Bose Professional AudioPack Pro S4 Black – Background Music and Paging System 120V NA

Product Overview

The Bose Professional AudioPack Pro S4B is a complete, pre-matched background music and paging system designed for small commercial spaces that require a straightforward, professional audio installation without the complexity of specifying individual components. The system bundles a FreeSpace IZA 190-HZ integrated zone amplifier with FreeSpace FS2SE surface-mount loudspeakers — all factory-matched and tuned for consistent tonality, clear voice reproduction for paging, and smooth broadband response for background music. With 145-degree horizontal and 140-degree vertical coverage from each loudspeaker and a calculated maximum SPL of 99 dB at 1 meter, the AudioPack Pro S4B is appropriate for conference rooms, retail spaces, offices, training rooms, and other commercial meeting environments up to modest square footage. The amplifier and loudspeakers ship in a single box with QR-code access to a step-by-step online installation guide, reducing installation time and the need for specialized AV configuration expertise.

Product Description

The AudioPack Pro S4B system centers on the FreeSpace IZA 190-HZ integrated zone amplifier, a half-rack-wide, 1RU unit that combines amplification, mixing, and DSP into a single self-contained module. Front-panel controls include a power switch, input selection switch, treble knob, bass knob, mic/line gain knob, and master level knob — all the adjustments a facility manager or non-technical user needs to operate the system day-to-day without accessing software.

The rear panel provides DIP switch control for amplifier mode, a loudspeaker EQ preset selector (optimized presets for FreeSpace FS2C, FS2P, FS2SE, FS4CE, and FS4SE), individual input gain trims (A/B/Page mic), and an output trim. The integrated DSP runs at 48 kHz/24-bit with 10.4 ms analog-to-analog latency and includes Opti-Voice EQ for paging clarity and Dynamic EQ for low-end compensation at lower listening levels. The amplifier supports 70V and 100V distributed audio operation via transformer taps (1, 2, 4, 8, 16W, and transformer bypass) on each loudspeaker, or 16 Ω nominal in bypass mode.

The FreeSpace FS loudspeakers are rated IP55 for moisture and dust resistance, manufactured with highly UV fade-resistant engineered plastic housings and perforated steel grilles with a tamper-resistant design. The Bose logo is removable for a clean, unbranded appearance in upscale commercial environments. Each loudspeaker handles 16W continuous and 64W peak power, with a frequency range of 83–19,000 Hz (-10 dB) and 87 dB sensitivity at 1W/1m. The system is available in black (this listing, SKU 888478-1110) and is rated for operating temperatures from -25 °C to 70 °C, making it appropriate for installations where temperature control is not guaranteed. Power consumption is 15W idle and 200W maximum; mains input is 100–240 VAC (±10%), 50/60 Hz. Backed by a 5-year Bose Professional warranty.

Frequently Asked Questions

What is included in the AudioPack Pro S4B box?
The S4B system ships as a complete package including the FreeSpace IZA 190-HZ integrated zone amplifier and the matching FreeSpace FS2SE surface-mount loudspeakers (in the quantity corresponding to this system tier). All components are pre-matched by Bose Professional. A QR code on the box links to the step-by-step online installation guide.

Is any software configuration required to operate the AudioPack Pro S4B?
No software is required for basic operation. The IZA 190-HZ amplifier has all essential controls on the front panel (input selection, tone, level, mic gain) and the loudspeaker EQ preset selector on the rear panel. No PC, app, or network connection is needed. This makes the S4B appropriate for locations where ongoing IT involvement is not practical.

Can the AudioPack Pro S4B handle paging alongside background music?
Yes. The amplifier includes a dedicated mic/line input with separate gain control and an Opti-Voice EQ preset that applies frequency shaping optimized for voice intelligibility over background music. This allows a paging microphone to be connected directly to the amplifier for simultaneous operation with a music source.

Does the system support 70V or 100V distributed audio for additional loudspeaker runs?
Yes. Each FreeSpace FS2SE loudspeaker includes a transformer with taps at 1, 2, 4, 8, and 16W (70V) and 2, 4, 8, and 16W (100V), as well as a bypass position for direct low-impedance (16 Ω) connection. The IZA 190-HZ amplifier supports both distributed and low-impedance modes, selectable via the rear-panel DIP switch.

Can additional loudspeakers be added to the system beyond what is in the box?
Yes. Additional FreeSpace FS2SE surface-mount loudspeakers are available as optional accessories. The FreeSpace IZA 190-HZ amplifier supports expanded loudspeaker configurations. Bose Professional's step-by-step guide and technical support resources are available to assist with system expansion planning. Creation Networks can provide pre-sales design assistance at creationnetworks.net.

Are the loudspeakers suitable for outdoor or semi-outdoor installations?
The FreeSpace FS loudspeakers carry an IP55 ingress protection rating (dust and water jet resistant) and are rated for operating temperatures from -25 °C to 70 °C. They are suitable for covered outdoor areas such as patios, covered walkways, and semi-exposed commercial entrances, though direct rain exposure should be avoided.

What is the warranty on the AudioPack Pro S4B?
The AudioPack Pro S4B carries a 5-year Bose Professional manufacturer's warranty covering both the amplifier and loudspeakers. Creation Networks provides warranty support coordination. Contact us at creationnetworks.net for assistance.
