USB
The USB-interface (USB 1.1) allows for the mixer to be used as an audio interface. In other words, audio recording and playback can be done through a connected computer with Windows Operating System (Windows XP, Vista, 7, 8) and Apple Macintosh OS 10.5 or higher. Separate drivers are not necessary for the installation. Once connected to a suitable USB port on your computer (USB 1.1, USB 2.0), the drivers are automatically installed, the audio interface is detected as "USB Audio CODEC" interface on both Windows and Apple Macintosh computers.
The recording signal consists of the sum signal and is sourced before the master level control and the max level control, and is therefore independent of it. Audio playback is via the line channel INPUT 1. For this, the switch 55 must be pressed on the back panel (USB) and the switch 8 (LINE) on the front of the unit should not be pressed.
USB / LINE
Switch for selecting the signal source for the line channel INPUT 1. In pressed position, the USB-interface (54) is selected, if not pressed, the line input (51) is selected as the signal source.
GROUND CONNECTION
Screw terminal for connecting the ground wire of a turntable.

MANUFACTURER'S DECLARATIONS:
MANUFACTURER'S WARRANTY
This warranty covers the Adam Hall, LD Systems, Defender, Palmer, and Cameo brands.
It applies to all products distributed by Adam Hall.
This warranty declaration does not affect the statutory warranty claims against the manufacturer, but expands them with additional warranty claims vis-a-vis Adam Hall.
Adam Hall warrants that the Adam Hall product that you have purchased from Adam Hall or from an Adam Hall authorized reseller is free from defects in materials or workmanship under normal use for a period of 2 or 5 years (please inquire on a product-by-product basis) from the date of purchase.
The warranty period begins on the date on which the product was purchased, proof of which must be produced (through presentation of the invoice or the delivery note with the date of purchase) in the event of a warranty claim. Should products of the brands named above be in need of repair within the limited warranty period, you are entitled to warranty service according to the terms and conditions stated here.
During the Limited Warranty Period, Adam Hall will repair or replace the defective component parts or the product. In the event of repair or replacement during the Limited Warranty Period, the replaced original parts and/or products become property of Adam Hall.
In the unlikely event that the product which you purchased has a recurring failure, Adam Hall has the right, at its discretion, to replace the defective product with another product, provided that the new product is at least equivalent to the product being replaced with regard to the technical specifications.

- damage to devices operated outside the usage parameters stated in the documentation included with the product - damage due to the use of replacement parts not manufactured, sold or recommended by Adam Hall, - damage due to modification or servicing by anyone other than Adam Hall.
These terms and conditions constitute the complete and exclusive warranty agreement between you and Adam Hall regarding the Adam Hall branded product you have purchased.

LIMITATION OF LIABILITY

Adam Hall is not liable for any damages caused by the product or the failure of the product, including any lost profits or savings or special, incidental, or consequential damages. Adam Hall is not liable for any claim made by a third party or made by you for a third party.
This limitation of liability applies whether damages are sought, or claims are made, under this Limited Warranty or as a tort claim (including negligence and strict product liability), a contract claim, or any other claim, and cannot be rescinded or changed by anyone. This limitation of liability will be effective even if you have advised Adam Hall or an authorized representative of Adam Hall of the possibility of any such damages, but not, however, in the event of claims for damages in connection with personal injuries.
