Simplifi 5075D Digital Amplifier

The unit contains not only the amplifier but also the sound card and requires only a USB connection. It's a Creative Sound Blaster Live 24 bit external card. Once you plug it all in, the unit automatically senses that your Media Center is on and turns itself on too.


Since I set up the HomeToys Small Spaces Demo using a Media Center I have been looking at the under-utilized Home Theater Receiver that I had to use just to amplify the 5.1 speaker system. The Windows Media Center takes care of everything else. At that time I looked for a simple 5.1 audio amplifier and had no luck.

Enter Simplifi Digital with the perfect solution. The 5075D is specifically designed to work with MCE systems. I wish I could say this is going to be a long and in depth review of this product ... but it's so simple that the review will be short and sweet just like the product.

Out of the box this is a nice looking component with no knobs or buttons whatsoever ... just a blue LED to indicate that it's on.

Connections couldn't be easier either. A nice little instruction manual walks you through the process. Connect the 5 speakers to standard terminals. RCA line to the powered subwoofer. USB connection to the Media Server and that's it.

The unit contains not only the amplifier but also the sound card hence the USB connection. It's a Creative Sound Blaster Live 24 bit external card. Once you plug it all in, the unit automatically senses that your Media Center is on and turns itself on too.

You need to install the drivers and a few Creative utilities from a CD and reboot the media center to get everything going.

All done. Easy listening ... great sound quality ... and throw away that other remote (volume control is via the MCE remote now and there is no need to power up a separate component since this one comes on automatically with the media center).

If you like to tweak, there are several settings available on the sound card utility software including:

  • Creative MediaSource™ Player/Organiser
  • Creative Device Control
  • Creative Speaker Settings
  • Creative EAX Console
  • Creative Graphic Equalizer1
  • Creative Surround Mixer
  • Creative WaveStudio®
  • Creative MiniDisc Center
  • Creative Diagnostics

I really think this is a product worth looking at if you are thinking of using MCE. Simplifi has several versions depending on the connections you prefer.

  • 5.1 Analog (RCA inputs))
  • 7.1 Analog (RCA inputs)
  • 5.1 USB
  • 7.1 ADAT ((TOSLINK optical connector)

MSRP for the 5.1 USB unit described here is $499.
