The ART SP4x4 also features ART's "4x4" distribution on the back of the unit -- four of the eight rear outputs are 1.25 inches apart. This allows the user to plug in wide power cables and multiple wall wart devices, and still have eight total power outlets to choose from. Built into the ART SP4x4 is a surge and spike protection system, designed to protect powered equipment from harmful electric surges and spikes.

The unit also has RFI and EMI filtering, a 15 amp breaker, and a total power capacity of 1800 watts. The ART SP4x4 also features a front-located on/off power switch (which lights up when turned on), and a front-mounted circuit breaker reset switch. The rugged, all-steel chassis occupies 1U rack spaces and is intended for installation into standard 19" equipment racks.

Applications for the ART SP4x4 include Live Sound Systems/PA, Permanent or Fixed Installations, Church, Club and Practice PA Systems, DJ Sound Systems, Home and Project Recording Systems, and Monitor Systems.

The ART SP4x4 features a one-year warranty.
