Peavey CS 1200 User Manual

MAINS POWER SWITCH (5)
The tront panel of the CS-1200 contains a conventional type on/off rocker switch. When the amplifier is plugged into a suitable power
source, activating this switch should light both channel "O’ array LED's afterthe power-updelay sequence is completed (approximately two
seconds). You should also be ableto hear the output relays close (click). If the amplifier is cool, the fan should start on low speed operation. If
only one channel "0” indicator lights, then the possibility exists that the mains fuse on the other channel has blown. If neither channel "0"
indicator lights, then check the main power source. It’s always a good idea to check to see that the fan is operational, especially on a new unit.
The possibility existsthat due to shipping and handling, thcfan bearings might be too tight to allow low speed fanoperation. If This isthecase,
immediately seek professional help. The CS-1200 must have normal fan operation to provide adequate cooling for the unit. Without airflow,
the amplifier will '‘thermal” very quickly under any signal conditions.
BACK PANEL (6)
The back panel of the CS-1200 contains a “back porch” design which contains the various input and output connectors for each channel.
Also included is the patch panel to provide the user with a very flexible system to facilitate the use of balanced input transformers and dual
crossover networks. These features are unduplicated in any other stereo power amp on the market today The back panel also includes the
fan opening with protective grille (6) where cooling air is drawn into the amplifier. This opening should never be blocked or restricted.

FUSES (8)
Each channel of the CS-1200 is fused with a standard 10 amp. 125 VAC fuse. Always replace with the same type and rating. Failure to do this
could void the warranty on the CS-1200.
MODE SWITCH (16)
The mode switch is located on the “back porch” next to the channel input jacks. This switch converts the CS-1200 from normal stereo mode
to bridge mode. Unless theamplifier isto be used in a commercial sound distribution system (70/100volt lines), the bridge modeshould not
be used. In certain crossover applications, accidental switching to the bridge mode could destroy the speaker system. Applications of the
bridge mode will be covered later in this manual.
PATCH PANEL
The patch panel of the CS-1200 offers many features that make the amplifier more flexible. In order to simplify the explanation, four basic
modes of operation will be introduced. Simplified functional diagrams are printed on the top of the CS-1200 showing these four modes. These
diagrams also appear in this manual for discussion purposes.
