Thank you for your purchase of the Rolls RA62 Stereo Headphone Amplifier.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. Since the MONO/STEREO switch is after the pan control, it will mix 2 MONO signals and their balance can be adjusted with the Pan control. 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. There are two Auxiliary Inputs (right and left) located on the rear panel. Each channel has a Volume control, panning and balance is controlled via the Pan control located on the front panel, and the unit features a MONO/STEREO switch. 2 DESCRIPTION FRONT PANEL PAN OUT OUT OUT OUT OUT OUT STEREO INPUT PWR VOLUME VOLUME VOLUME VOLUME VOLUME VOLUME MONO STEREO CONNECTION Connect the AC cord to a properly grounded ac outlet. 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. The Aux Inputs are connected in the same manner as the discreet right/left input configuration listed above. Note: Descriptions for Channel One through Channel Six are identical. OUT 1 - 6 : 1/4" Tip-Ring-Sleeve jack for connection to a standard pair of headphones. VOLUME 1 - 6: Controls the amount of output signal from the indicated channel. MONO/STEREO SWITCH: When this switch is pressed in, the Right and Left channels are summed together providing a mono output signal. PAN: Controls the relative amount of signal sent to the Right and Left output channels. STEREO IN: 1/4" TRS input jack which paralells the rear panel Right and Left input jacks.

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. Only the stereo signals sent to the Insert jacks go to that corresponding output. CAUTION: Plugging a mono 1/4" TS plug into the Headphone Outputs may cause permanent damage to the unit because one side would be shorted to ground. Never plug a mono plug into any of the Headphone Outputs. Tip Ring Sleeve (ground) 3 4
