QSC Q-SYS Core 8 Flex network audio, video and control processor, part number FG-901462-00. Factory reset, updated to current firmware and bench tested before listing. The test results are below.

Setup. Factory reset with the ID button, then updated from firmware 10.0.2 to 10.5.0 through Q-SYS Designer. It ships with an empty design loaded, no admin password and no Q-SYS Reflect registration, so it is ready for your own design.

Bench test results.

Analog outputs, all 8 Flex Channels: a test signal sent to all eight measured the same level on every channel, with no clipping. A screenshot of the live meters is in the photos.
Analog inputs, all 8 Flex Channels: each channel switched to input mode comes up with a normal analog noise floor, so the input stages respond. Not tested with a live signal source.
USB-B: connects to a computer as a Q-SYS USB sound card. Audio recorded cleanly from the Core to the computer, and a test tone played from the computer arrived at the Core at exactly the expected level.
Network: LAN A and LAN B both tested working, with LAN A linked at 1 Gbps.
Control: accepts and runs designs from Q-SYS Designer and answers external control (QRC) on port 1710.
Core Manager web interface: loads normally in a web browser at the Core's IP address, with status, network, licensing, files and utilities all working. A screenshot is in the photos.
Health: processor 50 C and system 40 C at idle, fan running, no audio overruns, and the event log shows no warnings or errors.

Included, as shown in the photos:

AC power cord (US plug)
Rack ears, fitted to the unit
QSC Middle Bracket kit, sealed, for joining two half-rack units side by side
A second sealed QSC bracket kit
Adhesive mounting strip
The pluggable euroblock connectors for the rear panel, plus a bag of extra connectors: blue Flex Channel blocks, black GPIO blocks and RS232 blocks

Connectors and mounting hardware are commonly missing on used Cores and are sold separately, so they are worth having.

Not tested. The GPIO inputs and outputs and the two RS232 serial ports were not tested, and the analog inputs were not tested with a real signal source.

No warranty and no manufacturer support. This came to me second hand and I cannot supply proof of purchase, so QSC will not open a support case against this serial number. Sold as is, with no warranty. I am not selling or claiming any add-on feature licenses, and nothing that depends on QSC account registration is guaranteed. Price this as hardware.

Shipping. FedEx Ground, calculated from your ZIP code, shipped from Livermore, California. It goes out packed in an outer carton with padding.
