Cooper Sound CS104 4-Channel ENG/EFP Field Audio Mixer – Professional Location Mixer

The Cooper Sound CS104 is a professional 4-channel portable audio mixer designed for ENG, EFP, film, television and location recording applications.

Built into a rugged metal chassis, the CS104 combines high-quality microphone preamplification, transformer-balanced audio circuitry and comprehensive monitoring in a compact field mixer. It features four input channels with individual level controls, a stereo master output and professional metering.

The CS104 is particularly well regarded for its audio quality, robust construction and suitability for demanding location recording work. The mixer incorporates Jensen input and output transformers, providing excellent audio performance and a wide dynamic range.

The original Cooper Sound documentation identifies the CS104 specifically as an ENG / EFP Audio Mixer.

The CS104 was also available with four balanced direct outputs, including versions/upgrades where the outputs could be configured pre- or post-fader, so I'd recommend checking the actual unit you're selling before listing this as standard equipment.
