    The Model 2150 amplifier is rated at 150 watts per channel into 4 , 8 , 25V, 35V, 50V, 70V or 100V. In bridged mono operation, it is rated at 300 watts.

  • Page 5: Using The Amplifier

    3.0 Using The Amplifiers 3.1 Using the Bose Model 2150 commercial power ® amplifier 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.

  • Page 6: Thermal Considerations

    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.

  • Page 23: Input Wiring

    5.0 Installation 5.2 Input wiring You can use ⁄ " 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.

  • Page 24: Unbalanced Operation

    5.0 Installation 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.
  • Page 25 5.0 Installation 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.
  • Page 26 5.0 Installation 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).

  • Page 27: Output Wiring

    5.0 Installation 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.

  • Page 28: Stereo/Mono Switch

    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.
