Another QSC KC12 adventure south of the border at Complejo Betel, Asambleas de Dios, in San Sebastian, El Salvador.
The KC12’s were deployed in a fairly hostile acoustic environment, 1500 person seating area that was 150' wide by 100' deep to the last seated congregant.
They sounded great, and the boxes still had plenty of headroom. All photos, video and system tech by Micah Navarrete.

For solo acts and those that wish to switch from acoustic guitar to electric guitar and want to not bring an amp or a modeler to the gig, but still want that amp sound, these boxes are key. They give you the sound while exhibiting a small form factor. We are dealers, the box is instock. Perfect holiday gift!
They are also a get out of jail free card for anytime your amp might fail, insurance!

The Direct-Drive is a combination amp simulator and DI box that provides a realistic amp sound through the PA, eliminating the need to bring an amp to the gig.

About ten years ago I helped out pal and client Michael Hunter, to install a new sound system in the Tariffville Elementary school. We repurposed a pair of speakers and an amp, added a QSC Touchmix 8, an 4 channel AKG Tetrad wireless all in a new wall mounted cabinet with a pair of Audio Technica hanging mics and a Radial media input at the Stage proscenium.
As of late crowding of the RF spectrum and some end user mishandling of the stick mics had opened the door to end of life for the AKG unit.
We sourced a really nice Shure SLXD4Q, 4 stick mics, 2 belt packs, 2 lavs and a headset mic for them. Cleaned up the system, installed the Shure components and wrote two new scenes and three new library presets for the various transmitters. It came out great and sounds better than ever!
