Description

LAB GRUPPEN C88:4 C Series 4-Channel Amplifier (4x2200W)

แอมป์ขยายเสียง LAB GRUPPEN C88:4, เป็นเพาเวอร์แอมป์แบบ 4 ชาแนล มีกำลังขับ 4×2200 วัตต์ @ 2 Ohms, Lo-Z or Hi-Z (70 V / 100 V) – Selectable per channel, normal or bridged, Class TD® amplifier topology, Screw terminal output connectors

The C 88:4 is the new flagship of the C Series and is the most powerful single frame, 4-channel installation amplifier ever built! Delivering an amazing 4 × 2200 W at 2 ohms, this amplifier is powerful enough for the most demanding of installed sound applications including, larger sub-woofers, large array systems and broader multi-power-level/impedance applications. Packaged in a compact 2U chassis, the C 88:4 sets a new benchmark for extreme power and flexibility in an installation-dedicated amplifier.

C 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 one massive subwoofer or a series of small 100/70 V loudspeakers. VPL works in combination with adjustable input gain to achieve maximum headroom regardless of input levels or output impedances.

Every C Series 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 managed efficiently under network control.

Features:

  • Unprecedented power density – Total output of 8800 W (2 ohms) in 2U
  • Four channels – All channels bridgeable for 2- or 3-channel configurations
  • Lo-Z or Hi-Z (70 V / 100 V) – Selectable per channel, normal or bridged
  • Patented Class TD® amplifier topology
  • Voltage Peak Limiter (VPL) – Configurable per channel to optimize each output for connected loads
  • Phoenix-type input connectors
  • Screw terminal output connectors
  • Comprehensive protection and warning – Excessive output current, DC, high temperature, very high frequency (VHF), short circuit, open load, mains fuse protection, and soft start
  • Efficient and uniform Intercooler® cooling
  • NomadLink® network ready

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: Separate 230 V or 115 V versions available. Not selectable on the amplifier.
  • 5: 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.
