Ashly – nXp4004d
The nXp4004d is a 4 channel multi-mode amplifier capable of driving 2 Ohm loads at full power. The maximum rated output power is 400W per channel at Low Z, 70V, and 100V mode. There is an automatic but defeatable sleep mode consuming <1W, and instant standby mode controlled by contact closure or software. A switch mode power supply auto-detects 120VAC or 240VAC mains, and a Neutrik® powerCON is used for the AC cord. Each channel has selectable output mode of Low Z, 70V, or 100V, an 80Hz high-pass filter, input limiter, and input gain settings of 26dB, 32dB, 38dB, or 1.4V. Each channel has remote DC level control. Input connectors are Neutrik® XLR/TRS combo jack and Euroblock, while output connectors are Neutrik® speakON. The unit has a front panel power switch and level controls that can be disabled. LEDs indicate Protect, Sleep, Disabled, Com, and Bridge mode status, as well as Temperature, Output Current, Output Signal, and Clipping/Mute status per channel.
The unit has Ethernet control with a real-time clock for event scheduling. The unit has serial data remote control, aux preamp outputs, preset control, fault condition logic outputs, optional network audio and AES3 digital audio capability. The unit has 32-bit DSP processing at 48kHz or 96kHz sampling rate. DSP functions include swept load impedance, gain, dynamics including autoleveler and ambient noise compensation, equalization including graphic, parametric, feedback suppressor, and FIR filters, a matrix mixer including automixing, crossover, delay, and a signal generator. The amplifier has temperature dependent variable speed forced-air cooling.

RAM Audio – V9000
RAM Audio® introduces this new generation of professional touring amplifiers based on the field proven QuantaPulse™ Technology: V Series / W Series (with only aesthetic differences).
These new devices feature two or four channel models, ready for rough handling in the touring world. For this purpose, V/W Series amps implement oversized high efficiency regulated power supply with PFC front end to deliver their full performances independently of mains status.
This together with oversized high efficiency audio power stage, forced front to back cooling through a component-free path with removable front panel dust filters, improved rugged mechanical design with even weight distribution, full digital control from LCD display on the front panel… Resulting in: just power, reliability and robustness for your touring gigs!
