The RockBoard® HA 4 is a very compact headphone amplifier which can distribute a stereo input signal to four separate headphones. Each of the four output channels has its own amplifier and its own volume control and delivers professional quality audio to each headphone.
When you need more monitoring capacity, the Mackie HM-4 four-channel headphone amplifier has you covered. Perfect for studios, practice spaces, quiet stages and more, HM-4 can simply and effectively split a single audio signal to your entire band while maintaining full signal integrity.
The HA 1 In-Ear Monitoring Headphone Amplifier is the ideal partner for singers, keyboardists, drummers, guitarists, bassists and other musicians. It establishes the connection between the monitoring signal from the mixing console, instrument or amp and your own headphones.
