MAGNETIC FIELD

CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below the unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are located nearby. The field is strongest just above and below the unit.

If an equipment rack is used, we recommend locating the amplifier(s) in the bottom of the rack and the preamplifier or other sensitive equipment at the top.

FCC COMPLIANCE NOTICE

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

CAUTION: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

1 Welcome

The Crown® Macro-Tech ® 3600VZ professional power amplifier features Crown’s patented Variable Impedance (VZ ® ) power supply. This power supply, along with advanced semiconductor technology, enables the Macro-Tech 3600VZ to pack more power into a mere 3½ inches of vertical rack space than ever before. Because it’s a Macro-Tech, you have the added benefit of PIP ™ compatibility for access to custom input modules and ODEP ® protection to keep the show going long after other amplifiers would fail.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, the MA-3600VZ amplifier includes a number of features which require some explanation before they can be used to their maximum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

Grounded Bridge design delivers large voltage swings without stressing outputtransistors, resulting in lower distortion and superior reliability.

Patented ODEP (Output Device Emulation Protection) circuitry compensates for overheating and overload to keep the amplifier working when others would fail.

IOC® (Input/Output Comparator) circuitry immediately alerts of any distortion exceeding 0.05%, providing dynamic proof of distortion-free performance.

Articulated VZ power supplies for each channel provide excellent crosstalk characteristics and the best power matching to your load.

2 How to Use This Manual

This manual provides you with the necessary information to safely and correctly setup and operate your amplifier. It does not cover every aspect of installation, setup or operation that might occur under every condition. For additional information, please consult Crown’s

Amplifier Application Guide (available online at www.crownaudio.com), Crown Tech Support, your system installer or retailer.

We strongly recommend you read all instructions, warnings and cautions contained in this manual. Also, for your protection, please send in your warranty registration card today. And save your bill of sale—it’s your official proof of purchase.

3 Setup

3.1 Unpack Your Amplifier

Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation company immediately. Only you can initiate a claim for shipping damage. Crown will be happy to help as needed. Save the shipping carton as evidence of damage for the shipper’s inspection.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.YOU WILL NEED (not supplied):

• Input wiring cables

• Output wiring cables

Rack for mounting amplifier (or a stable surface for stacking)

WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instructions found at the beginning of this manual.

3.2 Install Your Amplifier

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with power switch in the “off” position and all level controls turned completely down (counterclockwise).

Use a standard 19-inch (48.3 cm) equipment rack. See Figure 3.1 for amplifier dimensions.

You may also stack amps without using a cabinet.

NOTE: When transporting, amplifiers should be supported at both front and back.

Figure 3.1 Dimensions

page 6

3.3 Ensure Proper Cooling

When using an equipment rack, mount units directly on top of each other. Close any open spaces in rack with blank panels. DO NOT block front or rear air vents. The side walls of the rack should be a minimum of two inches (5.1 cm) away from the amplifier sides, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel.

3 Setup

3.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and connectors. You may use banana connectors, terminal forks or bare wire for your output connectors (see Figure 3.5). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

Note: Binding post outputs on European models come with safety plugs installed to prevent European power-cord plugs from being inserted. The side entry positions for these connectors should therefore be used.

Using the guidelines below, select the appropriate size of wire based on the distance from amplifier to speaker.

Distance

Wire Size

up to 25 ft.

16 gauge

26-40 ft.

14 gauge

41-60 ft.

12 gauge

61-100 ft.

10 gauge

101-150 ft.

8 gauge

3.6 Wire Your System

3.6.1 Stereo Mode

Typical input and output wiring is shown in Figure 3.6.

INPUTS: Connect input wiring for each channel. Refer to Section 3.4 for input connector pin assignments.

OUTPUTS: Maintain proper polarity (+/-) on output connectors.

Connect positive (+) speaker lead to Channel 1 positive binding post of amp; connect negative

(–) speaker lead to Channel 1 negative binding post of amp. Repeat for Channel 2. Refer to Section 3.5 for output connector pin assignments. Make sure the Mode switch set to the “Stereo” position when operating in Stereo mode.

3.6.2 Bridge-Mono Mode

Typical input and output wiring is shown in Figure 3.7.

INPUTS: Connect input wiring to Channel 1. Refer to Section 3.4 for input connector pin assignments.

OUTPUTS: Connect positive (+) speaker lead to Channel 1 positive binding post of amp; connect negative (–) speaker lead to Channel 2 positive binding post of amp. Do not use the negative binding posts when operating in Bridge-Mono mode. Refer to Section 3.5 for output connector pin assignments. Make sure the Mode switch is set to the “Bridge” position when operating in Bridge-Mono mode.

NOTE: Turn down (full CCW) the Channel 2 level control when operating in BridgeMono mode, as the Channel 1 level control works both channels.
