Audiofanzine FR's review

Electro-Harmonix Stereo Polyphase XO
(Originally written by solo84/translated from Audiofanzine FR)
Analog phaser

One mono input, one stereo output

Lots of settings (waveform, envelope, feedback, LFO, start and stop points, speed, etc.)

It works only with a 24-volt PSU (included, no battery operation)

It's a pity that the unit doesn't have a stereo input! It would make it a must-have!!! I give it a 9 because of this last point.

UTILIZATION

The unit requires some learning time and I'm only getting to know it. The user's manual is ridiculous and the settings aren't intuitive. But it's only a phaser so you'll surely find out how it works! I will update this review later...

SOUND QUALITY

With a simple setting for arpeggios (Pink Floyd 70's sound) the result is very interesting, not as extreme as a Phase 90, quite organic and much more subtle. It reminds me of the Small Stone... The device doesn't alter the original signal and the stereo imaging is wonderful.

Everything is possible, even extreme effects! It's a convenient phasing effect unit! The phase start and stop controls and the feedback setting provide huge sound possibilities! You can also use an envelope instead of the LFO, etc.

I haven't tested it within a mix yet even though it's the most important thing! So I will update this review later...

OVERALL OPINION

Pros:

- Very nice sound

- Unaltered source signal

- Huge editing possibilities

- Look and construction

Cons:

- Not easy to use

- Ridiculous user's manual.

Electro-Harmonix Stereo Polyphase XO
There is a (poly) phaser analog stereo output with a switchable for a LFO envelope follower. Not in stereo (but not serious) and a speed selector applicable to the envelope or LFO. All encased in a metal housing typical of the brand.
The unit is supplied with 24 volts via a power supply. No battery.

UTILIZATION

Configuration simple: one connects, triturated, we are happy (or not). Editing is, like most pedals directly on the interface (very nice, by the way).

SOUND QUALITY

Really top quality sound, the effects of polyphase allows very subtle or very pronounced. It works on many sound material (guitars, keyboards, synth, drum machine). We appreciate the scale setting the phaser action via "start" (defined frequency point of entry into action of phaser) and "stop" (defined by the exit point), very convincing and making the pedal very versatile. Switch the LFO / ENV is a great idea, it manages to make the material sound very liquid and organic foot.

OVERALL OPINION

I use it for 4 months. yes, I qq phaser pedal or in multi eff, but this one is unique. I like the pedal in its entirety and nothing that displeases me. This phaser is clearly the best I've tried.
