Legendary reverb manufacturer Lexicon (Harman Pro) presented two new products, seen for the first time in Europe. The MX400 and MX400XL are both four-in four-out hardware reverb units for studio and live use. The 1U rack-mounted units have an independent processor on each channel, with the only difference between the units being the connectors on the XL sporting XLRs while the 400 is fitted with quarter-inch TRS jacks. The four inputs and outputs also allow for surround processing and effects are included, making the units an affordable way to enter the surround sound processing arena.
