Hosa GPP-290 Adapter, 1/4 in TRS to 1/4 in TS

The Hosa GPP-290 is an audio adapter with a 1/4 in TRS plug on one end and a 1/4 in TS jack on the other. It takes a mono source and applies it equally to the stereo left and right sides of the TRS connection. The all metal barrel plugs directly into the gear with no cable in between, which suits headphone jacks and other stereo inputs fed from a mono cable.
