1. 3 All this power and operating efficiency is available with an abso lute minimum of noise and distortion Excellent engineering and design of the audio stages have been blended with quality components to produce the PM 200 s impeccable specifications and superb sound quality The ultra linear semiconductors and circuitry used have the added benefit of reduc ing the need for power consuming negative feedback Just enough has been applied to the design to ensure linear operation and promote amplifier stability without coloring the sound or inhibiting the best performance The Carver Corporation understands that all this power and perform ance won t help if your amplifier doesn t work To that end the PM 200 employs a rugged mechanical design with heavy duty chassis components and features put together by people that know your amplifier must be reli able for years of active hard use Regardless of expertise or knowledge please read the rest of this owner s manual to take full advantage of the practical features and remarkable weight to output ratio which the PM 200 has to offer Follow all operation and installation instructions exactly FILL OUT THE WARRANTY CARD FIRST It s highly unlikely the PM 200 will ever need service if properly installed maintained and operated But should the unlikely occur the Warranty Card is a passport to Carver s One year Limited Parts Labor Warranty Repair The serial number date of pu2. available and fairly inexpensive and use a coding system for phase identification of the conductors Lamp cord has a small ridge or marking on the insulating jacket of one conductor some use silver and copper colored wires to note the difference between the conductors Rubber covered two conductor speaker wires use a color code on the insulating jackets of each conductor white black red black etc While speaker wires as light as 16 gauge can be used to connect the amplifier to the loudspeakers heavier gauged speaker wires should be used in any wire run over a few feet Heavier speaker wires minimize line losses and will improve the damping factor The speaker wires can be terminated at the amplifier by hard wiring to the binding posts spade lug terminals attached to the conductors or with dual banana plugs The banana plug is a good choice for most appli cations These connectors as we mentioned earlier have a locator tab along one side that s clocked so it denotes the negative side of the terminals and speaker wire Like the i firmly in their respective jacks Connect the speaker wires between the output terminals of the amplifier and the loudspeakers being careful to maintain proper speaker phasing The PM 200 should be connected to loudspeakers with an impedance of 4 ohms or greater ONLY in dual channel operation In the first sample system shown below the left main output of the mixing co

5. E MONO BRIDGED OPERATIONS AND CONNECTIONS The PM 200 may be used as a single channel amplifier by setting up and connecting it as follows Be very certain the power to the PM 200 is off and or the line cord unplugged 1 Mono Bridge Switch The Mono Bridge switch recessed between and below the XLR type input connectors must first be pushed in Use a narrow screwdriver or other thin device insulated to activate the switch by gently pushing it in This switch inverts the phase of the left channel input signal necessary to operate this amplifier in mono bridged mode Do not activate this switch with the amplifier operating Also check to see that it is out if you plan to go back to using the PM 200 in dual channel mode 2 Signal Connections In balanced or unbalanced modes signal must be equally supplied to both left and right channel inputs This may be done by using a patch cord between the two TRS 1 4 input jacks while the main drive signal is supplied through one of the XLR type connectors It doesn t matter which one since the input connectors are wired in parallel It s probably best to come into the right channel XLR type input connector This frees the left channel to feed signal to other amplifiers when cascading them Another option is using a Y cord to feed drive signals to the left right inputs on the amplifier 3 Loudspeaker Connections The PM 200 must be used with the loudspeaker impedances 8 ohms or greater when

7. cool down more quickly than any conventional amplifier since a shorter thermal time constant results from the reduced mass of the PM 200 about one third that of conventional amplifiers Less material bulk to build internal heat allows the PM 200 to be mounted flush with other conventional amplifiers and equipment in a rack without concern about overheating it or the ad jacent components However certain sensitive low level components might pick up noise or hum from the PM 200 or other high performance power amplifiers If this is a problem separate the components and amplifiers by as much as necessary to eliminate the noise Another option is installing a heavy Phreldiig plate between them for the same results When mounting equipment in a case or rack it s a good practice to install the heaviest components in the bottom of the enclosure This effectively lowers the case s center of gravity and promotes physical stability of the enclosure during handling and transportation Sm Ge ce POWERING THE PM 200 IN PORTABLE RACK INSTALLATIONS The PM 200 should be connected to an AC outlet or receptacle rated at no less than 400W If your sound system uses several PM 200s or other conventional amplifiers a multi receptacle power bar outlet strip or special power block should be used to ease the problem of finding enough common point outlets to safely power the complete sound system If you re going this route make sure it will handle the tota
8. ct space What makes all this and more possible is Bob Carver s design break through in power supply engineering concepts that has become the real key to the many benefits the PM 200 can offer the audio professional Years were spent in developing this proven design concept which is centered around a small lightweight power supply capable of processing and storing vast amounts of energy with amazing efficiency Instead of the massive transformers storage capacitors and heat sinks that contribute to conventional commercial amplifier size weight and cost the PM 200 uses a vastly superior method of electronic control in their place The most obvious benefit of magnetic field technology is the PM 200 s remarkably compact size and weight Conventional amplifiers capable of producing as much power can and usually do weigh two or three times as much as the PM 200 and occupy a lot of valuable rack space in an equipment rack or enclosure By contrast your amplifier takes up only two vertical rack spaces 3 1 2 inches and weighs just over 14 lbs That s less than many effects generators When it comes to output power the PM 200 can deliver over 100W RMS per channel into an 8 ohm loudspeaker impedance 150W per channel into a 4 ohm loudspeaker impedance and 350W into an 8 ohm loudspeaker impedance in mono bridged mode Amplifiers of that wattage rating are far larger heavier and often actually deliver less available headroom than the PM 200
