Crate BT100
Crate BT100 Description:
With 100W, a 15" bass driver, and a balanced line out, this compact combo can hold its own in nearly any gig situation. It has 2 channels: a distortion channel with gain, shape, and level controls; and a clean channel with level, 4-band EQ, and an octave switch with level for boosting bottom end. Its XLR balanced line out is pre/post selectable. The CFS2 2-button footswitch is included for switching channels and kicking in the octave switch from the floor. Limiter, chromatic tuner, headphone jack, and CD inputs are also incorporated.
The Front Panel:
1. INPUT:
Use this 1/4" jack to connect your bass to the amplifier by means of a shielded instrument cable.
2. -15dB/0dB:
Use this switch to match the output signal level of your instrument to the amplifier. If your instrument
has standard pickups, setting the switch to the 0dB position (switch in the out position) should yield the best
results. If your bass has active electronics or high output pickups, set the switch to the -15dB position (switch
depressed).
3. MUTE:
This switch, when depressed, interrupts the signal prior to the power amplifier, allowing you to tune your
instrument in silence.
4. GAIN:
Use this control to adjust the amount of distortion for the Distortion channel. As you rotate the control
clockwise the amount of distortion increases.
NOTE: The BT100 employs an internal noise gate on the Distortion channel to keep residual noise to a minimum.
The Clean channel's Level control (#8) must be turned up above "0" in order for the noise gate to trigger properly.
The Gain control (#4) and input signal level also affect the noise gate.
5. SHAPE:
Use this control to adjust the tone of the Distortion channel, from a studio "V"-shaped tone to a more
"live," more present sound.
6. LEVEL:
Use this control to adjust the output level of the Distortion channel.
7. CHANNEL SWITCH:
Use this switch to select either channel. With the switch in the out position, the Clean
channel is selected. When the switch is depressed, the Distortion channel is selected. The adjacent LED illuminates
when the Distortion channel is selected.
NOTE:
When using a footswitch: when this switch is depressed,
the footswitch switches between the Distortion channel and the Clean channel; when this button is in the out position,
the Clean channel is always active, and the footswitch turns the Distortion channel on and off, allowing you
a blend of both channels.
8. LEVEL:
Use this control to adjust the output level of the Clean channel, and as part of the Octave level control
(see #13).
9. LOW:
Use this control to adjust the low frequency output of the Clean channel.
10. LOW MID:
Use this control to adjust the lower-midrange frequency output of the Clean channel.
11. HIGH MID:
Use this control to adjust the upper-midrange frequency output of the Clean channel.
12. HIGH:
Use this control to adjust the high frequency output of the Clean channel.
13. OCTAVE:
The BT100 features internal circuitry which creates a second signal which is one octave lower than
the input signal. Use this control in conjunction with the Clean channel's Level control (#8) to adjust the level of
the octave signal.
14. MASTER:
Use this control to adjust the overall output level of the amplifier.
15. LIMIT LED:
This LED illuminates when the internal limiting circuit is active. Occasional flashing during playing
is normal. If the Limit LED remains illuminated, reduce the output level of the amplifier until the LED flashes.
16. CD INPUT:
Use these RCA jacks to connect the line level (or headphones) output of a CD player, tape deck
or rhythm machine to the amplifier. The signal level from these jacks is adjusted by the Master control (#14). If the
signal from the source connected to these jacks is too strong, use the output level control on the source to adjust
the signal to obtain the proper level for a good mix.
17. HEADPHONES:
Use this jack to listen to the amplifier through a pair of stereo headphones. The internal
speaker is disconnected when the headphones jack is used. To avoid possible damage to your hearing, do
not use headphones for extended periods of time at extremely loud listening levels.
18. POWER:
Use this switch to turn the amplifier on and off. The adjacent LED illuminates when the amplifier is
turned on.
19. ELECTRONIC TUNER (top panel, not shown):
This active electronic tuner is on whenever the amplifier is
turned on, allowing you constant, "real-time" tuning. The tuner is fully chromatic – use the flat and sharp indicators
until the LED between them illuminates, indicating proper tuning.
The Rear Panel:
20. AC LINE CORD (not shown):
The grounded power cord should only be plugged into a grounded power outlet
that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements
stated on the rear panel. Do not attempt to defeat the safety ground connection.
21. EXTERNAL SPEAKER:
Use this jack to connect the amplifier to an external speaker cabinet. This jack is
wired in series with the internal speaker, which remains active when this jack is used. A 4 ohm external speaker
cabinet is recommended.
22. FOOTSWITCH:
Connect a two-button footswitch (such as the Crate CFS-2) here for remote control of the
channel selection/"blend" (see #7) and octave on/off. (When the Channel Switch [#7] is depressed, the footswitch
switches between the Clean channel and the Distortion channel; when the switch is in the out position, the Clean
channel is always active, and the footswitch turns the Distortion channel on and off, allowing you a blend of both
channels.)
23. EFFECTS LOOP SEND:
Use this jack to connect an external signal processor to the amplifier by means of a
shielded signal cable. Connect the other end of this cable to the input jack of the external processor.
24. EFFECTS LOOP RETURN:
Use this jack to connect an external signal processor to the amplifier by means
of a shielded signal cable. Connect the other end of this cable to the output jack of the external processor.
25. BALANCED LINE OUT:
Use this XLR jack to send a balanced line level signal to an external power amplifier,
mixing board, or recording console.
26. PRE/POST:
Use this switch to determine whether the Balanced Line Out signal is Post-EQ (switch depressed)
or Pre-EQ (switch in the out position).
27. GROUND LIFT:
This switch, when depressed, lifts the ground connection at the Balanced Line Out jack (#25).
This may help reduce hum in the Balanced Line Out signal.
28. VOLUME:
Use this control to adjust the signal level at the Balanced Line Out jack (#25).
