User manual ALTEC LANSING 2280B POWER AMPLIFIER

[. . . ] The only way to duplicate the excitement inherent in the sound of the theatre ­ the Voice of the Theatre. Adjectives that describe the ways you feel during the film experience. The experience of sight ­ and of sound. [. . . ] Starting life purely as a cinema playback unit, it was soon in demand for use as a studio monitor and home reproducer. Many engineers still swear by the A7, and have made it their standard of comparison for everything audio. Very versatile and efficient, the A7 is ideally suited for use wherever good projection over long distances of wide-response material is required. 030519 A7 Owner's Manual 1 UNPACKING IMPORTANT: Protect the Loudspeaker The loudspeaker cone assemblies are fragile and should not be touched. Step 1 Before removing the protective shipping material, look for obvious signs of shipping damage such as severely crushed corners or deep punctures that may have marred the speaker cabinet. If severe damage has occurred, immediately contact the shipping company to file a claim. Step 2 Using a knife, carefully cut away any plastic which is holding the cardboard-encased speaker to the pallet. Step 3 Use snips to cut the straps holding the cardboardencased speaker to the pallet. Step 4 Open top of box and then slide the box up off of the speaker. The grill and horn mounting brackets are packaged separately inside the shipping box. Step 5 Remove the protective cardboard, foam, and plastic packaging material. IMPORTANT: Use Caution when Moving the Loudspeaker Because each A7 weighs approximately 200 pounds, use caution when moving the loudspeaker to avoid personal injury. Use multiple people or a dolly and protective blankets when moving the loudspeaker off of the pallet and to its final location. IMPORTANT: Retain the Packaging Material If there is a need to return the loudspeaker under warranty conditions, you will need the packaging material to properly repackage the loudspeaker for transit. 030519 A7 Owner's Manual 2 COMPONENTS The following components are contained in the A7 loudspeaker's shipping container. Cabinet ­ Model 828 This A7 Loudspeaker cabinet enclosure is hand made from 13 layer Baltic Birch and covered with a durable black splatter finish.

High Frequency Compression Driver ­ Model 902-8T Aluminum diaphragm. 8 ohm impedance. Front & Rear Mounting Brackets Used to mount the horn assembly on top of the loudspeaker cabinet. Crossover Network ­ Model N-900A 900 Hz high quality air-core inductor with low-loss polypropylene capacitors. The dial adjusts the relative loudness of the high frequency driver. Binding Posts ­ Cardas ACBP-S Two pair. Do not connect this loudspeaker to an amplifier rated at more than 200 Watts RMS per channel; significant damage to the loudspeaker could result. IMPORTANT: Wire Size High quality commercial 14 AWG, stranded, insulated wire may be used for connection of this ALTEC loudspeaker. This is considered minimum size wire for speaker/amplifier connections up to 30 feet. For wire runs longer than 30 feet, 10 AWG or larger wire is recommended. The binding posts on this ALTEC loudspeaker accommodate either banana plugs or spade connectors, although bare wire can also be used. Step 1 For bare wire without banana plugs or spade connectors, strip ½" of insulation off of both ends of the speaker wire if it has not already been done. Step 2 Connect one end of the marked wire (usually marked with a colored pattern on its insulation) to the positive (+) speaker terminal post. If using spade connectors or bare wires, tighten the nut down securely. Step 3 Connect one end of the non-marked wire to the negative (-) speaker terminal post. If using spade connectors or bare wires, tighten the nut down securely. Step 4 Lay out the wire over to the amplifier. Step 5 Connect the other end of the marked wire (refer to step 2) to the positive (+) 8 terminal on the amplifier. Step 6 Connect the second non-marked wire to the negative (-) 8 terminal on the amplifier. Step 7 Power up the amplifier and enjoy the great ALTEC sound. 030519 A7 Owner's Manual 7 SPECIFICATIONS Frequency response ±10 dB Low frequency roll-off -3 dB System power capacity Rating based on test signal of continuous pink noise, per IEC spectrum for two hours duration.
