Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.
The XL-AES is an optional accessory for the Scorpio, 888, and 833 that provides 8 channels of AES3 audio connectivity through four heavy-duty TA3F input jacks. The accessory mounts directly to the expansion port on the mixer-recorder’s top panel and features a rugged milled aluminum enclosure for years of reliable use.
The XL-AES appears in the Channel Input Source menu with all other possible input sources. Any of the 8 audio channels from the XL-AES may be routed to any channel on the mixer-recorder.
