Attenuator with relays
Very attractive on the outside the red anodized casing.
It works by adding various resistors in the signal path to get the proper value for the voltage divider.
The resistors are 1% smd metal film but the color marking does not correspond to VIshay. The Omron logo is not visible on the relays.
The first section sounds worse, from step 30 there is an audible change and the response is somewhat better. Audio performance is modest when compared to an Elma A 47 smd for example.
The flat cable connectors do not fit very well and if the mounting is not vertical they can come off when moving the equipment.
The worst thing, without a doubt, is the remote with little range and with random failures, even with new batteries, sometimes you have to press the same command 2 or 3 times to get a response.
In my opinion a bit expensive for what it offers.
Audiophonics customer service as always top notch.
