The C 10:4X is a versatile 4-channel amplifier, delivering 4 x 250 W* at 4 ohms, 8 ohms, 16 ohms or 70 Vrms (500 W at 100 Vrms is available by bridging two channels) from a 2U chassis.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 PC software, and remote control of channel mutes and power on/off is under network control.
