2.0 Before Y ou 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.
2.1 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 use it. Notify Bose Product Support or your authorized Bose Professional Products dealer.
2.2 The Bose Model 2060 and Model 2150 commercial power amplifiers
The Bose Model 2060 and Model 2150 commercial power amplifiers are specially designed for commercial sound applications. Their rugged construction and low profile allow each amplifier to sustain heavy use with reliability and space-saving economy. Accurate sound and ample power make these amplifiers ideal for critical listening applications.
The Model 2060 is rated at 60 watts per channel into 4, 8, 25V, 35V, 50V, 70V or 100V. In bridged mono operation, it is rated at 120 watts.
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.
Sophisticated protection circuits have been designed into each amplifier to protect your system from unexpected faults. They also help protect each amplifier from excessive temperature, continuous current limiting, and shorted outputs.
The balanced inputs of each amplifier use a high quality, high common-mode rejection differential amplifier for exceptional hum and noise rejection.
In addition, both the Model 2060 and the Model 2150 amplifiers are equipped with an input module to allow for separate equalization of each channel (provided the correct equalization card is installed). Equalization cards (EQ cards) are available for all Bose professional loudspeakers requiring active equalization.

3.0 Using The Amplifiers
3.1 Using the Bose® Model 2060 or 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.
• 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 level contr ols high enough to allow the preceding device to drive the amplifier
to full output. Usually, this is wide open (fully clockwise).
• Write down the settings, either on paper or self-stick dots, and attach to the front of the
amplifier.
• In bi-amplified (multi-amp) systems, start with the low frequency amps turned down or
off. Check each frequency range from highest to lowest to make sure each loudspeaker component is operating correctly.
3.2 General precautions
Caution:
ventilation. Place it away from direct heat sources, such as heating vents and radiators. Make sure the air can circulate freely behind, beside, and above the unit.
Place the unit where it will be protected from heat and allow adequate
3.3 Mechanical considerations
Either amplifier requires two 3.5" (8.9 mm) rack space units with a 16" (40.6 cm) inside depth (including the rear supports). When mounting, 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 from vibration or during transportation.
3.3.1 Rear support
Caution:
chanically support the rear of the amplifier. You can place a shelf across the rear of the amplifier or use brackets in such a way as to support the rear of the unit.
If either unit is rack mounted and the rack is
transported
, you must me-

3.0 Using The Amplifiers
3.4 Thermal considerations
When either amplifier is used freestanding, no thermal considerations are necessary other than keeping sufficient ventilation around the unit.
These amplifiers may be stacked directly on top of each other without spacer panels. If a Bose® Model 2060 or 2150 amplifier is used with other amplifiers, be sure the heat output from each amplifier does not interfere with the adequate ventilation of the others.
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 and a fan from the outside of the rack.
CAUTION:
50˚ C. Be aware of conditions in an enclosed rack that may increase the temperature above room ambient conditions.
Do not allow the chassis to exceed the maximum operating temperature of
3.5 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 the circuit can provide enough current to allow full-power operation 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 during rock music reproduction, with both chan­nels driven into 4 ohms until musical peaks are just below clipping. Under these conditions, the Bose® Model 2060 amplifier requires an average of 3.4 amps for 120V versions (1.9 amps for 220-240V versions). The Bose Model 2150 amplifier requires an average of 4.2 amps for 120V versions (2.2 amps for 220-240V versions).
3.6 Magnetic leakage considerations
You can mount the Bose Model 2060 or Model 2150 amplifier 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.

Level indicators
The level indicators (see Figure 2) for each channel reflect the gain of each output stage. The following LEDs light up when the signal reaches each respective threshold:
CLIP – red light indicates the signal is clipping (0dB)
-6dB – yellow light indicates the signal is at -6dB below clip
-12dB – green light indicates the signal is at -12dB below clip
-20dB – green light indicates the signal is at -20dB below clip
SIGNAL – green light indicates the signal is at -40dB below clip It is common to operate the amplifier so that the CLIP (red) LED illuminates at the loudest
point. If the CLIP LED remains on for an extended length of time or clipping is audible, then the level should be reduced on the channel(s).

In the future a network compatible input card will be available for the amplifiers. When this card is installed, the network LED will flash yellow when the amplifier is receiving network information.
5. Standby Indicator
The LED illuminates yellow when the amplifier is set to STANDBY (standby).
6. Power switch
The power switch has three positions (ON/OFF/STANDBY). When on, the READY indicators illuminate green. When off (middle position), no power reaches the unit and the sequencing function is not active.
When set to STANDBY, the AC mains is connected to the standby circuit. The circuit awaits a 12V DC current to be supplied to the amplifier. When the DC current is detected, a triac allows the AC mains to be connected to the power supply, turning the amplifier on.
Note:
Standby and Sequencing modes are activated at the amplifier only when using the
standard input module.
See Section 4.3.1 for additional information regarding the sequence feature.

Input Modules
1. Standard input module
Through the use of the Bose® input module (the standard module provided with the ampli­fier) and EQ cards, Bose Model 2060 and Model 2150 amplifiers can provide active equal­ization for Bose Model 8, Model 32, Model 32SE, 402®, 502®A, 502B and 802® series II professional loudspeakers.
Each channel of the input module has its own EQ card input connector, which allows independent equalization for each channel. For a view of the input module, refer to Figure 31 on page 28.
2. Input connectors
A combination 1⁄4" TRS/XLR input connector on the input module allows for either a 1⁄4" TRS (Tip-Ring-Sleeve) input or a XLR input. The input module quick-connect terminal block is wired in parallel with the TRS/XLR input connector. This allows for easy connection of stripped wires to the provided connector. Two parallel input connectors allow for simple connection of parallel amplifiers. Only one connection per channel can be used.
Note:
When using the standard input module in mono mode, use CH 2 input only.

3. EQ out connectors
A 1⁄4" TRS output connector provides access to an equalized line level output signal for each channel. If equalizer cards are installed, this signal has passed through the internal equal­izer, but has not passed through the amplifier itself. (For additional information on EQ cards, see Input Modules on page 10.)
This is helpful if several devices are going to be driving similar Bose® loudspeakers (402
®
loudspeakers, for example) with the same source signal. With EQ cards installed in the Model 2060 or Model 2150 amplifier, the EQ OUT (output) of the amplifier can be connected to the line level inputs of additional devices driving the same type of Bose loudspeakers (e.g. 402 loudspeakers). Be sure to use EQ cards that correspond to the type of loudspeak­ers.
4. Equalizer present LEDs
When you install an equalizer card, the corresponding LED illuminates to indicate the presence of the card.
Each channel can utilize a different card. For example, the Bose Model 2150 commercial power amplifier can have both a 402® and a 502®B equalizer card installed. When you install a 502B card in either card position, it automatically selects the high frequency output of the other card. When a system uses two or more amplifiers, and you ar e using a 502B module, use the EQ BI-AMP/FULL RANGE switch to run in the bi-amp mode.
Note:
When EQ cards are installed, the input module recognizes the cards and switches to the equalizer circuitry. If no cards are installed, the input module bypasses the equalizer circuitry and no LED will illuminate.

Engages or bypasses the FX loop. ON (on) allows signals to pass through the FX loop. OFF (off) closes the loop internally.
A four-pin barrier block connector is provided on each channel. The FX loop can be used to send and receive unbalanced signals from outboard signal processing equipment such as EQs, Delays, Limiters, etc. To activate the FX loop, set the dip switch to the ON position.
The send pins (+ and –) are always active and can be used to daisy chain the signal from one amp to another amp via the receiving amplifier’s normal input. The return pins are activated by the FX dip switch.

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 ar e labeled SEQUENCE. The three termi­nals are from left to right and labeled ground, SND, and RCV (see Figure 6).
The sequence feature can be used to turn on or off one or more Bose® amplifiers. When used with more than one amplifier the sequence feature will turn the amplifiers on or off sequentially at about 0.5 second intervals. This will prevent a large turn-on surge through the AC mains supply that could possibly cause disruption of the flow of current through the AC mains.
SEQUENCE
SND RCV
T urning a single amplifier on or off:
Connect the positive side of a 12 to 15 VDC supply to the RCV terminal of the SEQUENCE connector. Connect the ground side of the 12 to 15 VDC supply to the GROUND terminal of the sequence connector.
The amplifier will remain on as long as the DC voltage is present. The amplifier will turn off when the DC voltage is interrupted by opening the circuit at the SEQUENCE connectors. If a switch is used to control the SEQUENCE circuit, it should be a SPST (single pole single throw) type. A control device such as a contact closure contained within a system such as Creston®, AMX® or Panja® can also be used to remotely control the power of the amplifier. The contact closure must be a latching type and not a momentary contact closure.
Figure 6
Sequence connectors
T urning multiple amplifiers on or off:
Starting with the first amplifier in the sequence to be turned on, connect the positive 12 to 15 VDC to the RCV terminal. Next, connect a wire from the SND terminal of the first ampli­fier to the RCV terminal of the next amplifier to be turned on. Continue in this manner until all amplifiers in the sequence are connected.
If the amplifiers are mounted together in a rack where the chassis grounds are connected through common connection via the metal rack rail or by a common AC ground, no other connections should be required (see Figure 7). If this is not the case, simply connect all of the chassis ground terminals together (see Figure 8).

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.
When the DC voltage is interrupted, the amplifiers will then turn off. If there are signal processing and input source devices in the system, they should be turned on before the amplifiers are sequenced on, and these same devices should be powered down after the amplifiers are sequenced off. This will avoid large transient thumps being passed to the loudspeakers attached to the system.
4.0 Operation
Figure 8
Connect all the chassis ground terminals together
When using multiple amplifiers that utilize the SEQUENCE feature of the Bose® 2150, and you would like to power them on, but remote operation is not required, you do not need the DC Voltage to activate the SEQUENCE function. Simply connect the SND send terminal of the first amplifier to the RCV receive terminal of the next amplifier and so on (see Figure 9). The front panel power switch of the first amplifier will activate the SEQUENCE function when switched to the ON position. All other front panel power switches should be in the STANDBY position for the SEQUENCE function to operate properly . Again, if the amplifiers are mounted together in a rack where the chassis grounds are connected together through common connection via the metal rack rail or by a common AC ground, no other connec­tions should be required. If this is not the case, simply connect all of the chassis gr ound terminals together.

4.0 Operation
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 DMM (Digital Multi-Meter) 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. If the DC resis­tance is greater than 0.2 ohms we recommend that you connect the chassis ground termi­nals of the sequence connector together in a daisy chain as in Figure 8. Repeat this for each Bose 2150 in the rack.
You do not have to daisy chain the chassis grounds together if there is less than a 0.2 ohm resistance from the rail to the chassis ground of each unit. Let the rack rail be your chassis ground path.
Using other amplifiers in the power sequence:
The Bose Models 1600 VI and 1800 VI can be used together with the Bose Model 2150 in a sequenced configuration.
However, as the sequence terminal on the Bose ground connector, whenever this manual references the chassis ground connector, you should replace it with some reliable ground connection point on the amplifier chassis, such as a screw that is used in fastening the chassis parts together. A good example would be the screws that retain the Bose input modules to the amplifier chassis. All other connec­tions would be exactly as described in this discussion of sequencing hook-up procedures.
Note:
For operation details regarding the Bose Model 1600 VI and the 1800 VI, please
consult the respective user guides provided with those amplifiers.

9. REMOTE LEVEL (remote level) control
Use a 1k to 10k potentiometer, preferably with a reverse log taper. Identify the terminal of the pot to which the wiper is connected when the knob is set to the fully clockwise posi­tion. Connect this terminal to the RTN (ground return) terminal of the REMOTE LEVEL input plug.
Connect the center terminal of the pot to the CH1 (or CH2) control voltage terminal of the REMOTE LEVEL input plug. The two channels are independently controlled by the voltages applied to the CH1 and CH2 terminals. Both control inputs can be connected together and driven off the wiper of one pot.
Connect the remaining terminal of the pot to the +5V terminal of the REMOTE LEVEL input plug. This connection will set the control voltage to 0 with the knob fully clockwise (maxi­mum level), 5V with the knob fully counterclockwise (minimum level).
Inside the amplifier, a 0V control voltage corresponds to 0dB added attenuation (that is, added to the attenuation already set by the front panel level contr ol for that channel). A 5V control voltage corresponds to 100dB added attenuation. The control voltage effect is “dB linear”: a 2.5V control voltage input will add 50dB of attenuation: the control characteristic is -1dB per 50mV.

REMOTE LEVEL control wiring recommendations
For best results, use 24AWG (or larger) control wiring, especially for the +5V and RTN connections. Since 24AWG wire has DC resistance of 25mW per foot, using 1000 feet of 24AWG (total loop resistance of 50W) to make connection to a 5kW potentiometer will result in a 1% voltage drop. This will cause a reduction in the control voltage range. This voltage drop increases as more current is carried by the +5V and RTN conductors; for example, when the 5V line is used to light a remote LED indicating that the amp is ON.
In the example given above, an additional 10mA load on the +5V and RTN conductors will cause 10% reduction in control voltage range, yielding lower maximum level and higher minimum level. Within reason, conductor capacitance is not a problem since the control voltages are averaged in the amplifier and any additional RC delay will not be noticeable.
Note:
Do not connect the RTN conductor to a ground reference at the remote control location. Ground potential differences will drive currents through the RTN line and cause unpredictable REMOTE LEVEL control performance.

5.3 Output wiring
The Model 2060 and 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. A 14­gauge wire is thicker than 18-gauge wire.
Using the following chart as a guide for low-impedence operation (4, 8):
Wire Length Gauge of Wire
Up to 10' 20 gauge 10' to 15' 18 gauge 15' to 25' 16 gauge 25' to 40' 14 gauge 40' to 60' 12 gauge
5.0 Installation
Use the following as a guide for high-impedence operation (25V, 35V, 50V, 70V, 100V):
Wire Length Gauge of Wire
Up to 250' 18 gauge 250' to 500' 16 gauge
Caution:
within the connector. If even one strand is loose and can touch the adjacent terminal, a short circuit may result.
Be sure all the fine strands of the wire are twisted together and contained
5.3.1 Polarity
In order to have correct phasing between loudspeakers, you must connect them with consistent polarity. While incorrect phasing will do no physical harm, it will diminish your bass response. It is important that each speaker is connected to the amplifier as positive (+) to positive (+) and negative (–) to negative (–).
5.3.2 STEREO/MONO and DUAL/MONO operation
The STEREO/MONO switch is located on the input board behind slot #2 of the standard input module (see Figure 31). For dual-mono operation, move the STEREO/MONO switch all the way to the left to the DUAL/MONO setting. Connect the input signal to CH 2 input (CH 1 input becomes disabled). Connect the speakers to the speaker outputs on the amplifier just as for normal stereo operation. Both speaker outputs will carry the signal connected to the CH 2 input.
Note:
When changing settings, always disconnect the power cord.

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.
Use Class 2 Wiring
For bridged operation. Consult user manual.

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 (4, 8, 25V, 35V, 50V, 70V, 100V),
then connect the negative (-) to the Common (COM). Next, connect the positive (+) to the desired setting on CH 2 (4, 8, 25V, 35V, 50V, 70V, 100V), then connect the negative (-) to the Common (COM).

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.
When connected in this way, each channel “sees” half the impedance of the speaker connected between them.
Note:
Be sure to set both input level controls to exactly the same setting for equal power
distribution per channel.
In high-impedance bridged-mono operation, the amplifier will yield the following results:
Channel 1 Channel 2 Bridged Operation
25V + 25V = 50V 35V + 35V = 70V 50V + 50V = 100V 70V + 70V = 140V 100V + 100V = 200V
