Zapco Class A/B Digital Processing AmplifiersThe Zapco Digital Processing amplifiers and the Zapco stand alone processor are back. Same great sound, same clean Zapco power, same stealth fighter looks. What's changed? We've added a boatload of fresh processing power and improved the control program. The new DPN is easier to load and use and the hassles of loading drivers are gone. Just drop the new system onto your desktop and go.And here's what you'll find: * First, the new DC series takes speaker level inputs as well and preamp inputs, so hooking up to a factory system is now a breeze. Not only that, but it will sum the channels as well if need be.* Of course the amps have a full DSP on each channel. And on the Stand-alone DSP-Z8 we have added 2 more channels so you can run an active 3-way system and still have a subwoofer output.* The crossover now runs from a shallow 6dB/Octave to a steep 36dB/Octave* Signal delay resolution has been increased so you can now adjust down to under 3mm* Phase can now be adjusted in 45 degree steps* Muting, either by single channel or by channel pairs lets you hear one channel at a time * VSE Voltage Sensitive Equalization is a fully parametric EQ band that can be set to engage at a preset signal voltage. This is great for factory integration. If your car changes the system response at a given volume you can set the VSE band to counteract the factory and keep your flat responses just like you tuned it.Like we said, a boatload of improvements. But there is one thing that hasn't changed...The Price! That's right, with all these improvements, the DC line remains a great value with most of the models right at the same price as last year's models. Some are even less than last year.Max RMS Power 360 Watts @ < 0.05%THD 4 channel; DC Full range class A/BPower @ 2Ω: 4 x 90 wattsPower @ 4Ω: 2 x 180 wattsBridged, 2 ohms: 2 x 180 WattsRMS Rated Power @ < 0.05%THDPower @ 2Ω: 4 x 90 wattsPower @ 4Ω: 2 x 100 wattsBridged @ 4Ω: 2 x 180 wattsMore about Zapco Power-On-Board, Full Function DSP-Intelligent Rail Voltage Control-USB Input for PC Control-2nd Generation Digital Programming Network-Heavy-Duty, High-Current, Insulated Terminal Blocks-Space Saving Flush Wiring Connections-Bridgeable-Three-Channel Capable-Gate Drive Boost Circuit-High-Current Bipolar Outputs-Optically Isolated MOSFET Power Supply-Three year warranty (If Authorized Dealer Installed)-Quality Zapco construction-Dimensions in Inches : 7.12(W) x 2.35(H) x 19.40(L)The DC364 gives you 4 channels of DSP control with 50 watts RMS/Channel at 4 ohms and 90 watts RMS/channel at 2 ohms.
