[. . . ] Five Channel Amplifier PR O C E E D 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. REFER SERVICING TO QUALIFIED PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Marking by the "CE" symbol (shown left) indicates compliance of this device with the EMC (Electromagnetic Compatibility) and LVD (Low Voltage Directive) standards of the European Community. The information contained in the manual is subject to change without notice. The most current version of this manual will be posted on our web site at http://www. madrigal. com. 2 Important Safety 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. This product is equipped with a three-conductor AC mains power cord which includes an earth ground connection. [. . . ] When the indicator light is glowing red, the unit is in standby. If the standby indicator light is completely off, the amplifier is not receiving power. Check your AC connections and the rear-panel AC fuse. 13 PR O C E E D trigger inputs PUSH R five channel amplifier by MADRIGAL AUDIO LABS made in u. a. outputs outputs outputs outputs outputs PUSH PUSH PUSH ~ac mains right front right rear center left rear left front 123 4 5 6 PUSH communication ports input select Rear Panel input select input select input select input select 7 Caution! Turn the volume on your controller/preamplifier all the way down before attempting to connect anything to your Proceed Five Channel Amplifier. 1 AC MAINS RECEPTACLE Connect the AC power cord (included in the accessory pack) to the IECstandard AC receptacle on the rear panel of the amplifier, then to the AC mains outlet. Warning! Your Proceed amplifier 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. 2 COMMUNICATION PORTS These RJ-45 communications ports provide for sophisticated inter-component communications within the context of a Proceed system, allowing the multichannel controller to toggle the amplifier between operate and standby as needed, without forcing the user to turn the amplifier on separately. Since this communication link provides two-way communication, it is more reliable and preferred over simpler DC trigger hookups (although we support DC triggers as well, since their use is so widespread). 14 These two RJ-45 communications ports also support the PHASTTM 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. 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. Modular cables and connectors are used throughout the world for both telecommunications and computers, and are widely available at low cost. The connectors are crimped on to the ends of the cable such that pin 1 at one end is connected to pin 1 at the other end. Such a "straight-through" connection is (counter-intuitively) made by introducing a 180° twist in the cable between the two ends, as shown below. communication cable from Proceed PDSD or AVP To Five Channel Amplifier Locking tab Locking tab 3 REMOTE TURN-ON ("TRIGGER') JACKS Two 1/8" "mini" jacks above the AC mains receptacle on the rear panel allows remote-controlled turn-on (that is, toggling between operate and standby) of the Proceed amplifier. These remote "triggers" will be operated by the presence of 5­12 volts DC, with tip polarity as shown below: Remote turn-on tip polarity ­ + 5-12 volts, positive tip polarity The presence of a suitable DC voltage will cause the amplifier to be fully on; the absence of such a voltage will cause it to enter standby. Y our Proceed dealer can help you take advantage of these design features to maximize your system's versatility. Since these trigger inputs are wired in parallel, you can go into one and out of the other to facilitate a "daisy-chain" of turn-on triggers (should you have additional products that need to be controlled in this manner). Special note: if this method of control is used for the amplifier(s), the last mini-jack in the chain must be terminated with a dummy 1/8" plug [that is, an empty plug must be inserted into the final 1/8" (3. 5 mm) jack]. Even if only a single amplifier is controlled in this fashion, the "extra" mini-jack must be terminated. 15 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 21 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 Refer to the operating manual of your balanced. output preamplifier to verify that the pin assignments of its output connectors correspond to your Proceed amplifier. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin. If you are planning to use balanced connections between your preamplifier and any particular channel of the amplifier, select the balanced input by sliding the input select switch (see Item 5, below) toward the XLR input. [. . . ] A copy of the original bill of sale will serve to verify warranty status. Please include it with the unit when it is brought in for warranty service. Warning! All returned units must be properly packaged (preferably in their original packing material), and the proper return authorization numbers must be marked on the outer carton for identification. If the packaging to protect the unit is, in our opinion or that of our dealer, inadequate to protect the unit, we reserve the right to repackage it for return shipment at the owner's expense. Neither Madrigal nor your dealer can be responsible for shipping damage due to improper (that is, non-original) packaging. Y our dealer can order a new set of shipping materials for you if you need to ship your component and no longer have the original materials. [. . . ]
