Responding to online interest, Mega Audio and UNiKA Pro have announced the EMEA release of the PRO-STP, a Speaker Test unit in a compact stand-alone enclosure and featuring a Pink Noise Generator and separate NL4 and NL8 sockets to test the impedance and phase of passive loudspeaker drivers directly.
The noise generator uses a rotary level control and is accompanied by a dedicated XLR output for sending pink noise to a mixer or powered loudspeaker.
The individual pins on the NL4 and NL8 connectors are accessed by four toggle switches and a momentary Impedance Test pushbutton that sends 5V DC to the selected pins to illuminate green, yellow or red LEDs indicating impedance in the ranges 4Ω, 8Ω or 16Ω. The 5V DC button can also be used to aid visual inspection of loudspeaker cone polarity and identify polarity errors.
The unit requires four 1.5V AA batteries or a third-party 6V PSU.
The PRO-STP was originally 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 Q2 2025.
