Passion IA350A

Posted · Add Comment

Passion integrated amplifiers have been award winners over the years and we feel sure that this latest model is guaranteed the same success.

Staying with the uncluttered style synonymous with YBA, the front panel has simply an input and volume selector. The turn on switch is cleverly concealed beneath the front left hand side of the amplifier.

The source selector toggles between many different inputs -both analog and digital. The digital inputs include an S/PDIF (75  Ohm) COAXIAL digital input, a USB (24/192KHz) plus AES/EBU, I2S, and iPod, all of which  receive digital signals from separate digital components.  The analog inputs include 2 RCA and 1 Balanced.  All digital inputs automatically adjust to any of the standard digital-audio data-rates from 16/44.1Khz to 24/192Khz.

It is possible to switch the digital section off completely if your wish is to listen at times to purely analog.

The Passion IA350 also has a pre-out bypass feature, if, for example, you wish to connect an active subwoofer or active loudspeakers.

As with the PRE550, should you wish to use your PC as a source, a driver download is required. It is available from the link below. With a volume level readout which triggers requests for information, we would encourage you to read the article on Understanding 0dB – also available ifrom the link below.
