Whirlwind MLTSELAMP Electric Guitar Multiselector Amp 4ch Switching Unit 2 year warranty Made in USA The MultiSelector AMP is a state of the art unidirectional 1-to-4 instrument amp switcher that silently switches one instrument to multiple amps, with complete isolation between amplifiers. The input is electronically buffered with a 1MegOhm input impedance, which emulates a proper amplifier load and prevents any degradation to the instrument?s tone. The signal passes through the MultiSelector AMP transparently, with no coloration and the digitally controlled optical switching is completely silent. Four momentary switches on the front panel turn the channels on and off, with each active output identified by a blue LED. All four outputs of the MultiSelector AMP can be on at the same time. A separate green LED indicates connection of the optional foot controller, the MLTSELAMPR Remote. The rear panel contains the OE? input jack, the four unbalanced OE? output jacks, and a male XLR connector for connecting the optional remote footswitch. The unit is AC powered for ultimate performance and no ?wall wart?. The standard version MLTSELAMP is set for 120 Volt operation. The MLTSELAMPX version is set for 230 Volt 50/60Hz operation. *Multiple amplifier switcher drives up to four amplifiers simultaneously *Single high impedance input provides sonic transparency *Each output is selected independently on the rack or optional remote *Totally silent optical switching *Transformer isolated outputs eliminate ground loops *Polarity switches compensate for wiring or acoustical phase differences *Optional MultiSelector MLTSELAMPR Remote uses XLR mic cable *AC powered for ultimate performance ----------------------------------------------------------------------------------------- Echo tone Music is a long time E-commerce Audio and Musical instrument dealer since 1998.
