Functional Descrip tion The AT60 1 2 is a 1 2-channel, 6-zone pow er amplifier designed to pro vide audiophile-quality sound in multi-room installations. The AT60 12 consists of six 2-channel modules (DMC 4 ). Each zone ’s volume (gain) can be remotely adjusted via a “dr y” 3-wire connection from control devices such as Crestron, Xantech, Pha[...]

Pr ecautions The amplifier is a wideband design with substantial power output capability . Cert ain precautions must be t ak en to ensure proper operation. 1 . Nev er expose the unit to moisture. 2. Nev er plug an input cable into the amplifier while the amplifier is turned on. 3. Nev er apply the “thumb test” (touching the “hot” lead of th[...]

Saf e ty Ins tructions W ARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. Read all the safety and operating instructions before connecting or using this unit. All warnings on the unit and in this operating manual should be adhered to. All operating and use instr uctions should be follo wed. Do not u[...]

No tes On “Hum” With t he g ro wing sophistication of home theater systems, the potential for ground loops is enor mous. Do not automatically assume that one or more of y our components are at fault, or even defectiv e. Lately , one of the bigges t culprits is the Cable-T V incoming signal line. Almost 1 00% of t he cases where hum has been a p[...]

Cooling W ARNING: AN AMPLIFIER’S PERFORMANCE MAY DETERIORA TE IF IT O VERHEATS. TEMPERATURE AND VENTIL ATION ARE KEY F A CTORS IN PROPER OPERATION. NOT ONLY SHOULD Y OU PRO VIDE ENOUGH SP ACE AROUND THE UNIT , BUT ALSO ENSURE THAT AIR CAN FLO W FREEL Y AND ESC APE FROM THE AMPLIFIER’S SURROUNDINGS. Placement During normal home operation, the he[...]

Loudspeak er R atings Virtually any loudspeakers can be connected to, and dr iv en by the AT60 12. The AT60 1 2 can drive low impedance speak ers at more than adequate power levels with no dif f iculty . Many loudspeak er systems which are nominally rated at 4 Ohms will drop in impedance in some par ts of their frequency rang e, of ten to 2 Ohms. Y[...]

Cir cuitr y The amplifier is totally complementar y from input to output. This is achieved by using dual-differential input st ag es. Full-complimentary push-pull pre-drivers follow the input stages. These in turn are direct-coupled (all stages af ter the A C coupled input are DC coupled) to two push-pull drivers. All stag es up to this point are o[...]

General Maintenance And Ser vice Great care has been taken to ensure that your amplifier is as f lawless in appearance as it is in performance. The front panel is f inished with a high-grade anodizing process for durability as well as beauty . It is best cleaned with a sof t cloth dampened with a mild solution of liquid deterg ent and water . CAUTI[...]
