The C 5:4X is a versatile four-channel amplifier, delivering 4 125 W* at 4 ohms, 8 ohms, 16 ohms or 70 Vrms; 250 W at 100 Vrms is available in bridge mode.
The C 5:4X is one of four CX models in the C Series, each uniquely suited for a range of installed applications with relatively lower power output requirements. CX models share most features of the original (higher power) C Series models, and they share the same compact, lightweight 2U chassis. However, the CX models are offered in both four- and eight-channel versions, offering even greater channel density and installation flexibility. Also, because the unique benefits of Class TD are more applicable at higher power levels, the CX models employ a cost-efficient proprietary Class D output design. Other features unique to CX models include a universal Power Supply, selectable 35 Hz high-pass filter, and built-in GPIO control facilities.
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 software, and Remote Control of channel mutes and power on/off is under network control.
GPIO facilities provided exclusively on CX models allow access to key amplifier functions such as power on/off and fault reporting.
* Maximum continuous output power, all 8 channels driven, VPL set at 100 V and Gain set at 32 dB.
