2.0 Before You Begin

Congratulations on your purchase of a new Bose® Professional Stereo Power Amplifier. It is backed bystate-of-the-artengineering and manufacturing techniques to bring you the best in quality craftsmanship and reliable performance.

2.1 Unpacking the amplifier

Carefully unpack your amplifier. Keep the original carton and packing materials for possible future use. Check for any visible signs of damage. If the amplifier appears damaged, do not try to use it. Notify the Bose Product Support or your authorized Bose Professional Products dealer.

3.0 The Bose Model 1800-VIand1600-VIProfessional Stereo Power Amplifiers

The Bose Model 1800-VIand1600-VIProfessional Stereo Power Amplifiers are specially designed for professional sound applications. Their rugged construction and low profile allow each amplifier to sustain the abuses of the road with reliability andspace-savingeconomy. Also, their accurate sound and ample power make these amplifiers ideal for critical studio applications.

The 1800-VIamplifier is rated at 600 watts per channel into 4 ohms and 450 watts per channel into 8 ohms. In bridged mono operation, it is rated at 1400 watts into 8 ohms.

The 1600-VIamplifier is rated at 325 watts per channel into 4 ohms and 240 watts per channel into 8 ohms. In bridged mono operation, it is rated at 700 watts into 8 ohms.

The sophisticated protection circuits designed into each amplifier will protect your system from unexpected faults. They also protect each amplifier from excessive temperature, continuous current limiting, and shorted outputs.

The balanced inputs of each amplifier use a high quality, high common-moderejection differential amplifier for exceptional hum and noise rejection.

In addition, both the 1800-VIand the1600-VIamplifiers are equipped with an input board that allows different equalization for each channel (provided the correct equalization card is installed). Equalization cards (EQ cards) are available for Bose 402®, 502®A, 502B, and 802® loudspeakers.

A sample setup might involve one Model 1800-VIamplifier driving two channels of 802 loudspeakers in stereo mode. A second Model1800-VIcould be added to drive a 502B module. Alternatively, just one amplifier could be used to drive the 802 loudspeakers on one channel and the 502B module on the other channel. Many configurations are possible using the four loudspeakers above. This flexibility can be achieved by installing the EQ cards for the desired setup.

4.1 Location and general precautions

Locate the unit where it will not be exposed to rain or moisture. If fluid or a foreign object enters the unit, disconnect the power plug. Do not pull by the cord; grasp the plug firmly. Contact an authorized dealer or service center.

Place the unit where it will be protected from heat and allow adequate ventilation. Place it away from direct heat sources, such as heating vents and radiators. Make sure the ventilation holes are not covered and air can circulate freely behind, beside, and above the unit.

4.2 Mechanical considerations

Either amplifier requires two 3.5" rack space units with a 15" depth inside the rack (including the rear supports). Use four screws with washers to prevent marring the front panel. Neoprene rubber washers are a good choice because they grip the screw head and prevent the screws from backing out in the event of vibration or if the unit is transported.

4.2.1 Rear support for road applications

If either unit is rack-mountedand the rack is transported, you must mechanically support the rear of the amplifier. You can place a shelf across the rear of the amplifier or brackets in such a way as to support the rear of the unit. This practice is recommended for all electronic instruments.

4.3 Thermal considerations

When either amplifier is used free-standing,no thermal considerations are necessary other than keeping the ventilation holes open.

If the unit is rack-mounted,allow for adequate ventilation exits in front of and behind the amplifier. When several amplifiers are mounted together in a rack, you may need to provide air inlets from the outside of the rack.

The unit is fan cooled. The fan is internally mounted so that it draws air in from the front and exhausts it out the rear. This allows cool air from outside the amplifier to flow over and cool the power supply components located in front of the heatsinks.

These amplifiers may be stacked directly on top of each other without spacer panels. If an amplifier is used with other amplifiers, be sure the heat output from each amplifier does not interfere with the ventilation of the others.

4.4 AC power considerations

Be sure to plug your amplifier into an outlet capable of supplying the correct voltage specified for your model. Check to be sure there is enough current to allow full-poweroperation of all the amplifiers in your system.

The power plug serves as the Main Disconnect device and should always be easily accessible after installation.

The current demand of a power amplifier varies depending on the impedance of the load, the output level of the amplifier, and the crest factor and duty cycle of the program material. For example, consider typical conditions reproducing rock music, with both channels driven into 4 ohms to the point where musical peaks are just at the clipping point.

Under these conditions, the Bose® Model1800-VIamplifier requires an average of 6.7 amps for 120V versions (3.5 amps for 230V versions).

The Bose Model 1600-VIamplifier requires an average of 4.2 amps for 120V versions (2.2 amps for 230V versions).

4.5 Magnetic leakage considerations

You can mount the Bose Model 1800-VIor1600-VIamplifier without concern for magnetic flux leakage. However, it is not a good idea to mount any power amplifier near a microphone input transformer or magnetic storage media.

4.6Input wiring

You may use 1/4" phone jacks, XLR connectors, and quick connect terminal block connectors for the input signal with either unbalanced 2-conductoror balanced3-conductorcables. Use shielded coaxial cable to conduct the signal from the source (mixer, equalizer, CD player) to the amplifier.

4.6.1 Balanced operation

For the 1/4" phone jack, use a 3-conductorTRS 1/4" phone plug. The tip of the plug carries the + (hot,non-inverting)side of the signal. The ring carries the – (low, inverting) side of the signal. The sleeve is ground (see Figure 1).

Figure 1

1/4" phone jack balanced input connection.

For the XLR, use a male XLR connector. Pin 2 carries the + (hot, non-inverting)side of the signal. Pin 3 carries the – (low, inverting) side of the signal. Pin 1 is ground (see Figure 2).

Figure 2

XLR balanced input connection.

4.0 Installation

For the quick connect terminal block, use the female connector provided. Pin 3 carries the + (hot, non-inverting)side of the signal. Pin 2 carries the – (low, inverting) side of the signal. Pin 1 is ground (see Figure 3).

Figure 3

Quick connect terminal block balanced input connection.

If you are using the standard input module for either amplifier, the polarity of the balanced inputs can be reversed by changing four jumpers located on the input board, just behind the input connectors. If you are using the ACM-1module for either amplifier, the polarity cannot be reversed. Refer to page 12 for a description of the different modules.

4.6.2 Unbalanced operation

For the 1/4" phone jack, use a 2-conductor(tip-sleeve)1/4" phone plug. The tip of the plug carries the signal and the sleeve is ground. The ring connection in the jack is automatically grounded by the sleeve (see Figure 4).

4.0 Installation

For the XLR, pin 2 carries the + (hot, non-inverting)side of the signal, and pin 1 is ground. To reference the input differential amplifier for the correct gain, short pin 3 to pin 1 (see Figure 5).

Figure 5

1/4" XLR unbalanced input connection.

For the quick connect terminal block, pin 3 carries the + (hot, non-inverting)side of the signal, and pin 1 is ground. Short pin 2 to pin 1 in order to reference the input differential amplifier for the correct gain (see Figure 6).

Figure 6

Note

The gain remains the same regardless of whether the input is balanced or unbalanced.
