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 FEATURES INSTALLATION SPECIFICATIONS 2 3 8 THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL AUS, EUR, USA Copyright 7 Nov 2005 Rev A: 7 Nov 2005 This symbol is intended to alert the user to the presence of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. 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. Cut hole Determine the speaker position, taking into account any obstructions in the ceiling space. Note that clearance of 185mm above the lower face of the ceiling is required. The C-Bracket can be used as a template. Perforated Press-In Grille PAGE 2 AMPCS60 INSTALLATION & OPERATION MANUAL AMPCS60 INSTALLATION & OPERATION MANUAL PAGE 3 INSTALLATION INSTALLATION 3. [. . . ] It may be desirable to leave the grilles off until commissioning is completed if adjustments are likely to be needed. Diagram 7 30 7. 5 60 CAUTION: To avoid distortion or equipment damage, carefully consider the power ratings of both amplifiers and speakers. Only 2 speakers at 60W will fully load a 120W amplifier, but note that each will be producing more than 106dB direct Sound Pressure Level at the listener when installed in a 3m ceiling!Dropping to the 15W tap allows 8 speakers to be driven by the same amplifier, each producing 100dB SPL. If 60W @ 70V is selected, but 100V line amplifier is connected, the speaker will draw up to 120W and damage is likely. 0v 7. [. . . ]
