Powerful and Versatile 120-Watt Amplification

The Bose FreeSpace IZA 2120-HZ delivers 120 watts of output power, capable of driving multiple ceiling or surface-mounted loudspeakers in a distributed audio setup. It supports both 70V and 100V high-impedance speaker lines, making it ideal for installations requiring long cable runs and consistent volume across large areas.

Additionally, it can also be used with low-impedance speaker loads (4–8 ohms), providing system designers and installers with the flexibility to accommodate mixed speaker types or retrofit existing installations without needing separate amplifiers.

Built-in DSP with Opti-Voice and Dynamic EQ

One of the IZA 2120-HZ’s standout features is its built-in DSP (Digital Signal Processing), which optimizes sound performance without the need for external processors or complicated programming.

• Opti-Voice® paging technology automatically balances background music and voice signals for clear and intelligible speech during announcements, ensuring seamless transitions without user intervention.

• Dynamic EQ adjusts tonal balance in real-time, enhancing audio clarity and fullness at low or varying volume levels—especially useful in retail or hospitality settings where music may need to stay at moderate levels throughout the day.

These audio enhancements allow for consistent, pleasant sound quality across all zones and throughout all volume ranges.

Easy-to-Install, All-in-One Amplifier Solution

Designed with contractors and integrators in mind, the Bose IZA 2120-HZ simplifies the setup process with features such as:

• Pluggable Euroblock connectors for speaker, input, and remote wiring

• Front-panel controls for master volume, source selection, and mute

• Remote volume and source select capability using the Bose Volume Control with A/B switch (optional)

• Integrated tone control for adjusting bass and treble per application need

Thanks to its compact half-rack width (1RU height), the amplifier can be installed easily in a small equipment rack, under a counter, or inside a cabinet—making it perfect for locations where space is limited but professional audio is essential.

Two-Input Mixer Functionality

The Bose FreeSpace IZA 2120-HZ features an integrated 2-input mixer, enabling simple audio source management for business environments where multiple playback devices or microphones may be in use. It supports:

• Two audio line-level inputs for background music sources (such as media players, music streaming devices, or digital signage systems)

• One balanced mic/line input with phantom power, perfect for paging microphones or local audio reinforcement

Input levels can be configured independently, and source priority can be assigned, making this amplifier an ideal all-in-one audio solution for spaces where background music and paging need to work together effortlessly.

Energy-Efficient Class-D Design

Engineered with energy efficiency in mind, the IZA 2120-HZ utilizes Class-D amplifier technology to reduce power consumption and minimize heat generation. This not only lowers operational costs over time but also allows for quieter operation and longer component life, which is critical for 24/7 commercial installations.

The amplifier features an auto-standby function, which powers down the unit when no signal is detected, then powers it back up instantly when audio resumes—maximizing efficiency without compromising performance.

Seamless Integration with Bose FreeSpace Speakers

The IZA 2120-HZ is engineered to work optimally with Bose FreeSpace loudspeakers, including models like the FreeSpace DS16, DS40, and DS100 series. When paired together, the amplifier automatically applies EQ presets designed to match the loudspeaker’s response curve, eliminating the guesswork and ensuring balanced sound coverage throughout the space.

This plug-and-play compatibility allows for faster installation, reduced system tuning time, and consistent performance across different environments.
