The RA62HA is a six-channel headphone amplifier for high quality audio monitoring. It is intended for sound reinforcement, studio, choir, and other applications where high channel to size ratio is desirable.

Up to six individual monitor mixes may be listened to via the rear panel TRS stereo insert jacks. The RA62HA has an FR4 double sided circuit board and painted steel chassis. It has six 1/4" stereo headphone outputs, one 1/ 4" TRS stereo input located on the front panel. Right and Left 1/4" Input jacks, and six 1/4" Insert jacks are located on the rear panel.

HEADPHONE AMPLIFIER RA62 Determine which input configuration you will use; either discreet right/left, TRS stereo, or mono. For a discreet right/left input configuration, connect a 1/4" TS plug containing the "Right" portion of the stereo signal to the Right Main Input. Connect a 1/4" TS plug containing the "Left" portion of the stereo signal to the Left Input. For a TRS stereo input configuration, connect a Tip-Ring-Sleeve stereo plug into the front panel STEREO IN input. This cable may come from a mixer's headphone output for example. To send a mono signal to the RA62, connect a 1/4" Tip-Sleeve plug into either the Right or Left input and press in the front panel MONO/STEREO switch. This mono signal will be fed to both the right and left sides of the headphone outputs. [. . . ] CHANNEL INSERTS: INSERTS The inserts have been provided so you can directly access each headphone output with its own program material. The inserts require Tip-Ring-Sleeve connectors, with right and left signals on the tip and ring respectively. If you use a TS mono plug - you will only hear sound out of one side. When these insert jacks are used, the main Right/Stereo and Left/Mono, as well as the Aux Inputs - are disconnected. [. . . ]
