The C 5:4X is a versatile 4-channel amplifier, delivering 4 x 125 W* at 4 ohms, 8 ohms, 16 ohms or 70 Vrms (250 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. Maximum continuous output power, all 8 channels driven, VPL set at 100 V and Gain set at 32 dB.
