If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment on and off, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the antenna. • Increase the sepa...

3. Clip/limit indicator This indicator signals when the amplifier output is clipping or limiting. It has two different indication states: If the clip limiter is engaged, it has a short time constant and it illuminates briefly. (See page 13 ). If the clip limiter is not engaged, it has an increased t...

8. Gain switch channel A . Three of the switches in the DIP-switch selects the maximum gain of the channel to be either 20, 23, 26, 29, 32, 36, 39 or 41 dB. (See page 6 ). 9. AC power cable. WARNING! A label just below the mains cable on the rear of the amplifier indicates the AC mains voltage, for ...

5.2 Link switch The Link switch located on the rear panel (the central DIP-switch) is for changing the operation mode of the amplifier (see below, section 5.3). 5.3 Operation modes 5.3.1 Stereo mode In this mode, both channels operate independently of each other. This is used for all 2-channel modes...

5.3.5 Bridge mono mode features Bridged mono mode combines the power of both channels into one speaker. This results in twice the voltage swing, four times the peak power and just less than three times the full power of a single channel. One way to understand the load and power from the amplifier’s ...

6.3 Operating voltage WARNING! ! A label just below the mains cable on the rear of the amplifier indicates the AC mains voltage, for which the amplifier is wired. Connect the power cable only to the AC source referred to on the label. The warranty will not cover damage caused by connecting to the wr...

clip and is therefore the highest power level one can obtain without completely obliterating the program. Last , the "normal operating power", as defined by the safety standard IEC 65/ANSI/UL 6500 and used by a majority of safety agencies. The normal operating power is measured using pink no...

Within the Neutrik® Combojack there is a ¼”(6.3mm) phone jack, which is wired in parallel with the XLR. TIP HOT RING COLD SLEEVE SHIELD/GROUND Figure 6. ¼” TRS plug The input impedance is high enough (20 kohms balanced) to allow ”daisy-chaining”, or multiple parallel input connections. The headroom ...

7.2 Connecting speakers Speaker connections are made via the two Neutrik® NL4FC Speakon connectors. The Speakon onnector is designed for high power speaker connections. It assures the correct polarity, it locks in nnel A and B outputs, so it’s useful for bridging and bi-amp age 7 cplace and prevents...

8.2 Powering up – Soft start When you power up the amplifier it takes a couple of seconds to check its circuits. This is known as the "soft-start" or "slow-start" sequence. The fans then blow at high speed before going into "idle" and the two bottom green LED’s illuminate to ...

9.1.2 Thermal protection If the amplifier is driven very hard into a low impedance load, the cooling fans will run at high speed. If the causing conditions continue, the Temperature indicator(s) will illuminate indicating that the amplifier is about to go into thermal shutdown. After five seconds th...

mistake to a 3 phase supply, an internal non-resetable fuse or resistor may have blown. Then return the amplifier to your supplier for service. Fault: The amplifier does not respond even after checking above items. In the unlikely event of on a non-user rectifiable fault, return the amplifier to you...
