English 4.0 Installation 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 ventila- tion holes are no

4.0 Installation 4.6 Input wiring You may use 1/4" phone jacks, XLR connectors, and quick connect terminal block connectors for the input signal with either unbalanced 2-conductor or balanced 3-conductor cables. 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-conductor TRS 1/4" phone plug. The tip of the plug carries the + (hot, non-inverting) side of the signal. The rin

English 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

English 4.0 Installation 4.7 Input sensitivity The amplifier input sensitivity is set to 0.775V rms for rated output. To reduce the sensitivity by 6 dB to 1.5V rms, simply remove JP100(CH1) and JP200(CH2), located on the main amplifier board (see Figure 7). Figure 7 Input sensitivity modification. 11

4.0 Installation 4.8 Output wiring Use heavy gauge wire for speaker connections. The greater the distance between the amplifier and the speakers, the larger the diameter the wire should be. This will minimize power losses across the wire and improve damping of the speaker. Wire thickness specifications (gauges) get larger as the wire gets thinner. So a 14-gauge wire is thicker than 18-gauge wire. Use the following chart as a guide. Wire Length Gauge of Wire Up to 15' 18 gauge 15' to 25'

5.0 Operation ® 5.1 Using the Bose Model 1800-VI or 1600-VI Professional Stereo Power Amplifier Once you have installed and wired the amplifier, follow these tips to get the most from it. Verify all switches (stereo/mono, clipping eliminator, EQ Bi-Amp/Full Range and level defeat) are set to the mode you want. Turn down the amplifier controls when you power up the system for the first time. Then advance them slowly, one at a time, to verify that each channel is operating correctly. Set input l
