LAB GRUPPEN C 20:8X เครื่องขยายเสียง 8 แชนแนล 2,000 วัตต์

C 20:8X เป็นแอมพลิฟายเออร์ แบบ 8 แชนแนล ให้กำลัง 8 x 250 W 4 โอห์ม, 8 โอห์ม, 16 โอห์ม, 70 Vrms และ 500 W ที่ 100 Vrms เมื่อใช้งานในโหมด Bridge สามารถปรับการใช้งานได้หลากหลาย พลิกแพลงได้หลายรูปแบบ ในแต่ละแชนแนล จะมีตัวจำกัดแรงดันไฟฟ้า เพื่อควบคุมแรงดันไฟฟ้าไม่ให้สูงจนเกินไป (VPL™) ซึ่งจะช่วยให้เอาต์พุตถูกปรับแต่งให้เหมาะสมกับลำโพงได้ทุกตัว ไม่ว่าจะเป็นซับวูฟเฟอร์ขนาดใหญ่ แบบตัวเดียวโดดๆ หรือว่าจะเป็นลำโพงขนาดเล็กแบบเสียงตามสาย 70 V (100V เมื่อใช้งานในโหมด Bridge) โดย VPL จะทำงานร่วมกันกับอินพุตที่ปรับ Gain ได้ ช่วยให้ได้เฮดรูมที่สูงที่สุด โดยไม่จำเป็นต้องคำนึงถึงระดับ อินพุตที่เข้ามา หรือ ความต้านทานเอาต์พุต

The C 20:8X is the most powerful eight-channel amplifier in the C Series family, delivering an impressive 8 × 250 W* at 4 ohms, 8 ohms, 16 ohms or 70 Vrms; 500 W at 100 Vrms is available in bridge mode.

The C 20:8X is one of four C…X models in the C Series, each uniquely suited for a range of installed applications with relatively lower power output requirements. C…X models share most features of the original (higher power) C Series models, and they share the same compact, lightweight 2U chassis. However, the C…X models are offered in both four- and eight-channel versions, offering even greater channel density and installation flexibility. Also, because the unique benefits of Class TD® are more applicable at higher power levels, the C…X models employ a cost-efficient proprietary Class D output design. Other features unique to C…X models include a universal power supply, selectable 35 Hz high-pass filter, and built-in GPIO control facilities.

C 20:8X Series amplifiers are uniquely capable of adapting to a wide variety of demanding load conditions. Each channel has an individually configurable Voltage Peak Limiter (VPL™), which allows the output to be optimized for any loudspeaker load – whether a single large subwoofer or a series of small 70 V loudspeakers (100 V in bridge mode). VPL works in combination with adjustable input gain (adjustable in 4-channel blocks) to achieve maximum headroom regardless of input levels or output impedances. Additionally a 35 Hz high pass filter may be inserted in each 4-channel section.

Every C Series amplifier is ready for the NomadLink® network right out of the box. With NomadLink, key amplifier parameters are displayed via DeviceControl software, and remote control of channel mutes and power on/off is under network control.

GPIO facilities – provided exclusively on C…X models – allow access to key amplifier functions such as power on/off and fault reporting.
