cr16/mc58 companion products the mcintosh products shown at right are logical companions for the cr16/mc58 separate literature is available check with your mcintosh dealer for late additions wk2 wk3 wk4 keypad controllers and r649 ir sensor the wall-mount illuminated keypads enable pushbutton operation and include ir sensors that relay commands from handheld remotes the cr16 can accommodate as many as four keypads or ir sensors in each of its four zones see the separate mcintosh system accessories literature for more on keypads and ir sensors in addition an rs-232 port makes the cr16 compatible with popular touchscreen remotes from crestron and panja rct4 remote translator the translator allows non-mcintosh components to be operated with a mcintosh ir remote or keypad controller it connects to the data outputs on the cr16 hc1 home controller the hc1 connects to the cr16 s home data output and allows remote operation of other home devices such as lights and movie screens pc3 ac power controller the pc3 provides a total of 14 ac outlets 11 switched 3 unswitched for automatic ac control of zone amps audio sources and video components it connects to a multipin jack on the cr16 pc4 ac power control the pc4 provides five outlets four switched for turning non-mcintosh components on and off automatically when it is connected to the power control output of a control center or integrated amplifier mr85 am/fm tuner with dual tuners ideal for multiroom systems the mr85 is available with a second tuner the tm1 module that operates independently a thoroughly engineered broadcast monitor the mr85 reveals the upper limits of am and fm performance the supplied raa1 am antenna can be positioned away from sources of interference e.g tv sets fluorescent lights for greatly improved am quality mx132 a/v control center processor one cable from the mx132 to the cr16 will integrate a mcintosh home theater with a mcintosh multizone system this lets the two systems share one group of source components academy series loudspeakers the academy loudspeakers satisfy the often contradictory demands of pure music versus movie sound all academy loudspeakers use the acclaimed ld/hp ® driver ­ which significantly reduces bass distortion while increasing power handling the compact ht5 has a footprint less than 10 inches square the ls320 features arched bridge truss construction that is virtually immune to vibrations that distort sound a special tweeter plate reduces edge diffraction cancellation and is mounted on traditional mcintosh screened black glass the ws320 is the wall-mount sibling of the ls320 and comes in a paintable white finish at 400 watts the ps112 is mcintosh s most powerful amplified subwoofer it features arched bridge truss construction and a screened black glass control panel wk2 wk3 wk4 keypad controllers and r649 ir sensor rct4 remote translator hc1 home controller featured technologies cont d below 2 and prevent any clipping distortion thanks to an optical resistor power guard acts literally at the speed of light producing absolutely no audible side effects an amplifier with power guard will actually deliver clipping-free output well above its rated power sentry monitor® current protection sentry monitor continually senses the voltage and current of the output stage and confines it to a safe limit sentry monitor does not limit power output pc3 pc4 ac power controllers mr85 am/fm tuner a -20 -40 l o g -60 0 db b -20 -40 l o g -60 0 db c -20 -40 l o g -60 0 db -80 -90 20hz 200hz 2khz -80 -90 20hz 200hz 2khz -80 -90 20hz 200hz 2khz the patented mcintosh power guard in the mc58 provides real-time clipping protection without affecting power output or sound quality a test signal b overdriven amp without power guard produces severe clipping c overdriven amp with power guard produces no clipping thermal cutout if the cooling air is blocked and the power transistors become too hot thermal cutouts protect against overheating until the amp cools turn-on delay this circuit delays operation for about two seconds after turn-on in order to avoid any pops or thumps generated as other equipment turns on soft start inrush protection thermistors in the power transformer act as a cushion against inrush current eliminating component stress during turn-on soft start is one of many design details that contribute to the remarkable longevity of mcintosh equipment ht5 ls320 ws320 ps112 why choose mcintosh consumer electronics products usually are viewed as shortterm investments because they don t last or they quickly become obsolete in some way but behind every mcintosh is a fifty-year heritage of excellence proudly carried forward by every employee no production lines no price-point engineering no planned obsolescence mcintosh equipment is made to sound better and last longer when customers are presented with mcintosh products criteria they have been conditioned to overlook ­ reliability longevity craftsmanship ease-of-use adaptability pride of ownership ­ suddenly leap to the top of their list the choice then becomes clear there is nothing like a mcintosh.
