User manual AUSTRALIAN MONITOR AMPCS60

[. . . ] Precautions should be taken so that the means of grounding of a piece of equipment is not defeated. Mains voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connection to improper AC voltage is not covered by any warranty. Have gain controls on amplifiers turned down during power-up to prevent speaker damage if there are high signal levels at the inputs. [. . . ] Do not ground any red ("hot") terminal. Never connect a "hot" (red) output to ground or to another "hot" (red) output!The power cord of equipment should be unplugged from the outlet when left unused for a long period of time. Service Information Equipment should be serviced by qualified service personnel when: A. The power supply cord or the plug has been damaged. Objects have fallen, or liquid has been spilled into the equipment The equipment has been exposed to rain The equipment does not appear to operate normally, or exhibits a marked change in performance The equipment has been dropped, or the enclosure damaged. Thank you for choosing the Australian Monitor AMPCS60 premium ceiling speaker. The AMPCS60 has been developed using innovative design and materials to meet the demanding constraints of high quality foreground/background sound reproduction from a ceiling-mounted speaker. Featuring a sealed metal back box, the 6. 5" woofer gives superior bass response to a conventional ceiling speaker. The 3/4" titanium tweeter is horn-loaded to maximize high-frequency coverage. Rated at 60 watts, with 70/100V tappings at 7. 5, 15, 30 and 60 watts, the AMPCS60 also features a 16 ohm transformer bypass setting. Included mounting hardware give ease of installation combined with safety. FEATURES INSTALLATION SPECIFICATIONS 2 3 8 THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL AUS, EUR, USA Copyright 7 Nov 2005 Rev A: 7 Nov 2005 This symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. This symbol is intended to alert the user to the presence of important operation and maintenance (servicing) instructions in the literature accompanying the appliance. Caution: To prevent electric shock do not use this (polarised) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. To prevent electric shock, match wide blade of plug to wide slot, fully insert. FEATURES INSTALLATION Diagram 1 The AMPCS60 and supplied mounting hardware has been designed for easy installation while maintaining a high standard of safety. The whole installation process can be completed from below the ceiling, if necessary, although working from both sides of a ceiling tile is faster. To ensure a reliable installation, please follow these steps carefully. Steel Backcan 1. Preparation Determine the correct mounting hardware for your particular ceiling construction (see diagram 2). Attachment Screws Tap Selector Loudspeaker Driver The C-Bracket spreads the clamping force of the mounting tabs, and strengthens the edge of the hole. The C-Bracket may be used without the tile rails. The Tile Rails spread the weight of the speaker across the ceiling. If the ceiling tile should fall out or break, the Tile Rails will catch onto the ceiling grid and prevent the speaker from falling. Secondary Support Tab NOTE: Due to the wide response of the AMPCS60, the low frequency vibrations generated may cause buzzing or rattling in some ceilings. Damping material under the Tile Rails or the edges of the ceiling tiles may be required. Removable Input Connector Rotating Mounting Tabs 2. [. . . ] Lift speaker into hole and tighten the 4 mounting tabs using a screwdriver (see diagram 5, 6). Select power Using a flat-bladed screwdriver, rotate the Tap Selector so the correct power setting is adjacent to the arrow. Note that there are separate 70V and 100V scales, depending on the amplifier being used (see diagram 7). 15 P. S v 60 70 P.

It may be desirable to leave the grilles off until commissioning is completed if adjustments are likely to be needed.
