The POWER/ STANDBY indicator lights up in green when the power is ON. If the amplifier has been set to STANDBY mode, the indicator is lit in orange. Lights up green when the corresponding channel's output level exceeds 2 Vrms (equivalent to 1/2 W into an 8 load, or 1 W into a 4 load). 6 Volume control knobs Each control knob adjusts the volume of the corresponding channel, in 31 steps from - dB to 0 dB. * If you wish to lock in the knob settings, you can fasten the supplied security cover over the knobs so that the settings will not be disturbed. 2 TEMP indicator Lights up red if the heat sink temperature exceeds 85°C (185°F). 3 PROTECTION indicator When the protection system is active, the PROTECT indicator light up in red and the speakers are automatically disconnected from the amplifier's outputs. The protection system activates in the following situations: When the amplifier is turned on The protection system activates for approximately three seconds when the amplifier is turned on. After three seconds, the protection system deactivates automatically and the amplifier is ready for normal operation. If a DC voltage is detected at the amplifier's outputs How to install the security cover (1) Use the supplied hex wrench to remove the four attachment screws from the amplifier. (2) Adjust the security cover to the position of screw holes. Fasten it into place using the same screws. XP7000/5000: Power shut down and the indicator is not lit. XP3500/2500/1000: The protection system is active. Once the DC voltage problem is corrected, the protection system deactivates automatically and the amplifier is ready for normal operation. If the amplifier overheats 7 Air intakes The amplifier uses forced-air cooling. The cooling fans draw air in from the front and exhaust it through the rear. Please be sure that you do not block the air intakes or exhaust vents. * The fans do not come on at initial power-on, but will switch on automatically when the temperature of the heat sink rises above 50°C (122°F). The fan speed will then vary automatically as the temperature changes. Front Rear When overheating occurs, the PROTECT/MUTE indicator lights. You should immediately turn off the amplifier and allow it time to cool down. See the Precautions section of this Owner's Manual for ways to prevent the amplifier from overheating. 4 CLIP indicator Lights up red when the output signal distortion on the corresponding channel rises above 1% -- indicating that "clipping" has occurred bacause the signal level is too high. Air intake Air exhaust 6 XP7000/XP5000/XP3500/XP2500/XP1000 Owner's Manual Rear Panel 4 3 5 6 7 1 1 XLR inputs connectors 2 7 5 MODE switch 8 These balanced XLR-3-31 type connectors are used to connect input signals. The pins are wired as shown below (IEC 60268). Hot Ground Cold * In bridged mode, only the first channel in the pair is active; i. e. , channel A of pair A/B. Make sure not to input an audio signal to an inactive input terminal. · STEREO mode In STEREO mode, channels A and B are completely independent. · PARALLEL mode In PARALLEL mode, the channel A input signal is sent both to the channel A power amp and the channel B power amp. In this case, loads are automatically connected between the A and B input terminals. · BRIDGED mode In BRIDGED mode, channels A and B operate simultaneously, functioning as a single mono amplifier. Note: When in PARALLEL and BRIDGED modes, input terminals A and B are shorted automatically. Make sure not to input an audio signal to an inactive input terminal. 2 Euroblock connectors These balanced Euroblock connectors are used to connect input signals. 6 MONITOR/REMOTE terminals This terminal is used to connect the external device for monitoring or remote control. Refer to "MONITOR/ REMOTE PIN layout" on page 15. 3 HPF switches These switches are used to turn on and off the HPF (High Pass Filter) for each channel.
