamics, as opposed to peak limiters. Unpleasant and potentially speaker
damaging distortion is avoided and the effective power output is increased.
(12) BAL.PA OUT:
This XLR output jack sends a transformer balanced signal to feed a PA board.
(13) DIRECT:
Depress the DIRECT switch to bypass Gain, tone controls and the effects
loop to send an instrument signal via BAL.PA OUT.
