Talk:Bose T4S and T8S ToneMatch® Mixers Compared to Bose T1® ToneMatch Audio Engine
I'll start with what we added. Channels 1,2,3 and 4 all have combo XLR-1/4" inputs. There's a channel 5 and 6 that is 1/4" TRS. The big one is stereo outputs and processing. Two digital ToneMatch outputs and parallel analog 1/4" TRS. Added a headphone jack. New magnetic cover, new 1/4"-20 threaded insert at the bottom for use with mounting hardware, tap-tempo delay, dedicated Aux reverb, a second Aux out, 3-band PEQ per channel, pan (of course), master out 5-band EQ, USB playback (WAV/MP3) from thumb drives, new industrial design. I'm probably forgetting something...
What did we take away from the T1 to the T4S? We removed the L1 and mic stand adapter (instead have a common 1/4"-20 insert), and we took away the preamp outs based on customer feedback that it was used very infrequently. Hope this info helps!
