PRECAUTION ® Five Channel Amplifier and keep all packing m aterials Note that adequate clearance for the AC cord and connecting cables must be left behind your amplifier. We suggest leaving at least three inches of free space behind your amplifier to allow all cables sufficient room to bend without crimping or undue strain. -

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 Five Channel 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.

Page 10: Special Design Features
Special Design Features Congratulations on your purchase of a Proceed amplifier! While your new ampli- fier is straightforward in its use, it includes several design features which are re- sponsible for its outstanding performance. A few of these are given below. Multiple power supplies Unlike other multichannel amplifiers, your new amplifier maintains outstanding isolation and independence among its five channels. -

BALANCED AUDIO INPUTS Accepts signals from preamplifiers with balanced outputs via high quality XLR connectors. The pin assignments of these XLR-type female input connectors are: Pin 1: Signal ground PUSH Pin 2: Signal + (non-inverting)
- Page 17 SPEAKER OUTPUTS & BINDING POSTS The Proceed amplifier is equipped with gold-plated, high-current binding posts for output termination to a loudspeaker system. To take full advantage of the AMP’s sonic quality, we recommend using high-quality speaker cable; see your Proceed dealer. Caution! NEVER connect the amplifier output terminals to any device other than a loudspeaker.

Page 18: 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. Bridging Explained Bridging refers to the act of reconfiguring the circuitry in two channels of your amplifier to act as though it were a single, much larger amplifier. -
Page 19: Balanced Bridging Kit
Balanced Bridging Kit The “normal” leg of the Madrigal Balanced Bridging Input Adapter will be marked with a red stripe to indicate positive polarity, and the inverted leg will be marked with a black stripe to indicate inverted polarity (corresponding to the red and black terminals of your loudspeaker). -
Page 20: Single-Ended Bridging
If your preamplifier has only single-ended (RCA) outputs, a few details of Single-Ended Bridging bridged operation will differ from the discussion above, all pertaining to the con- nection of the preamp to the bridged amplifiers. For this discussion, we will as- sume that you are using a Madrigal Single-Ended Bridging Kit for each channel to be bridged. -
Page 21: Single-Ended Bridging Kit
Single-Ended Bridging Kit The “normal” leg of the Madrigal Single-Ended Bridging Input Adapter will be marked with a red stripe to indicate positive polarity , and the inverted leg will be marked with a black stripe to indicate inverted polarity (corresponding to the red and black terminals of your loudspeaker). - Page 22 CONNECT THE SINGLE-ENDED BRIDGING OUTPUT ADAPTER TO TWO SIDE-BY-SIDE BLACK OUTPUT TERMINALS Connect one end of the Balanced Bridging Output Adapter to a black out- put terminal on one side of the amplifier, and then connect the other end to a black output terminal on the other side of the amplifier. (The two con- nections should be side-by-side rather than one above the other.) Make sure these connection are snug and secure.

Page 23: 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 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. -

Page 27: Specifications
Specifications The correlation between published specifications and performance is unreliable. A list of numbers reveals virtually nothing. All technical measurements must be sub- ject to qualitative as well as quantitative interpretation. Measurements of the Pro- ceed amplifier yield excellent results by any standards. However, only those speci- fications that apply to its actual operation are included here. -
