OPERATING MANUAL

XC3000

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 state-
variable implementation of Linkwitz-Riley crossover alignments. This provides a
24 dB/octave slope while maintaining optimal phase integrity. The XC3000 con-
tains 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 maxi-
mum signal quality and control, and should give you years of trouble free ser-
vice.

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) sep-
arate 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 ampli-
fiers 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 offer-
ing greater protection, more power with less distortion and better over-
all control of your sound system.

INSPECT YOUR XC3000 FOR ANY DAMAGE which may have occurred dur-

ing shipping.  If any damage is found, notify the shipping company and call
CARVIN immediately. 

SAVE THE CARTON & ALL PACKING MATERIALS.  In the event you have to

reship your mixer, always use the original carton and packing material. This will
provide the best possible protection for your unit during shipment.  CARVIN and
the shipping company are not liable for any damage caused by improper pack-
ing.
