  • Page 3: Important Safety Instructions

    Important Safety Instructions Please read all instructions and precautions carefully and completely before operating your Proceed power amplifier. ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting any cables, or when cleaning any component. This product is equipped with a three-conductor AC mains power cord which includes an earth ground connection.
  • Page 4 From all of us at Madrigal Audio Laboratories, thank you for choosing this Proceed power amplifier. A great deal of effort went into the design and construction of this precision device. Used properly, it will give you many years of enjoyment.

    Carefully inspect the product for shipping damage. If you discover any , see your Proceed dealer immediately . Y our Proceed amplifier may be placed either near the preamplifier/control center Placement or near the loudspeakers. It may be placed on a shelf or in a cabinet where it is convenient to operate.
  • Page 7: Operating Voltage

    Operating Voltage This Proceed amplifier is factory-set for 100V , 120V , 220V , or 240V AC mains op- eration at either 50 or 60 Hz, according to the country for which the unit was manufactured. (230V in European Union countries, in compliance with CE regu- lations.) Make sure that the label on the rear panel of the amplifier indicates the...
  • Page 8: A Quick Start

    It does not need to be turned off—merely turned down. SELECT “XLR” OR “RCA” WITH THE “INPUT SELECT” SWITCHES Each channel of the Proceed HPA 3 Power Amplifier has both balanced (XLR) and single-ended (RCA) inputs, with a small switch between the two connectors to select between them.
  • Page 9 SLOWLY RAISE THE VOLUME ON YOUR PREAMPLIFIER Congratulations! Y ou should now be able to enjoy your favorite music while reading the rest of this manual. (Please, do read the rest of this manual. It contains much valuable information about your new amplifier which we could not possibly fit onto these two pages.)
  • Page 10: Special Design Features

    The combination of an “overbuilt” design specification and extraordinary atten- tion to detail in manufacturing improves performance, reliability , and longevity . Y our Proceed amplifier will shut itself down if it senses either the presence of Extensive protection either DC (direct current) or a short circuit at the output, or any unsafe operating temperature.

    AC outlet, it cannot respond to a remote turn-on command from a control unit. If you wish the amplifier to turn on and off via the Proceed communi- cations bus (or by a DC trigger), the amplifier needs to be in standby , with this button engaged.
  • Page 12 Note that pressing the button has no effect until after the power standby supply is fully charged. Note also that if the amplifier has been disconnected from the AC mains power by depressing the front panel button, it cannot respond to a power remote turn-on command from a control unit.

  • Page 14: Communication Cable

    To use these ports, simply daisy chain the various Proceed products to- gether. The modular cable needed for the connection may be purchased from your Proceed dealer. It may also be easily and inexpensively made to length using two modular connectors and the appropriate length (up to 100 feet/30 meters) of flat, eight conductor cable.
  • Page 15 Audio Engineering Society . Refer to the operating manual of your balanced- output preamplifier to verify that the pin assignments of its output connec- tors correspond to your Proceed amplifier. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.

  • Page 17: Bridged Operation

    Bridged Operation Y our Proceed amplifier has been designed to be extremely versatile. Should your needs change or grow over time, you may wish to add additional power by one of two means: Bridging, or Biamping. We will discuss bridged operation first.

    CONNECT THE BALANCED BRIDGING INPUT ADAPTER TO THE INPUTS Connect the two male XLRs to two adjacent inputs on your amplifier, not- ing which XLR is marked red and which is black. The channel with the red, normal input will later be connected to the red, positive terminal of your loudspeaker.
  • Page 20: Single-Ended Bridging Kit

    Failure to establish a common ground reference between the two channels can damage your amplifier by forcing significant currents to flow where they do not belong! To bridge your Proceed amplifier using a single-ended (RCA) input signal, follow these steps:...
  • Page 21 DISCONNECT YOUR AMPLIFIER FROM EVERYTHING Start with your amplifier totally disconnected from inputs, outputs, and AC power. It is always best to power down an amplifier before changing connec- tions; here you are changing its basic configuration, making it essential. CONNECT THE SINGLE-ENDED BRIDGING INPUT ADAPTER TO THE AMP’S INPUTS Connect the two male XLRs to two inputs of your amplifier, noting which...
  • Page 22: Biamplification

    Biamplification In contrast to bridged operation (wherein two amplifier channels are “fooled” into behaving as a single, larger channel), biamplification makes use of two chan- nels to drive different portions of a single loudspeaker. As with bridging, it offers a modular way of increasing the overall performance of your system (if your loud- speakers support biamplification).
  • Page 23 The loudspeaker’s internal crossover continues to di- vide the frequencies appropriately among the various drivers. To facilitate biamping, all Proceed power amplifiers have the same voltage gain and input sensitivity. We even adjust for the difference between single-ended and balanced signal levels, should you have to mix the two.
  • Page 24: Care & Maintenance

    Care & Maintenance To remove dust from the cabinet of your amplifier, use a feather duster or a lint- free soft cloth. To remove dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Dampen the cloth with alcohol first and then lightly clean the surface of the amplifier with the cloth.
