FreeSpace IZA 2120-HZ integrated zone amplifier

   FreeSpace IZA 2120-HZ แอมป์โซนแบบผสมในตัว (Integrated Zone Amplifier) ออกแบบมาเพื่อยกระดับประสบการณ์เสียงในระบบ เพลงพื้นหลัง/พื้นหน้า และระบบประกาศเสียง (Paging) โดยเฉพาะเมื่อใช้งานร่วมกับลำโพง FreeSpace SeriesIZA 2120-HZ เหมาะสำหรับการใช้งานในเชิงพาณิชย์โดยตรง มาพร้อมฟีเจอร์สำคัญ ได้แก่:

• Loudspeaker EQ ที่เลือกได้ เพื่อปรับจูนเสียงให้เข้ากับลำโพงและเพิ่มคุณภาพเสียงโดยรวม
• Opti-Voice® Paging เพิ่มความคมชัดในการประกาศเสียงพูด พร้อมการเปลี่ยนโหมดที่ราบรื่น
• Dynamic EQ ที่ช่วยให้เสียงดนตรีมีความเต็มอิ่มและสมดุลในทุกระดับความดัง

 

FEATURES

• True two-zone capability provides two independent outputs that each support volume/source selection remotes, EQ, tone controls, and paging/auxiliary routing options
• Opti-Voice paging equalizes the vocal frequency range for clear speech intelligibility while providing seamless transitions
• Dynamic EQ ensures full and balanced music at any volume level
  
• Independent Loudspeaker EQ per output enriches audio quality and simplifies connection to Bose Professional loudspeakers: FreeSpace 3 systems, FS3 subwoofer, FS2, FS4 and DesignMax DM2
• Dual remotes support optional volume/source selection for independent, or combined, zone control which eliminates the need for bulky, inefficient, and sound-altering 70/100V in-line volume controls
  
• Reliable 2 × 120 W Class-D amplification optimized for 70/100V high-impedance applications
• Intuitive feature setup enables the amplifier to be configured without a PC for remote, paging, auxiliary input/output and automatic standby options
• Auto-Standby feature allows the amplifier to consume less power when not in use
• Simplified front panel interface provides end users with tone, source selection and master volume controls as well as a connection to mobile sources via a 3.5 mm connector
• Remote muting allows the amplifier to be muted via a centralized control system
