Description

LAB GRUPPEN C10:4X C Series 4-Channel Amplifier (4x250W)

แอมป์ขยายเสียง LAB GRUPPEN C10:4X, เป็นเพาเวอร์แอมป์แบบ 4 ชาแนล มีกำลังขับ 4×250 วัตต์ per channel at 70 V, 4 ohms, 8 ohms, and 16 ohms, All channels individually selectable for lo-Z or hi-Z Loudspeakers 2 ohm-16 ohm, NomadLink® network ready

The C 10:4X is a versatile four-channel amplifier, delivering 4 × 250 W* at 4 ohms, 8 ohms, 16 ohms or 70 Vrms; 500 W at 100 Vrms is available in bridge mode.

The C 10:4X 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.

This amplifier is 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 2-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 2-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.

Features:

  • Four channels in 2U – Extremely high channel density reduces space requirements and installation time
  • High continuous output power of 250 W per channel at 70 V, 4 ohms, 8 ohms, and 16 ohms*
  • All channels individually selectable for lo-Z or hi-Z Loudspeakers (2 ohm – 16 ohm) and distributed systems can be connected to the same unit
  • Bridged operation – Channel pairs bridgeable for increased output or for driving 100 V systems
  • Patented output stage based on Class D topology
  • High efficiency for lower thermal stress
  • General Purpose Input/Output (GPIO) – Compatible with third-party control systems
  • NomadLink® network ready
  • Universal Power Factor Corrected PSU with IEC inlet
  • Efficient cooling – Dual variable speed, intelligent fans and parallel airflow over output devices provide uniform cooling
  • Comprehensive circuit protection and fault indication
  • Phoenix-style input connectors and barrier strip output connectors

Note:

  • 1: Regarding n.r. (not recommended) notes: The amplifier will be fully operational in bridge-mode into 2 ohm and high impedance (Hi-Z) loads, but due to physical constraints in the construction, the max. output power will not be significantly higher than running individual channels and therefore this mode of operation is not recommended.
  • 2: For sine waves, peak voltage output values translate to Vrms with the formula V/1.41 = Vrms. E.g. 100 V peak equals app. 70 Vrms. Hence, outputs can be set for high-impedance loads without requiring a transformer.
  • 3: Automatic -6 dB gain compensation when bridging channels. Ch.’s A+B and/or C+D, can be bridged individually.
  • 4: PAL can reduce the maximum output power to keep the power supply operating safely, and/or to prevent excessive current draw tripping the mains breaker. Refer to Operation Manual.
