Zoom EXH-8 4-Channel XLR Expander Capsule for H8

The Zoom EXH-8 is an external XLR input capsule made specifically for the Zoom H8 Handy Recorder. It adds four XLR input channels through the H8 capsule connection, expanding the recorder for sessions that need more microphone or mixer feeds. It is a practical option for podcasters, musicians, location recordists, and production teams working with multiple sound sources.

Each of the four added inputs has its own level control, making it possible to balance connected sources directly at the recorder. Dedicated track buttons allow the four EXH-8 channels to be turned on or off individually. This layout supports organized multi-source recording without relying on a separate external mixer for basic input-level adjustments.

The EXH-8 accepts signals from microphones and mixers, including dynamic and condenser microphones. A separate -20 dB pad switch is provided for each input to accommodate stronger line-level sources. When used with equipment based around a +4 dBu standard output level, the pads help prevent input overload.

Condenser microphones can be used through the EXH-8 when an external power supply is connected to the capsule. Its power indicator shows when external power is connected and phantom power is available. This makes the capsule suitable for setups that combine multiple microphone types or mixer outputs.

Installed on a compatible Zoom H8, the EXH-8 adds four inputs to the recorder's available input system for up to 10 total inputs. It is part of Zoom's Capsule System 2.0 platform and replaces the H8's installed capsule while in use. The result is a focused expansion path for users who need more XLR channels without changing recorders.

Key Features

• Four XLR Inputs: Adds four external XLR input channels to a Zoom H8 recorder.
• Individual Level Controls: Provides a dedicated input volume knob for every added channel.
• Per-Channel Pad Switches: Supplies -20 dB attenuation for higher-level connected sources.
• Condenser Mic Support: Enables phantom power when an external power supply is connected.
• Track Buttons: Lets you turn each of the four EXH-8 tracks on or off.
• H8 Capsule Integration: Connects through the Zoom H8 interchangeable capsule connection.

Design & Installation

The EXH-8 design places four XLR inputs, four input volume controls, four track buttons, and four pad switches in one recorder-mounted expansion capsule. Zoom does not state a housing material in the confirmed product documentation. A power indicator provides a visible confirmation when external power is connected for phantom-power operation.

Install the EXH-8 in place of the H8's existing capsule, then connect microphones or mixer outputs to inputs 1 through 4. Use the individual controls to set levels, and engage the -20 dB pads when connecting +4 dBu line-level equipment such as mixers. For condenser microphones that require phantom power, connect an external power supply to the capsule; Zoom identifies the AD-17 dedicated AC adapter as an example.
