The L4Z4 has a very innovative and useful feature. This amplifier is bridgeable from 4 channels to 2 or 3 channels. This will allow you to send more wattage to fewer speakers….let’s say you only want to connect to 2 of the channels. With a total peak power of 4000 watts each channel would then push out 1000 watts. So if you are only using 2 channels you are not getting the full power of this unit! Simple enough! Bridge the 4 channels to 2 channels and you are now utilizing all of the power of this amplifier! The engineers at Technical Pro are consistently creating gear that meets the needs of today’s audio world!

Some additional features include a LED light on the front panel that also holds a clipping feature for each channel. If your source is clipping the amplifier it will alert you immediately helping you maintain a successful sound output. Built in is an advanced cooling system consisting of dual cooling fans. This will keep your gear nice and cool even in a hot or less than perfect environment. The engineers at Technical Pro know that a superior sound AND reliability are the two most important features in an amplifier…and this has them both! This amplifier can stand alone or be connected to a rack or mobile rack by using the rack mountable hardware. It will fit into any 2U rack space. The L4Z4001 from Technical Pro is quickly rising to the top for the number one choice for a professional amplifier and at a cost that is very affordable…if you are serious about your sound you want this!
