Panasonic – WP-DN700

The WP-DN700 is a digital amplifier with high efficiency and high reliability design.  The 2U size achieves a total output of 2000 W or more in total.  Digital amplifier with high efficiency and high reliability design. 
  • WP-DN 700 is 2 ch power amplifier with maximum output 1000 W × 2 (4 Ω load). 
  • Due to the adoption of class D amplifier circuit and switching power supply, power loss is greatly reduced and space saving is realized. 
  • Equipped with a muting circuit to prevent pop noise when turning on / off the power switch. 
  • Overcurrent protection circuit that prevents overdrive in case of overload · output short circuit, equipped with overtemperature protection circuit to prevent abnormal heating of the power supply circuit · output circuit. 
  • Speaker protection circuit protects the speaker by cutting off the output when the output circuit fails. 
  • Equipped with protect indicator lights, inform the operating status of the protection circuit and system oscillation (when signals exceeding 20 kHz are continuously input). 
  • Corresponds to EIA rack mount. 
  • BTL (Bridged Trans- connect) connection that uses output of 2 ch as output of 1 ch can be used as a power amplifier of 1120 W × 2 (8 Ω load) with WP-DN 360.

Ashly – nXp8002d

The nXp8002d is a 2 channel multi-mode amplifier capable of driving 2 Ohm loads at full power. The maximum rated output power is 800W 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.
