Fever-class performance, affordable price. Can with Sound Devices HX-3 ratio right.
This headphone amplifier functions a bit like a big screen monitor, you can amplify the signal to a very high magnification, so you can easily hear the noise hidden in a quiet place, like a zoom-focus the same.
It can be used for filming the scene, so that the contents of the recording can be assigned to listen to the director and other staff, and can be one of a cascade, to more people listen.
For portable electronic devices such as handheld recorders, various media players, general headphone output is not very strong, open to the maximum sound can barely hear what the big signal, if want to hear the subtle sounds paragraph often unable to do so. Through this headphone amplifier, headphone output from the ordinary to send over, can greatly magnify, still you can hear enough volume to fully grasp your recordings.
Like filming needs a good monitor, sound recording also need enough good monitoring system, which sets a high standard headphone amplifier with a variety of headsets, including the Superlux HD662, HD668, you will no longer return to the cutting room only to find the bottom noise much of a problem, the site will be able to master
