LAB GRUPPEN C48:4 C Series 4-Channel Amplifier (4x1200W)

แอมป์ขยายเสียง LAB GRUPPEN C48:4, เป็นเพาเวอร์แอมป์แบบ 4 ชาแนล มีกำลังขับ 4×1200 วัตต์ @ 4 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 48:4 is the third largest amplifier in the C Series family, delivering an impressive 4 × 1200 W at 4 ohms. The exceptional power output plus a long list of protection and monitoring features are all packed into a 2U chassis.

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 a single large 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 under network control.

  • 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.
