The optional EXH-6 Dual XLR/TRS Combo capsule gives you 2 additional XLR/TRS combo inputs, allowing you to connect up to six discrete signals from external microphones, instruments, mixers or portable music players, making the Zoom H6 the smallest six-track recorder on the planet

Both EXH-6 inputs are combo jacks that accept either XLR or ¼" balanced (TRS) or unbalanced (TS) connectors. They can handle both mic- and line-level signals, which means that you can connect either microphones or line-level devices like mixers, portable music players, electronic keyboards, or electric guitars or basses with active electronics (passive electric guitars or basses can also be connected with the use of a mixer or effects device). Internal switching contacts automatically detect the circuit of choice

Each EXH-6 input offers a dedicated analog gain control knob as well as a -20dB pad that allows you to prevent distortion even when high-level signals are introduced; in fact, with the use of the Pad switch, the H6 can input 30dB louder signal and 14dB softer signal than any other Handy Recorder model. In addition, a built-in instrumentation amp allows signals to be transmitted with minimal noise even when long cables are used.
