  • Page 2: Safety Information

    THE PURPOSE OF SERVICING THE IDENTIFIED BOSE PRODUCT BY AN AUTHORIZED BOSE SERVICE CENTER OR OWNER OF THE BOSE PRODUCT, AND SHALL NOT BE REPRODUCED OR USED FOR ANY OTHER PURPOSE. WARRANTY The Bose PackLite Model A1 Amplifier is covered by a limited 1-year transferable warranty.

  • Page 3: Product Description

    Product Description The PackLite Model A1 power amplifier is a small, lightweight, powerful, and easy-to-use amplifier that interfaces quickly with the Bose PS1 power stand and B1 bass modules to ® provide high bass output for demanding instruments such as bass guitar and drums. The con- nections are quick and easy: plug in the AC cord, connect the A1 to the PS1 power stand, and play.

  • Page 4: Amplifier Rear Panel Connections And Controls

    Amplifier Rear Panel Connections and Controls 1 - AC power connector: Accommodates the supplied AC power cord to connect your amplifier to the appropriate AC (mains) outlet. Check the product label of your amplifier for the voltage rating: 120V or 220-240V. 2 - Power switch: In the ON (l) position, applies power to your amplifier.

  • Page 5: Setting Up A Single A1 Amplifier

    Setting Up a Single A1 Amplifier The A1 amplifier is designed to add more bass output to a system that already has two B1 bass modules connected to the Amp 3 OUT connector on the PS1 power stand. The A1 amplifier can power up to two additional B1 bass modules.

  • Page 6: Using Multiple A1 Amplifiers

    Using Multiple A1 Amplifiers To add more bass capability to your system, you can connect multiple A1 amplifiers as shown below. 1. Connect the AC power cord to an AC (mains) outlet. 2. Make sure the Power switch is OFF. 3.

  • Page 7: Using The A1 In Other Applications

    Using the A1 in other applications The A1 amplifier can be used as a power amplifier in other system configurations. The A1 can drive other passive loudspeakers including subwoofers, floor monitors, studio monitors, and guitar cabinets. The A1 can amplify a balanced or unbalanced signal from a line- level device, such as a mixing console, and drive any loudspeaker load (4-ohm minimum) that is capable of handling 250W.

  • Page 8: Specifications

    Specifications Electrical Power, 4-ohm load: 250 watts RMS (1 kHz, 0.1% THD) Power, 8-ohm load: 125 watts RMS (1 kHz, 0.1% THD) Minimum loudspeaker load: 4 Ohms Signal to noise: 100 dB (20 Hz to 20 kHz) Voltage gain: 30 dB Input sensitivity: 1.15 V (+3.4 dBu) Input sensing:...

  • Page 9: Production Notes

    PRODUCTION NOTES The PackLite A1 amplifier has been manufactured in two versions, a 120V version (product code 039057) and a 220-240V version (product code 039058). The early 120V units, serial numbers 039057Z52620201AC to 039057Z52621200AC, are non- RoHS compliant units. 120V units built after the 5262 Julian date (9/19/2005) are fully RoHS compliant.

  • Page 43: Theory Of Operation, Packlite Model A1 Amplifier

    THEORY OF OPERATION PackLite™ Model A1 Amplifier 1. General Overview The Personalized Amplification System™ family of products currently consists of the PS1 power stand, the L1 Cylindrical Radiator loudspeaker and the B1 bass module. The PS1 power stand ® can power up to two B1 bass modules. This is sufficient for most instruments with the exception of some applications of bass guitar, drums (kick drum) and some types of recorded music playback.
  • Page 44 THEORY OF OPERATION AC Power Input Filter Section (continued) D100 [B/C3] rectifies the AC signal, which is filtered by C107 [C4] and C108 [B4]. N100 [C3] and N101 [B3] provide in-rush current protection when connected to the AC line. MOV1 [C4] and MOV2 [B4] are for surge protection. SG101 through 104 [B/C2] provide an ESD discharge path to the AC mains around the higher impedance of the coils.
  • Page 45 THEORY OF OPERATION Amplifier Section (continued) IC4A and IC4B [D2] provide buffers for the audio input, and provide the ability to accept bal- anced or unbalanced inputs. The PackLite A1 amplifier uses the inputs in an unbalanced configuration. R21, R24, R25, R26 [A/B3] provide resistive dividers to determine the under and over-voltage protection thresholds.
  • Page 46 THEORY OF OPERATION 6. Input/Limiter PCB Assembly Note: Refer to the Input/Limiter PCB Schematic Diagram, sheet 1 of 1 for the following. The information inside the brackets [ ] is the schematic grid location on the sheet. The Input/Limiter PCB assembly provides: •...
  • Page 47 We require 24 dB of gain in that case. If a user connects to a PS1 using an unbalanced cable, they will lose 6 dB of signal going into the PackLite A1. In that case, U304 [C2] will detect that RING is connected to SHIELD, which is grounded, and, after a few seconds, will increase the gain of U301A [D4] by 6 dB in order to compensate.
  • Page 48 THEORY OF OPERATION DC Offsets Because of the DC offsets involved (the RING of the input jack is connected to a DC voltage and will momentarily shift when a plug is inserted into the jack), there can be a clicking sound output from the amp when plugs are inserted or removed from the input jacks, as well as when the gain changes.
  • Page 49 THEORY OF OPERATION Fan Control The fan turns on when the signal level is high, rather than using a thermal detector. When the input signal reaches about -10 dBV, the Q305/Q310 [B2] combination will turn on the fan. LED Control The green signal LED will turn on at an input level of about -26 dBV.
