High Level Inputs High Level Inputs are an added bonus of having the capability of using the source units speaker outputs. Having High Level Inputs is needed if your source unit doesn’t have Low Level Outputs. Tap into the rear decks speakers and you’re all set! Eliminating the need for a Hi to Low Converter. | Low Level Passthrough The NA2000.4 is equipped with RCA PASSTHROUGH. This feature is extremely helpful for multiple reasons. If you desire to add a second amplifier later on the future and don’t have enough RCA Outputs from your source unit. You can use the RCA PASSTHROUGH to get the signals needed to add on. | Nickel Plated Terminal Block Nickel plated terminal blocks have been used on the NEURON series amplifiers. Since most cable is stranded, it is necessary to use terminal blocks to hold the strands together in fastening the connections. This type of terminal block maximizes the connection to deliver the voltage and current draw needed. | Extruded Heat Sink Keeping the amplifier cool increases efficiency to an amplifier. To keep an amplifier cool is a combination of several things, but the most important two are power output and heatsink size. A heatsink size is not the only way to cool down an amplifier. Having increased the area of the heatsink increases the cooling dramatically. So, we extruded the heatsink so we can get the most advantageous area to aid the cooling efficiency. |
