About Hear Technologies Hear Back OCTO

While the Hear Back OCTO 4-Pack Personal Monitor Mixer System is the next step in the evolution of 8-channel personal monitoring systems, it offers more than just an upgrade. This advanced system, inspired by the Hear Back PRO system, is designed to revolutionize your monitor mixing experience, whether on stage or in the studio.

The Hear Back OCTO system is equipped with high-quality 24-bit D/A converters and offers improved audio quality and system performance. It's designed to give you precise control over your mix, saving you time and ensuring you get the sound just right on the first attempt. This professional-grade system is versatile, perfect for use with headphones, wired and wireless in-ear monitors, or conventional floor monitors.

The system includes a durable hub, four reliable mixers, four high-speed CAT5e cables, and a DA-88 cable. The hub is designed to supply signal and power to a maximum of eight mixers, and can be daisy-chained using the HearBus In/Out for virtually unlimited system size. It accepts both analog input signals from an audio mixer and ADAT input from digital audio workstations, digital recorders, or digital mixers.

The mixers are equipped with capacitive touch link buttons and offer local control of up to 10 channels of audio. They feature a master volume control, a built-in standard mic stand mount, bus status indicator, headphone amplifier fault indicator, and mono/stereo link indicators. Balanced line outs and a stereo AUX in allow for expanded numbers of mixers and drum module/metronome input.

All connectors are conveniently located on one end for easy access, and the system is 100% backwards compatible with the original Hear Back system. It's also compatible with the Hear Back PRO system via an optional PRO Hub ADAT Card. The compact size and rack-mountable design make it an ideal choice for professional settings, offering easy installation and organization.

Experience the difference with the Hear Back OCTO 4-Pack Personal Monitor Mixer System, designed to deliver superior sound quality and ease of use.
