Attached to an HDS-6 (available separately), the Furman HR-6 allows musicians to customize their headphone or monitor mixes and levels. Accepts up to 7 units. Each unit provides 5 volume controls: 4 monaural for mixer channels or buses, plus one for stereo mix or effects. A Submix Include/Exclude button mutes the 4 monaural controls allowing each HR-6 user to hear stereo source only without having to alter the other settings. The unit clamps to any mic stand (hardware included).
