of the real-time spectrum display on the analyzer.
On-screen score display

do have a printer, the SA-3052A provides complete information about the individ-
ual response deviations on a special printout.

SA-3052A automatically times 30 seconds and holds the loudest SPL peak during
the count-down. An LED bar ticks off the seconds for great crowd appeal.

The SA-3052A works directly with your PC-compatible printer. Just plug your
printer into the SA-3052A and you’re ready to go.
SC-10 Soft Carrying Case
The optional soft carrying case protects the SA-3052A from the ravages of porta
ble operation. It includes a large pocket to carry the mike and cables. There is also
a hatch on the bottom of the case to allow access to the power cord connection.
