FRONT PANEL FEATURES AND
FUNCTIONS
INPUT SECTION
1. INPUT JACK; This input accepts a
standard 1/4" phone plug and is suit¬
able for any low to line level signal
source such as an electric bass*
2. - IS dB INPUT JACK; This input also
accepts a standard T/4" plug but is pad'
ded 15 dB for hotter inputs such as
tape decks or active basses*
3. GAIN CONTROL; This control sets
the amount of gain for the preamp*
EQUALIZATION SECTION
6- LOW BOOST SWITCH: Low frequen¬
cies are boosted when this switch is
depressed,
1\ GRAPHIC EQUALIZER; This is the
main tone control section of the
BT60XL Seven bands of frequencies
from 50 Hz to 5 kHz may be boosted
by moving the sliders up or cut by
moving the sliders down. The lower
frequencies are to the left and the
higher frequencies are to the right* A
great many tone variations are possi¬
ble using different settings of these
sliders.
8* HIGH BOOST SWITCH: This switch
adds additional high frequency boost
such as desired for a "popping'' or
"slapping" playing style.
9. MASTER VOLUME CONTROL: This
control sets the overall listening fevef
of the B160XL.
10. LIMIT LED INDICATOR; The B160XL
contains a power amp limiter which
automatically limits the si gnai to the
power amp to a point just below "dip¬
ping" or distortion* This is to assure a
clean undistorted sound at full power.
The limit LED indicator will be lit
whenever full power is reached*
A Jow output instrument or soft play¬
ing style requires high gain (5-10 set¬
ting) white a high output instrument
or hard playing style requires Jess gain
[1-4 setting). Too high of a setting
along with boosted equalization may
cause distortion or a harshness of
sound. If this is not desired, simply re¬
duce the gain with this control.
4, P E AK LED INDICATOR; The peak in-
dicator is Jit whenever there is distor¬
tion present in the preamp. The gain
control should be set so that the indi¬
cator flashes occasionally or does not
EFFECTS LOOP
11 - EFFECTS LOOP OUTPUT; This jack
may be connected to the Jine level
input of an external effects device.
This jack may also be used as a "direct”
unbalanced send for recording, etc.
12- EFFECTS LOOP INPUT: This jack
may be connected to the line level
output of an external effects device.
This "Post Gain'' configuration is help¬
ful in obtaining optimum input signal
levels to external devices and reduc¬
ing the noise levels associated with
them*
CHORUS SECTION
13- CHORUS SWITCH: The chorus effect
is turned on when this switch is de¬
pressed.
14. SPECTRUM CONTROL; With this
control fully counterclockwise the full
frequency spectrum of the signal is
chorused* As the control is turned
clockwise low frequencies are al¬
lowed to pass with no chorus effect
allowing a more "tight" or punchy
low end sound with upper harmonic
chorusing. This is usually desirable
when playing in a "live" situation*
15. DEPTH CONTROL: This control is
used to set the "depth" or amount of
tight at all during normal playing,
5. P RE-SHAPE CONTROL; This is a pre-
EG "master” tone control. With the
control set at "12 o'clock", the signal
will pass to the EQ section "flat” (with
no modification of tone). As the con¬
trol is turned clockwise, high frequen¬
cies will be boosted and as the control
is turned counterclockwise* low fre^
quendes will be boosted* This control
can be used to "dial in" a general tone
setting which can be fine tuned by
the EQ section or to instantly modify
an existing EQ setting with one knob.
chorus effect.
16- RATE CONTROL: This control Is used
to set the rate of chorusing. This con¬
trol when used in conjunction with
the Depth control allows a wide
range of chorus effects from a subtle
chorus effect to far out sound effects.
17. LINE OUT LEVEL CONTROL: This
control Is used to set the level of the
balanced line output jack.
18. BALANCED LINE OUTPUT JACK;
This jack provides a balanced output
signal for connection to an external
power amp, tape deck, or mixing
board.
19. ON/OFF LED INDICATOR; The LED
will be lit when the amplifier is turned
on,
20- POWER SWITCH; Pushing the switch
to the up position turns the BT60XL
on.
