SAFETY INSTRUCTIONS Intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacture, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14.
SERIES PROFESSIONAL POWER AMPLIFIER Thanks for choose our series amplifier. The amplifier features a two-way crossover and sub-sonic (low-cut) filter for each channel. Crossover frequencies are fixed at 150 Hz, allowing subwoofers to be driven at extremely high sound pressure levels, and the filters cut at 40 Hz to prevent low-end rumble.
FRONT PANEL FEATURES (1) INPUT GAIN (dB) These controls are used to adjust the input gain of each channel. They determine how loud each channel of the power amplifier will sound for a given input signal level. Maximum input gain is achieved at the fully clockwise setting, and this setting yields maximum mixer/system headroom.
BACK PANEL FEATURES (7) IEC MAINS CONNECTOR This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for the intended operating voltage is included in the carton. U.S. DOMESTIC AC MAINS CORD The mains cord supplied with the unit is a heavy-duty, 3-conductor type with a conventional 120 VAC plug with ground pin.

(9) SPEAKON OUTPUTS The amplifiers utilize three 4-conductor Speakon connectors, one for each channel and one for BRIDGE mode. Please refer to the BRIDGE MODE section of this manual before attempting to use this mode. For each channel Speakon, the same impedance rules apply as with the binding posts. Internally, all the Speakons are wired in what is called the “high current”...
(14) LOW CUT SWITCH This switch is used to activate the LOW CUT filter for the corresponding channel. It is again a push-push type switch, requiring a small "tool" to activate. The IN position routes the input signals through the 40 Hz LOW CUT filter, while the OUT position bypasses the filter.

levels occur Then, as temperatures in the amplifier heat sinks increase, the automatic thermal-sensing circuitry will cause high-speed operation to occur. Depending upon signal conditions and amp loading, high-speed fan operation may continue or the fan may cycle continuously between high and low. This situation is quite normal.
