Crate CA120DG
Crate CA120DG Description:
New for 2004, we are introducing an entirely new range of acoustic amplifiers. The technology in the New Crate Acoustic Series is unique, with preamp circuits you can tailor for piezo or active systems or BOTH!!. Our NEW feedback elimination circuits are efficient and simple to use and on the 60 and 120 watt units include the ability to automatically eliminate feedback at two different frequencies. Every CA amp has a high frequency component for crisp, clear highs. On the CA120DG model we include special features for live performance like XLR & 1/4" balanced line out with Level control which does not affect your stage volume. They also have ground lift on the Line Out, Tweeter Level control, Effects Loop and a two button footswitch for Internal Reverb/Effects and Chorus switching. Also included are a wide array of Reverbs, Delays, Chorus and Multiple Effects settings.
Crate CA120DG The Front Panel:
1: Low-Z.
The signal from a low impedance microphone may be connected
here by means of a shielded, balanced microphone cable terminated
with an XLR connector. This jack has 15 volts phantom
power applied to pins 2 and 3. (Mics not requiring phantom power
will not be affected.)
2: Gain 1.
This serves as the input level control for the XLR Input jack
(#1). For the best signal to noise ratio set this control so the Peak LED
(#5) flashes on strong signals.
3: High-Z.
The signal from your acoustic instrument may be connected
here by means of a shielded signal cable. This input will accommodate
a piezo pickup or an active system.
4: Gain 2.
This serves as the input level control for the High-Z jack (#3).
For the best signal to noise ratio set this control so the Peak LED (#5)
flashes on strong signals.
5: Peak.
This LED flashes when the signal level into the preamp
approaches clipping. Adjust the Gain controls (#2, #4) until a strong
signal causes this LED to flash.
6: Low.
This serves as the bass control. Adjust this control to get the best
sounding bass response for this channel. Excessive boost of the low
control can cause an unnatural howling and should be avoided.
7: Mid.
This serves as the midrange control. Adjust this control to get
the best projection and midrange tones for your instrument. The center
point of the mid control is chosen by the setting of the Contour
control (#8).
8: Contour.
Use this control to set the center point of the Mid control
(#7). Set this control at the frequency which gives you the most natural-
sounding midrange tones.
9: High.
This serves as the treble control. Adjust this control so your
high notes and harmonic overtones are lively but not overpowering.
10: DSP/Eff Send.
Use this control to adjust the amount of internal
Digital Effect and/or external effect (if used).
The Master Section - part one:
11: CD Input.
Use these RCA jacks to connect a CD or tape player to the
amplifier. Use the CD Level control (#12) to adjust the level of the
player.
12: CD Level.
Use this control to adjust the signal level at the CD Input
jacks (#11).
13: Tweeter Cut.
Use this control to reduce the output level of the internal
high frequency driver. In the fully counter-clockwise position, the
tweeter is at its full output level. As you rotate the control clockwise,
the tweeter level decreases. Adjust this control to best suit your playing
environment.
14: Feedback Filters.
Use these switches to activate the CA120D's
advanced feedback elimination circuitry. For complete details, see the
section entitled To Eliminate Feedback" on page 6.
The Effects Section:
15: Mode.
Use this control to select the type of Digital Signal Processing
effect applied to the output signal. For a listing of the effects, please
see the section entitled "The DSP Section" on page 6.
16: DSP Level.
Use this control to adjust the amount of internal DSP
effect.
17: Aux In/Eff Ret.
Use this control to adjust the mix of the line level signal
applied to the Effects Aux In/Eff Ret jack (#24, page 5) with the main
input signal.
The Master Section - part two:
18: Level.
Use this control to set the overall output level of the amplifier.
Crate CA120DG The Rear Panel:
19: Power.
Use this switch to turn the amplifier on (top of the switch
depressed) and off (bottom of the switch depressed.) The power
switch illuminates when the amplifier is on.
20: AC Line Cord.
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 speakers
which remain active when an external speaker is connected.
22: Feedback Filters Footswitch.
Connect the three-button footswitch to
this jack for remote control of the feedback filters. The Feedback
Filters ON LED (#14, front panel) illuminates and the feedback circuit
is activated when a footswitch is connected to this jack. Footswitch
button #1 controls Feedback Filter 1, button #2 controls Filter #2. (See
illustration below.)
Note:
This is a STEREO jack: tip = Filter 1, ring = Filter 2, sleeve is
ground. Use only a footswitch equipped with a stereo 1/4" plug.
23: DSP A/B Bank Footswitch.
Connect the three-button footswitch to
this jack for remote control of two DSP settings:
1.With footswitch button #3's LED illuminated, select one of the DSP
settings
2.Step on footswitch button #3 - the LED will go out - select a different
DSP setting
3.Step on footswitch button #3 again - the LED illuminates, and the
DSP automatically changes back to the setting chosen in step 1.
4.Step on footswitch button #3 again - the LED goes out, and the DSP
automatically changes back to the setting chosen in step 2.
24: Effects Aux In/Eff Ret.
When using an external signal processor or any
line level signal (drum machine, keyboard, etc), connect the output of the
device to this jack by means of a shielded signal cable.
25: Effects Send.
When using an external signal processor, connect this
jack to the input of the effect by means of a shielded signal cable.
26: Line Out Level.
Use this control to adjust the output level of the line
out signal. (This control works independently from the amplifier's
master level control.)
27: High Z Bal Line Out.
Use this jack to connect a high impedance, line
level signal to a house sound board, a recording console or an external
power amplifier by means of an 1/4" stereo plug-terminated
cable. (Ring is signal +, tip is signal -, and sleeve is ground.)
28: Gnd Lift.
This switch, when depressed, electronically disconnects
both of the Line Out jacks' (#27, #29) chassis ground connections. If
you experience excessive noise when using the Line Out jacks,
depress this switch.
29: Low Z Bal Line Out.
Use this jack to connect a low impedance, line
level signal to a house sound board, a recording console or an external
power amplifier by means of an XLR-terminated cable. (Pin 1 is
ground, pin 2 is signal +, and pin 3 is signal -.)
The DSP Section:
The CA120D features Crate's On-Board Digital Signal Processing
(DSP) technology that was designed specifically for use with
acoustic instruments and vocals. This provides a large selection
of digital reverbs, effects and delays. Select the type of effect
desired by rotating the Mode control (#15). The effects are
described below.
When a footswitch is used in the DSP A/B Back Footswitch jack (#23), a
separate DSP setting can be stored and recalled for each of the
footswitch's two button positions (LED on, LED off). Refer to the steps on
