## Customer Reviews

### ⭐⭐⭐⭐⭐ Zero noise!
*by  on Reviewed in Canada 6 April 2024*

I've heard that a few people have had unwanted noise issues with this unit.Personally I've had no noise problems at all. That said I put a ferrite choke on the ground approximately 3" from the dsp and I'm using audioquest tower rca's 2'. So far I'm very impressed with this dsp! The software for windows is a breeze to set up. Atm I'm using it with Focal access 2way passive and in the near future will be running 3way active again with the Focal 165AS 3.

### ⭐⭐⭐⭐⭐ Fijne DSP
*by  on Reviewed in the Netherlands 13 March 2026*

Ik gebruik deze DSP voor een 3 weg aktief open baffle luidsprekersysteem voor in huis.Het configureren is erg simpel als je al wat thuis bent in het werken met filters.Het ruisprobleem waar ik hier en daar iets over lees valt in de praktijk erg mee.Ik heb 3 x de fosi ZA3 waarvan ik de volumeknop iets terugdraai om de ruis uit de DSP te verminderen, en heb er nu geen last meer van.Het valt op als je luidsprekers een hoog rendement hebben.Verder wil ik wel waarschuwen omdat Amazon,de verkeerde adapter voor de europese markt erbij doet, de ingangsspanning van 240V is prima maar het is de amerikaanse uitvoering dus die met platte kontakten !!!!! Ik heb daar melding over gemaakt,maar dat wordt niet begrepen.Ik heb alles teruggestuurd en kreeg 2 dagen later een andere DSP met…..weer dezelfde verkeerde adapter.Gelukkig had ik zelf nog een adapter liggen van 12V.De bijgeleverde adapter is 12V 1,5 A.Omdat ik graag de bijgeleverde adapter wil gebruiken,heb ik nu een US naar EU adapter besteld.Voor de DSP geef ik 5 sterren, zeker gezien de prijs, dit ook voor de service van Amazon,maar helaas heeft het niets geholpen !!! Ik heb mijn best gedaan door een mailje te sturen van het probleem.Veel succes als je hem ook besteld,bekijk eerst de adapter, het terugsturen is zinloos !!!Koop de US-EU omzetter……
