Versatile Power Amplifier
แอมพลิไฟเออร์รุ่น PowerSpace P4300A ให้กำลังไฟสูงสุดอยู่ที่ 300 วัตต์ต่อช่อง ช่วยปรับปรุงคุณภาพเสียงให้ดียิ่งขึ้นสามารถเชื่อมต่อแบบดิจิตอลได้ ช่องสัญญารอินพุตแบบ Bose Amplink ช่วยให้ช่องสัญญาณเสียงดิจิตอลไม่มีการบีบอัดและเกิดความหน่วงต่ำ
Ideal for zone-expansion applications, Bose PowerSpace amplifiers enhance any premium commercial sound installation with clean, reliable power — and digital connectivity. A Bose AmpLink input allows for multiple channels of uncompressed, low-latency digital audio from Bose DSPs via a single Cat 5 cable. The PowerSpace P4300A provides 300 watts per channel and features versatile outputs that give you the flexibility to deliver full channel power to either low- or high-impedance loads — without bridging — and even send double power to a single zone. For premium commercial applications, Bose PowerSpace amplifiers provide the power and performance to get the job done — pure and simple.
Featues :
-
300 watts per channel and works seamlessly with Bose loudspeakers, DSPs, and controls to create complete commercial sound systems
-
Bose AmpLink input for simplified multichannel digital audio connection to compatible DSPs, reducing terminations and related points of failure
-
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
