[. . . ] No hay piezas adentro que el usario pueda reparar. Deje todo mantenimiento a los técnicos calificados. ADVERTENCIA: Para evitar corrientazos o peligro de incendio, no deje expuesto a la lluvia o humedad este aparato Antes de usar este aparato, lea más advertencias en la guía de operación. Ce symbole est utilisé pur indiquer à l'utilisateur la présence à l'intérieur de ce produit de tension non-isolée dangereuse pouvant être d'intensité suffisante pour constituer un risque de choc électrique. [. . . ] 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. A setting of less than one full clockwise turn will yield lower system noise at the expense of mixer/system headroom. AMPLIFIER INPUTS (8) The terminal strip is configured to allow balanced or unbalanced input signals. When using an unbalanced input signal, a jumper wire should be placed between the ( - ) and GND terminals. LINE OUTPUT (9) This terminal strip is provided to drive the input of other amplifiers. It is a balanced 600 ohm line output. MATRIX (10) This jack is to be used with Peavey's MediaMatrix system. This allows for remote status and control of the amplifier or several amplifiers. DC POWER CONNECTOR (11) This terminal strip should be connected to a battery backup DC power supply with a voltage of approximately 24 V DC. It is important to correctly wire this so that the positive terminal is connected to the positive side of the battery. An improper connection can result in damage to the battery and/or the amplifier. AMPLIFIER OUTPUTS (12) Fully isolated terminal strip is provided for 25 volt and 70 volt line outputs. When using the 25 volt line output the load impedance should be 4 ohm and when using the 70 volt line output an impedance of approximately 33 ohms is recommended. 4 INSTALLATION INFORMATION: POWER HANDLING AND GROUNDING For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is not advisable to remove the ground pin under any circumstances. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adapters should be used. Less noise and greatly reduced shock hazard exists when the unit is operated with the proper grounded receptacles. ARCHITECTURAL AND ENGINEERING SPECIFICATIONS The power amplifier shall have one input with provisions for balanced and unbalanced signals via terminal strip. A 600 ohm balanced line output shall be provided, also via terminal strip. [. . . ] This product should be located so that its position does not interfere with its proper ventilation. It should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air. This product should not be placed near a source of heat such as a stove, radiator, or another heat producing amplifier. [. . . ]
