[. . . ] Power On/Off Switch Before applying power, check all connections and turn down the gain control. The "Soft Start" sequence starts with the POWER indicator LED at half brightness. A couple seconds later the fan starts and the amplifier cycles through one second of protective muting, indicated by the CLIP and protect LED's glowing bright red. The POWER indicator then changes to full brightness and the amplifier is ready. Peak Indicator LED Indicates that channel of the amplifier is being driven past normal power limits into distortion. Protect Indicator LED If protect conditions should occur, such as a short in a speaker cable or connector or excessively high operating temperatures, this LED will light and the amplifier will stop operation until the condition is corrected. Mono/Bridge Mode Indicator LED Shows when channels 1&2 are in the bridged mono mode. Input Level Attenuator Establishes the required input level for each channel. In the bridge mode, only the channel 1 attenuator is functional. 5 Panel Descriptions REAR PANEL 8. Note: These connectors are in parallel with the binding post connectors. Care should be taken when attempting to use both types of connector simultaneously. Failure to properly ground the unit can result in damage to the amplifier or other equipment connected to it and represents a dangerous safety hazard. Line Voltage Operate from AC mains not more than 5% above or below the specified line voltage. Pre-Connection Caution Always switch off the power and set all the level controls to minimum before making any connections. This will eliminate any chance of unexpected, loud audio transients that could damage your speaker systems. C. STEREO OPERATION Each channel provides a separate and discrete signal at the speaker outputs according to the signal received at the inputs. Set Mono/Bridge switch Set the mono/bridge switch on the rear panel to the stereo position. When the power is on, the mono/bridge LED on the front panel will not light. Input Connections With the power off, connect your input source lines to channels 1 and 2 on the PS3402. Speaker Outputs Connect speaker systems to speaker outputs as shown in figure 3. The amplifier will not operate at load conditions lower than 2 Ohms per channel. The level of the input signal should be about as high as you will ever need it to be. [. . . ] Binding Post Output Connectors These speaker connections are dual banana MDP/bare wire binding posts that will accept a standard dual banana plug or bare wire. Either method provides a safe and reliable connection capable of transferring high power signals if properly connected. To avoid ANY possible shock hazard, the power amplifier should be disconnected from the AC power source before making any connections. When connecting your speakers using either method, be sure to pay close attention to proper polarity. [. . . ]
