Free Upgrade to 8 Channel System With AmpConnect 621 Purchase

When you purchase our AmpConnect 621 multichannel audio interface, we’ll upgrade your SoundCheck system to 8 channels at no additional cost – that’s a saving of up to $1,500. This up-levels your system to a 6-in, 2-out multichannel system ideal for measuring mic arrays, automotive audio, noise canceling headphones and more. Used with the multichannel RTA in SoundCheck 20, you can view multiple signal paths simultaneously as well as calculate differences, averages and more in real time.

And if you don’t have a SoundCheck system yet, we’ve also got you covered ! We’ll discount any 8-channel software package by 25% when you purchase SoundCheck and AmpConnect 621 together.

Note: offers cannot be combined. Discounted pricing applies to a maximum of 5 systems. SoundCheck 20 is recommended for AmpConnect 621 control and full Multi-RTA functionality.
