In many live environments, floor monitors can't be heard. A musician might be better off using headphones. However, more personalized audio control is required. The ART HeadTap provides quick and convenient tapping facilities to permit powering headphones directly from an amplifier. It's a passive device with an input to connect the PA or monitor amplifier and an output to connect the headphones. A volume control regulates the headphone level and internal resistors keep the unit's impedance high enough to protect the headphones. HeadTap also protects the amplifier from encountering too low a load impedance while powering tap units, the speaker system, or several tap units by themselves. It also works with a stereo headphone amplifier for use in recording situations when you want to add headphones for additional performers. Features: dual parallel 1/4" stereo/mono input jacks permit daisy-chaining taps and/or speakers; stereo/mono input selector button; dual 1/4" stereo/mono headphone jacks; level control; input impedance 150 ohms.
