English 2.0 Before You Begin Thank you for purchasing a new Bose® commercial power amplifier. It is backed by stateof-the-art engineering and manufacturing techniques to bring you the best in quality craftsmanship and reliable performance. The instructions presented in this installer’s guide are written for professionals who are familiar with the installation and operation of the equipment. If you are not, contact an authorized Bose Professional Products dealer. 2.
3.0 Using The Amplifiers 3.1 Using the Bose Model 2150 commercial power amplifier ® English Once you have installed and wired the amplifier, follow these tips to get the most from it: • Verify that all switches (STEREO/MONO, CLIPPING LIMITER, 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.
English 3.0 Using The Amplifiers 3.4 Thermal considerations When the amplifier is used freestanding, no thermal considerations are necessary other than keeping sufficient ventilation around the unit. Bose® Model 2150 amplifiers may be stacked directly on top of each other without spacer panels. If a Model 2150 amplifier is used with other amplifiers, be sure the heat output from the amplifier does not interfere with the adequate ventilation of the others.

English 4.0 Operation 8. AC Power sequence connector A three-pin Euro style terminal and mating connector are supplied with each amplifier to allow the amplifier to be sequenced on or off remotely. This allows multiple amplifiers to be powered on or off locally by using the first amplifier as the on/off master. These terminals are located on the rear panel of the amplifier and are labeled SEQUENCE. The three terminals are from left to right and labeled ground, SND, and RCV (see Figure 6).
4.0 Operation English 8. AC power sequence connector (cont.) Figure 8 SEQUENCE Connect all the chassis ground terminals together SND RCV 12-15 VDC Supply SEQUENCE SND RCV SEQUENCE SND RCV To remotely begin the sequencing function, close the circuit and supply the DC voltage to the RCV receive pin on the first amplifier. The subsequent amplifiers should turn on at 0.5 second intervals. Note: The front panel power switch should be in the STANDBY position on all of the amplifiers in this group.
4.0 Operation English 8. AC power sequence connector (cont.) When mounting the amplifiers in a common rack, you should verify if the amplifiers’ chassis are sharing a common ground via the rack rails. To do this use a Digital Multi-Meter DMM to measure the DC resistance between the rack rail and the chassis ground of each unit. Set the DMM to measure DC resistance. Connect one probe to the rack rail and the other to the chassis ground terminal on the SEQUENCE terminal of the Bose® 2150.

5.0 Installation English 5.2 Input wiring You can use 1⁄4" phone jacks, XLR connectors, or 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. 5.2.1 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.
5.0 Installation English 5.2.1 Balanced operation (cont.) 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 27). When using the standard input module for either amplifier, you can reverse the polarity of the balanced inputs by changing four jumpers located on the input board, just behind the input connectors.
5.0 Installation English 5.2.2 Unbalanced operation (cont.) For the XLR connector, 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 29). Figure 29 Use Class 2 Wiring For bridged operation. Consult user manual. 1 ⁄4" XLR unbalanced input connection WARNING RISK OF HAZARDOUS ENERGY! MAKE PROPER SPEAKER CONNECTIONS. SEE OPERATING MANUAL BEFORE USING.
5.0 Installation English 5.2.2 Unbalanced operation (cont.) 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 30). Note: The gain remains the same whether the input is balanced or unbalanced. However, if you make an unbalanced connection with a balanced source, there will be a -6dB gain loss.
5.0 Installation English 5.3 Output wiring The Model 2150 speaker outputs on the amplifiers can accommodate wire from 20 gauge up to 12. We recommend that you do not use speaker wire smaller than 20 gauge. You must use Class I (NEC) wiring. 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.
English 5.0 Installation 5.3 Output wiring (cont.) 5.3.3 Stereo/Mono switch This switch selects between NORMAL STEREO (normal stereo), DUAL MONO (dual mono), or BRIDGED MONO (bridged mono) operation. It is located on the motherboard of the input module. For NORMAL STEREO operation, use CH 1 and CH 2 inputs. For DUAL MONO or BRIDGED MONO operation, use CH 2 input only. See the section on bridged operation for more information. Figure 31 Use Class 2 Wiring For bridged operation. Consult user manual.
5.0 Installation 5.3.5 Stereo operation English The STEREO/MONO switch is located behind slot #2 of the standard input module (see Figure 31). For stereo operation move the STEREO/MONO switch to the middle position. Connect your stereo input signal to CH 1 and CH 2 inputs. Note: This is the default setting on the input card. Output wiring: Connect the positive (+) to the desired setting on CH 1 (4Ω, 8Ω, 25V, 35V, 50V, 70V, 100V); then connect the negative (-) to the Common (COM).
5.0 Installation The STEREO/MONO switch is located behind slot #2 of the standard input module (see Figure 31). For bridged mono operation, move the STEREO/MONO switch all the way to the right to the BRIDGED setting. Connect the input signal to CH 2 input (CH 1 input becomes disabled). Outputs: Jumper the Commons (COM) on both CH 1 and CH 2. Next, connect the negative (–) to the desired setting CH 1 output and positive (+) to the same setting on the CH 2 output.
5.0 Installation 5.3.7 Parallel mono English Parallel mono operation is useful when running sustained high levels in a single load or when driving a low impedance load. For instructions, contact Bose® or your authorized Bose Professional Products dealer.
English 6.0 Troubleshooting Troubleshooting Problem No sound, no power (Usually indicates a power supply problem, either in the power line or the amplifier’s power supply.) Power on, low output or no output (Usually signal-source, bad cable or partial output short circuit related.) Cause or Solution • • • • • • • • Check amplifier. Power off, then turn on. Linecord disconnected. Poor fit between the plug and AC receptacle. Try another receptacle. Power off at AC receptacle. Check with tester or lamp.
