WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.
Important Saf ety Instructions Please read all instructions and precautions carefully and completely before operating your Proceed power amplifier. 1. ALWAYS disconnect your entire system from the AC mains before connecting or disconnecting any cables, or when cleaning any component. 2. This product is equipped with a three-conductor AC mains power cord which includes an earth ground connection. To prevent shock hazard, all three connections must ALWAYS be used.
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.

Unpacking and Placement Unpacking Unpack your Proceed® Five Channel Amplifier and keep all packing m aterials for future transport. Shipment of the amplifier without the original packing material is not recommended, as it is heavy enough to make improvised packaging impractical. Locate and remove all accessory items from the cartons, and store teh cartons for possible future use. Carefully inspect the product for shipping damage. If you discover any, see your Proceed dealer immediately.
Operating Voltage The Proceed amplifier is factory-set for 100V, 120V, 220V, or 240V AC mains operation 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 regulations.) Make sure that the label on the rear panel of the amplifier indicates the correct AC operating voltage for your location. The operating voltage cannot be changed by the user, and any attempt to do so will void the warranty.
A Quick Start We recognize that many people are understandably eager to begin listening to their new components, and that reading the manual is often done (if at all) at a later time—perhaps while listening to music through the new product itself. We strongly recommend that you read this manual thoroughly. Fortunately, we can help you get some music up and running on your system quickly, so that you may begin enjoying your new amplifier while reading more about it.
7 SLOWLY RAISE THE VOLUME ON YOUR PREAMPLIFIER Congratulations! You 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.
Special Design Features Congratulations on your purchase of a Proceed amplifier! While your new amplifier is straightforward in its use, it includes several design features which are responsible 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.
power supply components during power-up, and switches off-line once the power supply has been charged. Home THX Audio System certification Lucasfilm, Ltd.® has established minimum standards for the performance of various components which may be used in their Home THX® Audio System.
2 five channel amplifier standby 3 power 1 Front Panel 1 POWER BUTTON Pressing this latching power button connects the amplifier to the AC mains, charges the power supply (which takes about five seconds), and places it in standby. Having a true standby function keeps the sensitive voltage gain stages warmed up and sounding their best at all times. Power consumption when in standby is less than 150 watts.
Note also that if the amplifier has been disconnected from the AC mains power by depressing the front panel power button, it cannot respond to a remote turn-on command from a control unit. 3 INDICATOR LIGHTS The power indicator light (above the small power button, below the large standby button) is normally either on or off, indicating whether AC power is being supplied to the amplifier.

These two RJ-45 communications ports also support the PHAST™ intercomponent communications protocols, greatly simplifying the design and installation of sophisticated home automation systems. They provide twoway communication with the home automation controller as to the amplifier’s current status, ensuring reliable execution of sophisticated turnon and shutdown macros. To use these ports, simply daisy chain the various Proceed products together.
If you are not using these turn-on inputs, you may leave them both empty of any plugs. 4 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: PUSH 2 1 3 Pin 1: Signal ground Pin 2: Signal + (non-inverting) Pin 3: Signal – (inverting) Connector ground lug: chassis ground These pin assignments are consistent with the standards adopted by the Audio Engineering Society.
7 Caution! 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. NEVER connect the amplifier output terminals to any device other than a loudspeaker. NEVER short-circuit the amplifier’s output terminals.
Bridged Operation Your 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.

3 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 output 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 connections should be side-by-side rather than one above the other.) Make sure these connection are snug and secure.
Biamplification In contrast to bridged operation (wherein two amplifier channels are “fooled” into behaving as a single, larger channel), biamplification makes use of two channels 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 loudspeakers support biamplification). Since each channel of the amplifier is delivering current into its load only over a limited range of frequencies (typically bass vs.
Care & Maintenance To remove dust from the cabinet of your amplifier, use a feather duster or a lintfree 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. Do not use excessive amounts of alcohol that might drip off the cloth and into the amplifier.

Obtaining Service We take␣ great pride in our dealers. Experience, dedication, and integrity make these professionals ideally suited to assist with our customers’ service needs. If your Proceed component must be serviced, please contact your dealer. Your dealer will then decide whether the problem can be remedied locally, or whether to contact Madrigal for further service information or parts, or to obtain a Return Authorization.
Specifications The correlation between published specifications and performance is unreliable. A list of numbers reveals virtually nothing. All technical measurements must be subject to qualitative as well as quantitative interpretation. Measurements of the Proceed amplifier 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 product.
