Congratulations on your purchase of the CARVIN XC3000 Stereo 2 / 3 - way
Electronic Crossover. The XC3000 was designed with the professional in mind.
Your unit has been engineered and assembled in the U.S.A., using only high
quality electronic components and uncompromising workmanship. The XC3000
provides the best available crossover networks consisting of a forth-order statevariable implementation of Linkwitz-Riley crossover alignments. This provides a
24 dB/octave slope while maintaining optimal phase integrity. The XC3000 contains a host of valuable features found in only the best of professional audio
equipment. These include a switchable 40Hz Sub Sonic filter, a 10x frequency
multiplier, switchable Tri-Amp and Bi-Amp modes, balanced input and output
connectors, and phase inversion switches. The XC3000 is designed for maximum signal quality and control, and should give you years of trouble free service.
BI-AMP & TRI-AMP THEORY
Bi-Amplification and Tri-Amplification involve higher protection to
sound systems as well as increased performance. Bi-Amping involves
dividing a full range signals into two distinct low pass and high pass
(low frequency and high frequency) signals and then amplifying these
signals with separate amplifiers for later connection to their proper
woofer and horn speakers.
Tri-Amplification involves the same principle as Bi-Amping except that
separate high-pass, mid band, and low pass signals are fed to (3) separate amplifiers for subsequent connection to woofer, midrange, and
high frequency speakers.
These frequency divisions are done actively with an efficient
24dB/octave roll off prior to the power amplifiers. This allows the amplifiers to power a defined frequency range (low, mid or high) instead of a
full range frequency signal. Due to increased efficiency of the amplifier
(amplifying a distinct frequency range), a cleaner, and more powerful
output is afforded. Bi/Tri-Amplifying is especially useful in selecting any
number of various crossover points and adjusting individual frequency
level gain., thus enabling you to better control the overall response of
your sound system. Bi/Tri-Amplification is useful as a means of offering greater protection, more power with less distortion and better overall control of your sound system.

1. PEAK INDICATOR
The peak indication LED light is used to monitor both input and output distortion. THis indicator will flash whenever any of these
two conditions or a combination of these condition exist. Should the peak indicator ever flash, you can compensate this condition by
adjusting the gain control down (lower) accordingly.
2. GAIN
This control establishes the amount of input gain for the crossover. This control will also affect the output drive of the crossover
thereby adjusting the overall gain of the crossover as well. Note: This control is best used in conjunction with the “peak” level
indicator as a means of monitoring the amount of input gain and output distortion as it relates to any overload conditions.
3. SUB SONIC FILTER
This button provides a third-order high pass filter set at 40Hz. This allows you to reduce sub sonic noise, allowing your power
amps and speakers to operate safely and more efficiently.
4. LOW LEVEL
The LOW LEVEL control sets the output level for the channels LOW OUT jack. Which frequencies will be cut or boosted at this control is dictated by the position of the LOW/MID frequency selector. For example, if the LOW/MID frequency control is set at
300Hz, the frequencies at and below 300Hz will be volumetrically boosted or cut by adjustment of the LOW LEVEL control.
5. MID LEVEL
The MID LEVEL control sets the output level for the channels MID OUT jack. Which frequencies will be cut or boosted at this control is determined by the positions of the LOW/MID and MID/HIGH frequency selectors.
6. HIGH LEVEL
The HIGH LEVEL control sets the output level for the channels HIGH OUT jack. Which frequencies will be cut or boosted at this control is determined by the position of the MID/HIGH frequency selector.
7. LOW / MID FREQUENCY SELECTOR
This control sets the desired upper frequency crossover point for the LOW OUT and lower frequency crossover point for the MID
OUT. The frequency indicated by the knob pointer of this control establishes the LOW/MID crossover point for the channel.
8. 1X / 10X BUTTON
This button multiplies the selected frequency for the LOW / MID crossover network, by 1X or 10X as needed to establish a full
range frequency spectrum from 50Hz to 10kHz. With the 1X button in the “out” position the crossover will sweep from 50Hz to
1kHz. With the 10X button pushed “in” the crossover has a range from 500Hz to 10kHz.
9. MID / HIGH FREQUENCY SELECTOR
This control sets the desired upper frequency crossover point for the MID OUT and lower frequency crossover point for the HIGH
OUT. The frequency indicated by the knob pointer of this control establishes the MID / HIGH crossover point for the channel.
10. 2 WAY / 3 WAY BUTTON
This switch sets the XC3000 into either Bi-Amp or Tri-Amp mode. In the out position the unit is set for Tri-Amp mode. When the
button is depressed the unit will operate in Bi-Amp mode, and the MID LEVEL control and output jack is not used.
11. POWER INDICATOR
This LED illuminates when power is applied to the unit.
12. POWER SWITCH
Push this switch vertically to the “on” position to apply power to the unit. The power indicator LED will light to show that the
XC3000 is on.
CHANNEL TWO
The controls of Channel “TWO” are identical to the controls of Channel “ONE”.

1. LINE CORD
All Carvin equipment is supplied with 3 conductor line cords for maximum safety, greatly reducing the chance of electrical shock.
If the XC3000 unit is to be plugged into a (2) prong outlet, use a quality 3 to 2 prong grounded adapter. Do not defeat the grounding
pin of your AC line cord as this is for your protection.
2. GROUND LIFT SWITCH
Useful in getting rid of ground loop buzzing. This switch lifts the grounds on the nputs and outputs.
3. BALANCED XLR INPUT
Offers the best connection to the XC3000. The XLR connector wiring is as follows: Pin #1 ground, Pin #2 Positive Balance, Pin #3
Negative Balance.
4. BALANCED 1 / 4” PHONE INPUT
The balanced 1 / 4” phone input jack will accept either balanced or non-balanced connections. For best results use balanced (Tip,
Ring, Sleeve) connections to reduce cable hum.
5. PHASE INVERTER SWITCH
The PHASE inverter switch gives you the option of inverting the phase
of each of the main output to correct any phase inversion problem at your speakers or power amps.
6. LOW OUT XLR
The LOW OUT 1 / 4” phone jack provides a balanced output for the low pass filter of the channel. This is where you connect the
power amp that will be driving your bass cabinets.
7. MID OUT XLR
The MID OUT 1 / 4” phone jack provides a balanced output for the band pass filter of the channel. This is where you connect the
power amp that will be driving your mid range cabinets.
8. HIGH OUT XLR
The HIGH OUT 1 / 4” phone jack provides a balanced output for the high pass filter of the channel. This is where you connect the
power amp that will be driving your high frequency horns or tweeters.
9. MONO (LOW 1+2) SWITCH
Combines both signals from each channel’s low pass filters. Either or both LOW outputs may be used. This is where you would
connect a power amp to drive a mono subwoofer sustem.
