8800W 4-Channel Amplifier with NomadLink Network Monitoring and Dedicated Control for Install Applications


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.

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.
