Bose 502C System Controller, tested and working. This is the EQ and crossover that makes Panaray 502A speakers sound the way Bose voiced them, with settings for full range or 2-way with the 502B bass module.

Single rack space, two XLR inputs with a -10/+4 switch, high and low XLR outputs per channel, and an LF trim. Light marks on the rack ears from mounting. The rest is clean.

I also have four 502A speakers listed. Message me if you want the whole system and I'll put together a bundle price.

I'll pack it the way I'd want it packed if I were buying it, and it ships with tracking within two business days.
