TEST: Phonic PAA3X

 It roars, it whistles, it scratches. Whether in the studio, live or with the home surround sound system, you always and everywhere fight against overemphasis, frequency holes and phase problems. Even a trained ear sometimes has to capitulate to the complexity of the frequencies, which ultimately always calls for an analyzer. With the Phonic PAA3X, the Taiwanese manufacturer has a handheld version on the market that can display far more than just frequencies.

The features of the Phonic PAA3X

With the dimensions (H x W x D) 156 mm x 90 mm x 37.5 mm, the Phonic PAA3X is very handy, similar to a hand-held TV from the eighties, with the weight of just over 300 grams after a few minutes can already pull a little on the biceps. Ultimately, the weight and dimensions are really appropriate for the range of services offered.

First, let's look at the Phonic PAA3X's accessories. The product is delivered in a padded synthetic leather bag, which can also be attached to a belt if required. With the supplied 5V power supply, not only the internal battery of the product, but also an iPad / iPhone etc. can be charged due to the 2A output power. A corresponding USB cable is of course also included.

The measuring antenna of the Phonic PAA3X is conveniently parked in an antenna slot inside the housing. It's a bit of fiddling to get them out of there, but the level of detail is still excellent. In order to be able to attach them to a microphone stand, if necessary, a corresponding screw mount and mini-XLR extension cable are also included. On the back of the housing there is also a tripod mount for the analyzer itself. Finally, there is a micro SD card on which display snapshots can be saved for further analysis.

On the underside of the housing there is an XLR input and output for feeding in external sources as a signal source and for outputting the signal from the internal noise generator in the form of sine, sweep, polarity control and, of course, pink noise. For navigating within the menu, four pushbuttons were positioned on the front of the housing, which, in addition to the usual up / down / left / right, also trigger the snapshot of the display. The main navigator, on the other hand, is a rather wobbly wheel with a push function on the left side of the case. In terms of haptics, it is more reminiscent of a volume control on a toy, it could indeed have been made more valuable.

The features of the Phonic PAA3X

The Phonic PAA3X has set itself the goal of displaying the most important acoustic problems as simply and easily as possible. It does not offer a solution in the form of automatic calibration or anything similar. Should e.g. If, for example, the frequency response of a product needs to be corrected, a corresponding external tool in the form of an EQ or similar must also be available.

Well then, what can the Phonic PAA3X do?

1.) Real Time Analyzers

Basically self-explanatory for anyone who has dealt with the subject. The dB range is flexible, so that you can measure up to 130 dB at very low as well as at high volumes. Nothing extraordinary if it weren't for the EQ Setting function. A very nice feature where the analyzer shows which frequency is over-present and which under-present with a 0 dB line placed in the middle by means of a corresponding line up and down. Ideally, a flat line would appear here.

2.) Reverberation measurement

The eternal fight of the FOH against the room acoustics. This RT 60 algorithm measures the time it takes for a signal to drop 60Db. This can be done without filtering (linear weighting) or with an applied filter.

3.) Level meter

Also self-explanatory, if you belong to the pitiful species of the "Noise Police" at the music fairs or the like. A MAX and an RMS display provide information about the current level. The specification can be in dBu, dbV or Voltage.

4.) Polarity

You wouldn't believe how often, even with high-end components, the polarity of the loudspeakers used was simply not set up correctly. This can be checked very quickly by outputting a test tone.

The Phonic PAA3X in action

Of course, most see the application area of the Phonic PAA3X in live sound reinforcement or for the purpose of optimizing monitoring in a control room. Errors can be found quickly, but fixing them can mean a lot more than simply tweaking the 31-band EQ. Unfortunately, spatial misdesigns or unfavorable reflections cannot be solved from the start, but at least you know very quickly where the problem comes from using the Phonic PAA3X.

However, people tend to forget that a mobile analyzer can provide very good service in the rehearsal room, in the home hi-fi system or even inside a car. How often does the bass boom in the rehearsal room for all other instruments up to the stand-up collar, whereby a different positioning of the box or a skilful operation of the graphic EQ means a relief for the colleagues.

Anyone who wants to optimize their vehicle will also be happy with the Phonic PAA3X, provided they are not of the monkey-maker species who make every traffic light stop torture with their bass-heavy Eurobeat droning.

Rarely have I been able to complete an all-round acoustic analysis in such a short time, and without changing the device. A kind of acoustic Swiss army knife. We recommend.

Conclusion

With the Phonic PAA3X, there is a handheld analyzer on the market that lists all the important points in terms of signal flow in no time at all. A clear, self-explanatory menu navigation and some very nice detailed solutions leave a very good impression.
