[. . . ] 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. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. LIMITED WARRANTY Your Carvin product is guaranteed against failure for ONE YEAR unless otherwise stated. Carvin will service and supply all parts at no charge to the customer providing the unit is under warranty. Carvin assumes no responsibility for horn drivers or speakers damaged by this unit. This warranty does not cover, and no liability is assumed, for damage due to: natural disasters, accidents, abuse, loss of parts, lack of reasonable care, incorrect use, or failure to follow instructions. [. . . ] Carvin uses precision 6063 T-5 aluminum high ratio heat sinks that are extruded for massive amounts of cooling. LOSE THE WEIGHT. . . NOT THE PERFORMANCE For some companies weight reduction means cost reduction. Toroids deliver massive amounts of "on demand" current for continuous 2 ohm operation. This gives the power supply a solid foundation, yielding more headroom for the largest subwoofer application. Not only do toroids deliver high current, but they are known for reducing stray magnetic fields eliminating hum & noise. This is especially important for the recording industry. DISTORTION-FREE LIMITERS While most amps do not offer built-in limiters, this is an important feature to look for. The purpose of a limiter is to hold down peaks so the amp won't distort even with extra hot input signals (this protects your expensive speakers). In addition, a well designed limiter can increase your amp's average output as much as 3 db. Part of Carvin's design uses the more expensive, distortion-free linear "opto isolators". Unlike amps that use FET controlled limiters which can inject small amounts of distortion, the HT Series limiters keep your sound pure and uncolored!FRONT PANEL & CONNECTING UP The HT760M features front panel signal, peak and protect LEDs which let you monitor the status of the amp easily. Also, both channels use precision 41 detent level controls allowing you to see your settings at a glance. The main features are the two 9-Band graphic equalizers that easily allow fine tuning of your sound or balancing out and elimitaing feedback on a monitor system. Balanced 1/4 phone & XLR input jacks are used to eliminate hum & noise. Speaker outputs feature 1/4" jacks & heavyduty binding posts that accept up to 50 amp #7 speaker wires. The rear professional accessory group offers a GROUND switch to remove the chassis ground from the XLR input, a Parallel input switch connects the inputs of both channels together eliminating Y connectors and allowing amp patching in multiple amp systems. The accessory group also features a bridge mode switch for delivering full power into a 70V distribution system and a limiter ON/OFF switch that gives you the choice of using the internal limiter circuitry.

[. . . ] Use the two center RED binding posts for BRIDGE speaker connections (see 15 BRIDGE MODE). 15. BRIDGE MODE--25V/70V DISTRIBUTION SYSTEMS The "DCM" Series can be operated in bridge mode if you require a 25V / 70V distribution speaker system or a high powered mono (single channel) amp. With your amp off, push in the rear (recessed) BRIDGE switch after you have made your speaker connections to the rear center RED binding posts (ch 1 is + and ch 2 is ). No other speaker connectors or binding posts can to be used at the same time!". [. . . ]
