Zoom EXH-8 Quad XLR Input Capsule for H8

The Zoom EXH-8 is an external input expansion capsule made specifically for the Zoom H8 Handy Recorder. It adds four locking XLR inputs, giving the recorder more capacity for multi-microphone sessions and sources from mixers. It is intended for users who need more than the H8's built-in input complement without changing to a separate recorder.

This capsule is a practical fit for podcast panels, location sound, rehearsals, live music capture, and other sessions requiring several individually connected microphones. With the EXH-8 installed, the H8 can accept up to 10 input channels in total. Each added input has its own control hardware for quicker level adjustment at the recorder.

The EXH-8 is designed to manage microphone and mixer signals rather than act as a microphone itself. It accepts dynamic microphones, condenser microphones, mixers, and other compatible XLR sources. Individual input volume knobs help balance varied source levels before recording.

Each of the four channels includes a dedicated -20 dB pad switch for handling stronger signals, including equipment using +4 dBu line level. This attenuation can help prevent overload when connecting a mixer or other professional line-level source. Track buttons for inputs 1 through 4 provide direct channel activation control.

Part of Zoom Capsule System 2.0, the EXH-8 mounts to the H8 through the recorder's capsule connection. Phantom power can be supplied to connected condenser microphones when external DC 5V USB power is connected to the capsule. This makes the EXH-8 a focused expansion path for H8 owners building a higher-input-count recording setup.

Key Features

• Capsule System 2.0: Integrates directly with the Zoom H8 recorder.

Design & Installation

The EXH-8 uses a purpose-built capsule format with four locking 3-pin XLR input connectors, four volume knobs, four pad switches, track buttons, and a power indicator. Zoom does not publish a material composition for the capsule. Its control layout places channel-specific adjustments directly on the expansion module for accessible setup in recording environments.

Install the EXH-8 by attaching it to the Zoom H8 capsule connection; no separate mounting hardware is specified. Update the H8 to firmware version 2.0 or later before use, and connect an external DC 5V USB power source to the EXH-8 when phantom power is needed for condenser microphones. Zoom AD-17 is identified as a compatible dedicated AC adapter, while ECM-3 and ECM-6 capsule extension cables are not supported with this capsule.
