manual abstract
Check the line from the output terminal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component and rarely traced to the amplifier itself. the "Clip" LED and “Protect" LED will light simultaneously indicating amplifier fault. All channel output during the “Short Circuit Protection" will be interrupted (i.e. no sound output). Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output terminal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usually be traced to a bad cable or a bad speaker component and rarely traced to the amplifier itself. Thermal Protection -A AA single singlesingle variable-speed variable-speedvariable-speed fan fanfan on onon the thethe V1000 V1000V1000V1000plus and andand dual dualdual variable variablevariable speed speedspeed fans fansfans on onon the thethe V2000 V2000V2000V2000plus and andand V3000 V3000V3000V3000plus amplifiers provide adequate cooling. During low level output the fans run at normal speeds. During high output and as heat raises, (exceeding 90°C.), the fans will run at higher speeds to aid the cooling process. If the heatsink temperature exceeds 91°C., the amplifier will mute until the amplifier cools down. When the amplifier cools below 90°C., the amplifier will return to normal operations. Be sure not to operate your amplifier below the minimum load ratings to reduce the risk of overheating problems. Input/Output Protection -The input circuits are isolated by 10k resistors. An ultrasonic network uncouples RF from the output and helps keep the amplifier stable with reactive loads. Operating Voltage (AC Mains) -The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage is dangerous and may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier. Gain Controls -The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion during normal operation. Low Cut Filter (V2000 and V3000 Only) -The low-cut filter removes extremely low frequencies from the audio signal that could cause speaker distortion or damage. The dip switches on the rear panel allows you to enable or disable the filter for each channel, as well as adjust either a 50Hz or 30 Hz cut-off. Always use the 50 Hz filter setting if you are using the amplifier to drive a distributed line system (also known as a constant-voltage line, 70 volt line, etc.). The dip switches on the rear panel allows you to configure the low cut filter. The diagram below detail the functions of each dip switch, the functions are also printed on the rear panel of the amplifier. Configuring the Low Cut Filter: Activating Low Cut Filters -Dip switches 1 and 4 activate and deactivate the Low Cut Filter. Channel 1 filters is OFF control by dip switch 1 and channel 2 filter is controlled by dip switch 4. ON Low Cut Frequency Selector -When the Low Cut Filter is activated, dip switches 2 (channel 1) and 3 (channel 2) will control the frequency roll-off. When dip switches 2 and 3 are in the "ON" the filter will cut off frequencies CH. 1 CH.2 at and below 30Hz, when these dip switches are in the "OFF" position the filter will cut off frequencies at and 1 Low Cut 3 ON=30Hz 1 2 3 4 On/Off OFF=50Hz below 50Hz. Please note: Each channel operates independently of each other allowing each channel to have 2 ON=30Hz 4 Low Cut OFF=50Hz On/Off different filter settings.
