J-BOX III Audio Speaker Tester Frequency Response Impedance Measuring Box with Storage Box Support for justMLS REW

J-BOX III Audio Speaker Tester Frequency Response Impedance Measuring Box with Storage Box Support for justMLS REW

Description:
- The J-BOX III Speaker Frequency Response Impedance Measurement Box is a "foolproof" device that measures the frequency response, impedance, TS parameters, harmonic distortion, and other data of speakers and speakers. It integrates the required sound card, speaker amplifier, power amplifier, and sampling circuit for measurement. One knob can switch between sound card calibration (CAL), impedance measurement (Z), and frequency response measurement (SPL). This can simplify the configuration of software and hardware, making measurement very convenient.
- The J-BOX III measurement box can be automatically recognized by operating systems for Windows, MAC, Android, and Linux, and relevant parameters have been specially designed for the sound card, so there is no need to set the volume console of the sound card to use it, truly without adjustment.
- It works in conjunction with software for LspCAD (justMLS) and REW (Room EQ Wizard), please contact our customer service for detailed introduction and operation guidance.
- The J-BOX III has single ended (RCA) and balanced (XLR) microphone input interfaces, and the built-in MIC amplifier provides a gain of +15dB~+30dB to accommodate microphones of different sensitivities. The built-in amplifier can provide three output level adjustments of 1.41, 2.83, and 4.90Vrms (15W). When measuring, the output power and microphone gain can be changed at any time without having to readjust the volume of the computer console. The measurement operation is convenient and simple.

Application:
1. Measure loudspeaker (boxes) (frequency response and impedance)

2. Measure frequency response of active speakers

- The measuring microphone used WM-6X series mic for Panasonic. The microphone comes with a separate calibration file to ensure excellent response characteristics (20-20000Hz, +/-1dB).

- The bottom of the microphone attachment is specially made with a 1/4 thread camera mounting hole, which can be easily mounted on a regular camera tripod.
