A lntended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
A WARNING! For optimum performance and reliability DO NOT PRESENT THE AMPLIFIER WITH A SPEAKER LOAD OF LESS THAN 2 OHMS, OR A COMBINATION OF SPEAKERS THAT TOGETHER ARE LESS THAN 2 OHMS! Using one speaker, it must be rated at 2 ohms minimum. Using two speakers, they must be rated each at 4 ohms minimum.

that particular channel. Operation at power output levels below 100% will naturally be indicated by lower LED readings. The lowest value indicated is 0.4% of full power, which corresponds to 2.0 watts RMS output into 4 ohms. Operation below that power level will not be indicated, since the lowest LED is calibrated at 0% or standby.
A GRILLE (6) The back panel includes the fan opening with protective grille (6), where cooling air is drawn into the amplifier. This opening should never be blocked or restricted. DDT SWITCH (7) This switch is used to either ENABLE or DEFEAT the DDT compressor.
MODE SWITCH (10) The mode switch is located on the “back-porch” next to the channel input jacks. This switch converts the CS 1200X from normal stereo mode to bridge mode. Bridge-mode operation is very popular for commercial sound distribution systems (70/l 00 volt lines).

per channel or 4 ohms BRIDGE mode for any application. Operation at loads of 4 ohms per channel or 8 ohms BRIDGE mode is more desirable for sustained operation applications, be- cause the amplifier will run much cooler at this load.
OPERATION The CS 1200X is designed for maximum ease and flexibility of operation. When the unit is installed and connected as described in the previous sections, operation is as simple as turning on t.
2. STEREO MODE (BALANCED INPUTS) When conditions require the use of a balanced input at the power amplifier, the XLR connectors (11) on either or both channels can be converted to a balanced configuration by removing the jumper plug from the transformer accessory socket (12) and plugging in an input transformer module (PL-2).

turn really is maximum compression range), the input sensitivity control should be set at Ihe maximum clockwise setting. This is always the best setting to start with.
normal intermittent applications, low-speed fan operation will provide adequate cooling. Since the CS 1200X is a redundant two-channel amplifier, but only one fan is employed, the fan circuitry is an independent system, separately fused internally. You will notice that the heat sink components are divided horizontally.
The result usually is severe clipping (distortion) of the high-frequency material. In a biamplified system, the high-frequency material is routed to its own power amplifier (and associated loud- speaker), which avoids the clipping problem.
