[. . . ] ATTENTION: Risques de choc électrique ­ NE PAS OUVRIR!ATTENTION: Afin de réduire le risque de choc électrique, ne pas enlever le couvercle. Il ne se trouve à l'intérieur aucune pièce pouvant être réparée par l'utilisateur. Confier l'entretien à un personnel qualifié. [. . . ] This means if the AC power mains are lost, the amplifier can still function. Fully isolated 25 volt and 70 volt line output capabilities are provided with this amplifier. SPSTM compression is also provided to help eliminate distortion due to clipping. A balanced 600 ohm line out is available to provide signal to additional amplifiers. FRONT PANEL FEATURES: SPSTM LED INDICATOR (1) When the SPSTM compression is active, this indicator illuminates to show that the amplifier is being overdriven to the point that the signal runs out of headroom. POWER LED INDICATORS: MAINS (2) & 24 V DC (3) Mains: Illuminates green when AC main power is supplied to the amplifier and the main power switch is turned on. 24 V DC: Illuminates red when the DC power is connected and the power switch turned on. AC POWER SWITCH (4) Depress to "on" position to turn on amplifier. DC POWER SWITCH (5) Depress to "on" position to enable DC backup power. Note: With both AC and DC power switches turned on and sufficient AC voltage being supplied, the amplifier does not draw any current from the DC supply. 3 Rear Panel: BACK PANEL FEATURES: FUSE (6) WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. CAUTION: USING A FUSE LARGER THAN THE RECOMMENDED SIZE COULD RESULT IN PERMANENT DAMAGE TO THE AMPLIFIER. The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the unit repeatedly blows fuses, it should be taken to a qualified service center for repair. INPUT SENSITIVITY CONTROLS (7) Maximum input gain (minimum sensitivity rating) is achieved at full clockwise setting. This setting yields maximum mixer/system headroom.
