Page 3: Important Safety Instructions
Important Safety Instructions Please read all instructions and precautions carefully and completely before operating your Proceed power am- plifier. 1. ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting any cables, or when cleaning any component. - Page 4 From all of us at Madrigal Audio Laboratories, thank you for choosing the 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.

Page 6: Unpacking And Placement
Locate and remove the heavy gauge AC power cord, which is tucked into a cardboard slot within the box. Y our Proceed AMP may be placed either near the preamplifier/control center or Placement 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 The Proceed AMP 2 and AMP 3 are factory-set for 100V , 120V , 220V , or 240V AC mains operation at either 50 or 60Hz, according to the country for which the unit was manufactured. (230V in European Union countries, in compliance with CE regulations.) Make sure that the label on the bottom of the AMP indicates the... -
Page 8: A Quick Start
CONNECT YOUR SPEAKERS TO THE AMP Each channel of the Proceed AMP 2 and AMP 3 is supplied with two sets of binding posts to facilitate bi-wiring. Using either the top or the bottom set of red and black binding posts, connect speaker wire from the AMP to your loudspeakers. - Page 9 TURN ON THE AMP BY PRESSING THE POWER BUTTON Pressing the latching power button on the front panel of the AMP 2 and AMP 3 will connect the amplifier to the AC mains. If the indicator light does not light, the amplifier is either not receiving AC power or its pro- tection circuitry has been engaged.

Page 10: Special Design Features
The combination of an “overbuilt” design specification and extraordinary attention 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 DC (direct current) at the output or an unsafe operating temperature. In either case, a power relay will cause the amplifier to be disconnected from the AC mains. -
Page 11: Home Thx Audio System Certification
THX certification. Both the Proceed AMP 2 and AMP 3 are certified for use in Home THX audio systems. In these products, Madrigal engineers have created powerful, versatile and extraordinarily musical power amplifiers, using the technology and design methodology for which they have become so well known. -
Page 12: Front Panel
Proceed control unit such as the PAV , PRE, or even the CDP . Power consumption in mode is extremely small— standby just a few watts for the circuitry which controls the turn-on procedure. -
Page 13: Rear Panel
AC receptacle on the rear panel of the AMP , then to the AC mains outlet. Warning! The Proceed AMP has been safety-tested and is designed for operation with a three-conductor power cord. Do not defeat the “third pin” or earth ground of the AC power cord. -
Page 14: Remote Turn-On Tip Polarity
" “mini” jack above the AC mains receptacle on the rear panel allows remote-controlled turn-on (that is, toggling between operate and standby) of the Proceed AMP . This remote “trigger” will be operated by a 3–12 volts DC positive-polarity pulse, of at least 100 milliseconds dura-... - 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 AMP . If not, wire the cables so that the ap- propriate output pin connects to the equivalent input pin.
- Page 16 SINGLE-ENDED INPUTS These RCA connectors accept single-ended inputs from preamplifiers with single-ended (RCA) outputs. Connect the left-channel single-ended outputs of your preamplifier to the left-channel single-ended input on the AMP . Repeat for the remaining channel(s).

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 opera- tion first. -
Page 18: Balanced Bridged Input Connection
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 balanced input signal, follow these steps: DISCONNECT YOUR AMPLIFIER FROM EVERYTHING Start with your amplifier totally disconnected from inputs, outputs, and AC power. -
Page 19: Single-Ended Bridging
CONNECT THE BALANCED BRIDGING OUTPUT ADAPTER TO TWO BLACK OUTPUT TERMINALS All Proceed amplifiers have two sets of output terminals per channel, wired in parallel (for convenience when biwiring). You may use either of the black output terminals. Connect one end of the Balanced Bridging Output... -

Page 22: Biamplification
Biamplification In contrast to bridged operation (wherein a two channel amplifier is “fooled” into behaving as a single, larger amplifier), biamplification makes use of a two-channel amplifier to drive different portions of a single loudspeaker. As with bridging, it offers a modular way of increasing the overally performance of your system (if your loudspeakers support biamplification). -
Page 23: Biamping Wiring Diagram
Vertical biamping allows the amplifier to be placed extremely close to each speaker, keeping speaker leads as short as possible. To facilitate biamping, all Proceed power amplifiers have the same voltage gain and input sensitivity. Because of this fact, you should not have to con- cern yourself with adjusting the relative volumes of the bass and treble sec- tions of your loudspeakers—if they sounded good with a single amplifier, they... -
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
A list of numbers reveals virtually nothing. All technical measurements must be subject to qualitative as well as quantitative interpretation. Measure- ments of the Proceed AMP yield excellent results by any standards. However, only those specifications that apply to its actual operation are included here. All specifications are subject to change at any time, in order to improve the prod- uct. -
