INSTALLATION The SP2120 Speaker Protector is designed for standard 19" rack mounting and occupies 1U of rack space. Where possible, avoid mounting the unit directly above power amplifiers or power supplies that radiate significant amounts of heat. If the unit is to be used in a mobile situation, it is strongly recommended that the rear of the unit is supported in the carrying rack to avoid bending the front panel rack mounting ‘ears’.
