In response to online interest, Mega Audio and UNiKA Pro are proud to announce the EMEA release of the PRO-STP. The Speaker Test unit features a compact stand-alone enclosure and features a Pink Noise Generator which is fitted with a rotary level control, a dedicated XLR output for sending Pink Noise to a mixer or powered speaker, and separate NL4 and NL8 sockets to test impedance and phase of passive speaker drivers directly.
The individual pins on the NL4 and NL8 connectors are accessed by a bank of 4 toggle switches and a momentary Impedance Test push-button sends a 5VDC signal to the selected NL4 or NL8 pins to illuminate green, yellow or red LEDs indicating impedance measurements in the ranges 4, 8 or 16 ohms. The 5VDC button can also be used to aid visual inspection of speaker cone polarity and identifying polarity errors.
The unit requires 4 x 1.5V AA batteries or a third-party 6V external PSU – not supplied. The PRO-STP was designed to a special customer requirement in Asia but has attracted significant interest from European distributors and customers and will be available from the Mega Audio warehouse in Waldlaubersheim, Germany in April 2025.
