Why Choose WBS?

I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world.  Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!

Great for Radio, TV, Film, and Music Productions
The HX-3 accepts balanced XLR line-level inputs or unbalanced 1/4-inch and 1/8-inch stereo inputs. Its 1/4-inch loop-out can connect multiple HX-3’s for additional headphone outputs. Headphones are connected to panel-mounted 1/4-inch stereo connectors.

The HX-3 has a durable aluminum chassis to withstand the punishment of field and studio environments. The unit is powered by inexpensive batteries (two-AA) or external 5-18 VDC.

The HX-3 can add headphone outputs to the 552, 302, MM-1, and USBPre-2.
