The Wāvtech mini series amplifiers pack an incredible amount of power and features into an extremely small package. Still, with a width of only 4.5”, there are some limitations. That is where the plus series comes in. While still incredibly small at just 5.5” wide, that extra 1” opens up some interesting possibilities. Introducing the link700.4plus The link700.4plus is the most versatile 4-channel amplifier available. Like our mini series multi-channel amplifiers, the plus series models have built-in summing. But with the additional width, we can now accommodate 6-channels of input. That means you can sum a 3-way OEM system and get front and rear full-range output, plus an RCA Pre-Out for a subwoofer amplifier. It is powerful, producing 100 watts x 4 RMS @ 4 ohms, or 175 watts RMS x 4 @ 2 ohms. In BTL mode the power is 350 watts x 2 RMS @ 4 ohms. The link700.4plus has our bassFREQ processor, with 24 dB/octave lowpass and subsonic filters, as well as a fully adjustable 1-band parametric EQ. The optional RLC can be configured to control channels 3/4 when in lowpass mode, or the RCA Pre-Out. link700.4plus Features 700 Watt 4-Channel Amplifier 100 watts x 4 @ 4 ohms 175 watts x 4 @ 2 ohms 350 watts x 2 @ 4 ohms BTL Small Footprint: 10.25”x5.5”x1.65” Variable HP Crossover (-12dB/oct) with 1x/10x CH1/2 Variable HP/BP/LP Crossover (-12dB/oct) CH3/4 Variable LP Crossover (-24dB/oct) RCA Pre-Out Variable Subsonic Filter (-24dB/oct) RCA Pre-Out Adjustable Parametric EQ RCA Pre-Out Remote Level Control (RLC) w/Optional linkRC (Channels 3/4 or RCA Pre-Out) bassFREQ Bass Processor w/Parametic EQ (CH 3/4 or Pre-Out) Active Thermal Management Start/Stop System Compatible Adaptive OEM Load Technology 40V Input Capability Differential Balanced Inputs Variable Gain Adjustment w/Clip LED Auto Turn-On via DC-Offset or Audio Signal Detect Locking Detachable Hi-Level Speaker Terminals Professional Grade Panel Mount RCA’s Compact Aluminum Chassis w/Detachable Mounting tabs
