Thread: Aavik Firmware Infos

Does anyone here have the current firmware versions for the U and/or D series of components ( I have U280, D180..along with a decent amount of Ansuz kit). Finally, is there any way to upgrade the firmware myself or do I need to go back to the dealer (60 miles away).

Thanks for any guidance—r.

Hello AGD_Fan and welcome to AudioShark.

The first course of action in situations like this is to reach out to your local dealer for support.

There should not be any audible pops or clicks when switching into HT bypass mode.

What’s your current software version? That can be seen in the Menu options.

Likely your Aavik U-280 needs updating through the FTP server. Firmware updates are done via the RS-232 connection on the rear panel. Your local dealer will be able to physically assist with that or may be able to guide you remotely if you are handy with computers.

I understand 034 is the latest firmware version for U-Series (U-180 / 280 and 580).

Your dealer should be able to assist with instructions on how to download the latest control software version from the Aavik Acoustics FTP server.

You will need a Windows PC (Windows XP or later), and either a DB-9 male to female serial cable (if the PC has a built-in serial port), or a USB to serial converter cable.

Further testing showed the “pop” I was hearing in my tweeters in HT bypass was present on all inputs if the level was higher than about 30…and HT had no pop when the default recommendation of 0 was replaced by a level of 50…which did not work for my intended HT setup. A damned shame. I’m currently testing an MBL N51 Integrated with HT bypass—but missing the aesthetics of my Aavik. The MBL has a great soundstage and really works well with the 803D4s…

Thanks for the update. Please let us know what the outcome of the Aavik U-280 service is. There should not be any audible pops or clicks when switching into HT bypass mode or switching between any inputs for that matter.

I personally love the aesthetics of the MBL N51. The piano black/gold finish is grand but a bit old fashioned (IMHO), however the piano white/chrome finish is sublime. I’m a fan of their omni loudspeakers too which really impress with large scale orchestral music. Huge soundstage.
