The Palmer PCABM Passive Cabinet Manager is a small box designed for electric guitarists who wish to use multiple cabinets with one amplifier output. Simply plug one amplifier into either the series or parallel input jack, and plug 1/4' loudspeaker cables into each corresponding cabinet. Please note: Do not use both input jacks at the same time.

You can use this device with 4-,8-, or 16-Ohm cabinets, so long as you properly match the impedance of the amplifier. For your convenience, a chart has been printed onto the top right of the Cab Merger. This will help you calculate the total load of both cabinets. Please make sure that each cabinet you pair with the Cab Merger has the same impedance rating.
