4-Channel 300W Power Amplifier
เครื่องขยายเสียง PowerSpace P4300+ เป็นการรวมของพลังงานและ DSP ภายใน 1RU มีค่าการตอบสนองความถี่ 4-8 Ω อยู่ที่ 20 Hz – 20 kHz และส่วนหนึ่งของแพลตฟอร์มที่ครอบคลุมทั้งลำโพง, ตัวควบคุม และโปรแกรมที่ช่วยให้ผู้ใช้งานได้สัมผัสถึงคุณภาพเสียงที่ดี
The Bose PowerSpace P4300+ amplifier combines power and DSP into a 1RU, four-channel design for quick-turn installations. Part of a comprehensive platform of loudspeakers, controls, and software that help installers deliver premium commercial sound systems efficiently, Bose PowerSpace+ amplifiers feature a quick-setup workflow. An onboard configuration utility and intuitive browser-based UI present common tasks in a logical manner, so you can configure the system faster, reducing installation time while increasing setup accuracy. Once installed, Bose-proprietary algorithms offer predictable performance while optional interfaces — such as ControlCenter analog zone controllers — make operation easy for end users. For premium commercial applications, Bose PowerSpace+ models provide amplification and DSP in one integrated, easy-to-configure package.
Features :
- 300 watts per channel and works seamlessly with Bose loudspeakers and controls to create complete commercial sound systems
- Built-in DSP, including SmartBass processing, routing, level control, delays, limiters, Bose loudspeaker EQs, plus input and area EQs
- PowerSpace configuration utility facilitates setup with an integrated webserver and intuitive browser-based UI, including real-time control with signal and thermal monitoring
- Opti-voice paging provides a smooth transition between music and announcements
- Integrated features to simplify commercial installations: Dedicated input for 600-ohm telephone or mic paging, independent 600-ohm music-on-hold and line-level aux outputs, and a NO/NC mute connection
- Load-independent outputs deliver full channel power to either low-impedance loads (4-8 Ω) or high-impedance (70/100V) loads without bridging
- I-Share outputs deliver 2x power level by combining the current of two channels
- Auto-standby mode saves power when audio signal falls below a set threshold, then wakes when audio returns
- Intuitive end-user operation — optional ControlCenter CC-1, CC-2, and CC-3 analog zone controllers provide easy volume control and source selection
Applications :
- Retail stores
- Restaurants and bars
- Hospitality venues
- Conference centers
- Schools
- Auxiliary zones
