This is a hefty (56lbs) six outlet power bank that was previously used in a studio where it provided critical battery backup to their recording equipment in the event of a power outage or power surge. If there was a power outage, the M1500 will continue to power the equipment and thus allowing the user to finish off what needs to be done or provide ample time to do a proper shutdown. The other good thing about this battery powered/ backup power bank is that it produces a true sine wave AC output which is a very clean, low distortion electrical current. This can be very beneficial to sensitive components like CD players or turntables where fluctuating or “dirty” current can distort the quality of the sound. The outlets on the back are also grouped by critical and non-critical components where in the event of a power outage, it would cut off current to the components plugged into the non-critical outlets and reserve its power for the components on the critical outlets.
The unit was previously mounted on a recording rack so there are some scratches and dings around the casing from being pulled in and out from the rack. Otherwise, the unit works perfectly. It is a pretty hefty unit as you can imagine from the big battery pack on board so we will have this securely packed for safe shipping.
