The link300.4mini is in a class by itself. The most obvious thing is its extremely small size, but don’t Iet that fool you. Unlike most small footprint amplifiers, the link300.4mini is bridgeable. It can easily drive a nice set of components as well as a subwoofer. The link300.4mini has Wāvtech’s best in class LOC, with built-in loading and the ability to handle up to 40V of hi-level input. Perhaps the most unique feature is the built-in summing. For factory audio systems that don’t have a full range signal, the link300.4mini can handle that internally, so no additional processor is required. The level trim adjustment allows for fine tuning the output of each pair of channels. As if all of that isn’t enough, the link300.4mini is compatible with OEM start/stop systems as well. link300.4mini Features 300 Watt 4-Channel Amplifier 50 watts x 4 @ 4 ohms 75 watts x 4 @ 2 ohms 150 watts x 2 @ 4 ohms BTL Small Footprint Only 6.4”x4.5”x1.65” Variable Hi/Low Pass Crossover (-12dB/oct) Built-In Summing w/Level Trim Adjustment Start/Stop Sytem Compatible Differential Balanced Inputs Variable Gain Adjustment w/Clip LED Auto Turn-On via DC-Offset or Audio Signal Detect Adaptive OEM Load Technology Locking Detachable Hi-Level Speaker Terminals Professional Grade Panel Mount RCA’s Compact Aluminum Chassis w/Detachable Mounting tabs link300.4mini Specifications Input Sensitivity SPK: 1-20Vrms, 2-40Vrms RCA: 0.2V-5Vrms, 0.4V-10Vrms Max Input Voltage (SPK): 40Vrms Frequency Response: 45kHz (+0/-3dB) THD+N: 80dBA (1W, 4Ω)
