4-Channel 70V/100V Amplifier
แอมพลิไฟเออร์ ให้กำลังไฟสูงสุดอยู่ที่120 วัตต์ 4 ชาแนล แบบ70V-100V ตอบสนองย่านความถี่อยู่ที่ระหว่าง 100Hz-15kHz มาพร้อมกับ ไฟ LED สำหรับแสดงสัญญาณไฟที่ช่วยเพิ่มประสิทธิภาพการทำงานที่เหมาะสม
The DN-470A 4-Channel 70V/100V Amplifier is designed for contractor/install applications, and only for installed speaker systems requiring 70V/100V inputs. This very versatile, one rack space, 120W per channel amplifier has built-in short-circuit protection, and LED indicators for signal present, clipping status and thermal interruption on the front panel. Engineered strictly for the distibution of multiple 70V/100V speaker systems over long cable runs, such as in-ceiling speakers, surface-mount speakers and paging horns.
