Peavey CS-900 User Manual

Obviously, fora monaural biamp system (only one mixer feed], only one crossover module Is required and only one crossover island will be
used. In this case, onechannel of the CS-900 can be patcnedfortne lows and the other channel patched lorthe highs, resulting In a simple,
compact system with outstanding performance. Again, a word of caution is In order. SmcetheCS-900 is capable of producing morethan450
watts RMS per channel Into a4 ohm load, the high frequency components of the particular I oudspeakersystem must be able to handle these
power levels. Alternatives are to use a smaller power amplifier forthe entire biamp system, such as the M-7000 or M-4000, which offer the
same features as the CS*900.
The Peavey DDT compression system adds a new dimension to biamped systems. Each power amplifier channel has its own Distortion
Detection Technique circuitry, and each ie completely Independent When signal conditions exist which could cause clipping In the low
frequency power amp channel(s), the DDT system will simply llmitthat portion of thetotal biamp system. This will in no way affect the high
frequency portion of the biamp system and it is free to Increase in level until conditions exist which could cause clipping in that particular
power ampchannei(s), Althal point, the DDT system will limil the high frequency portion of the system. This is a very effective two-level
compression system and will yield sound pressure levels unmatched by conventional broad-band compression techniques.
The Peavey CS-900 offers maximum flexibility and performance features not found on most competitive units. By thoroughly
understanding the patch panel features, expansion to larger and more complex systems is only llmlied by the imagination of the user
Toward this end, we offer the following additional information which may or may not be obvious:
1, A biamp approach Is only possible with loudspeaker systems which provide access to the individual speaker comportents,
bypassing the built-in passive crossover (most Peavey loudspeaker systems offer biamp high and lowswilchingjacksontheback
panel).
2, The crossover module used must have the proper characteristics to match the particular loudspeaker system. Of greatest
imporlance is the crossover frequency. Peavey offers a variety of plug-in crossover modules which are specifically designed to
match the various loudspeakers In the product line. These crossovers have the correct crossover frequency, high trequency pad
and equalization for the particular loudspeaker, resulting in system performance with a very flat frequency response. Also
available are general purpose crossover modules at frequencies of SOO, 800, and 1200 Hz for non-Peavey loudspeaker systems.
3, The outputs of the crossover modules (both high ar>d low) can drive several power amp inputs. The parallel Input Jacks can be
used to daisy-chain to additional power amps for an expanded system on either the low or high frequency system [or both)
Remember, the components in most Peavey biampable speaker systems are 8 ohms. All Peavey CS series power ampiifjers are
rated at 4 ohms. This means that Ihe maximum number of components connected to any one particular power amplifier channel
Is TWO (two horns, two woofers). If additional components are required for additional coverage or projection, then additional
power amp channels are required.
4, The PL-2 transformer module can be removed and thejumper reinstalled inany particularcrossoverisland if a balanced input is
not desired or required for the crossover module. In this case, the associated XLR connector (9) is now unbalanced as per
previous discussion. If desired, the parallel unbalanced phone jack inputs (111 may be used to supply signal to the crossover
module m addition, whenever the XLR connector on a particular crossover island is used (either balanced or unbalanced), the
crossover input jacks (11) can be used to patch out full range signals to other ampllfler/speaker systems which are operating in
full range or other biamped systems which required different crossovers
