Windows Drivers
Listen Hardware
AmpConnect 621™ - 
Latest firmware: 0.68
-	Driver: Included in SoundCheck installer
AmpConnect ISC™ - 
Latest firmware: 3.3.0.1 (3), AUAB: 1.17
-	SoundCheck (or SoundCheck ONE) 10.11, as a minimum, is required in order to control AmpConnect ISC™ via USB. AmpConnect ISC requires firmware version 3.2.4.6 or later to work with SoundCheck 10.11 and higher. AmpConnect units with S/N 367 and above have this firmware pre-installed. Units with S/N 366 and prior may require a firmware update. Please contact support@listeninc.com for instructions on determining the firmware version. 
-	Prior to S/N AC4277 (AUAB audio board firmware: 1.17), the headphone output polarity is inverted for both channels. Polarity tests using the headphone out will need to be adjusted accordingly.
-	Units with S/N AC432 and after (AUAB audio board firmware: 1.14), operate at 44.1 kHz and 24 bit depth in Windows 7 and above. (Prior to that S/N, 44.1 and 48 kHz are supported) [Windows XP: AmpConnect can only be used at 44.1 kHz sampling rate AND 16-bit]
-	As of SoundCheck 13, a new driver for AmpConnect ISC has been included in the SoundCheck installation process. The new driver will not work in versions prior to SoundCheck 13. To use AmpConnect ISC with SoundCheck 12 (and previously supported versions), you will need to manually rollback the device driver in Windows Device Manager.
-	As of S/N 1536, the “3 dB Down Point” default jumper position is 2 Hz (Jumper removed).
-	The default jumper setting for J20 & J28 is "No Jumper". The XLR inputs function as Balanced Inputs. S/N AC2402 to 2483 check jumper position.
-	SoundCheck 14 requirements: Default Windows WDM audio driver, minimum of SoundCheck 14 control driver, minimum of firmware 3.2.4.6. 
-	After installing SC 14, prior versions of SoundCheck will not have control over the device. Additionally, the serial number of the AmpConnect audio interface will not be read properly which changes the name of the device in the Hardware Editor.

AudioConnect™ - Latest Firmware: 1.61 Default Windows WDM audio driver
-	Minimum of SoundCheck 14 which includes control driver 
Firmware History:
-	1.61 - Sets headphone output polarity to match polarity of audio out. Used as of S/N 40501270108
-	1.60 - Remove HPF support, which is not present on the newer boards, and force HPF off on older boards. Add 4 more configuration data slots for Vp value storage.
-	1.58 - Audio output polarity corrected, Supports digital output muting
-	1.57 - Audio output inverted, does not support digital output muting
