INTRODUCTION

Thank you for your purchase of the Rolls RA62c Stereo Headphone Ampli er. The ROLLS RA62c

is a six-channel headphone/earphone ampli er for professional audio monitoring. A variety

of input options are available including 1/4”, RCA, and balanced XLR. 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. With the addition of rear panel Direct Input connectors, each channel may mix a

second stereo signal.

This manual assumes the user has a basic knowledge of audio electronic equipment.

requires a TRS stereo signal.

OUTPUT: 1/4” TRS jack - parallels the channel’s front panel 1/4” Output jack.

CONNECTION

Connect the AC adapter to an outlet with the proper voltage.

Determine which input con guration you will use; either discreet right/left, TRS stereo, or mono.

For a discreet right/left input con guration, connect a balanced XLR, 1/4”, or RCA plug contain-

ing the ”Right” portion of the stereo signal to the Right Main Input. Connect a balanced XLR,

1/4”, or RCA plug containing the “Left” portion of the stereo signal to the Left Input.

For a TRS stereo input con guration, connect a Tip-Ring-Sleeve stereo plug into the front panel

STEREO IN Input, or the rear panel LEFT Input. This cable may come from a mixer’s headphone

output for example.

To send a mono signal to the RA62c, connect an XLR jack to either Main Input, or a single 1/4 ”

Tip-Sleeve plug into rear panel Right 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.

DIRECT INPUTS

The unique RA62c Direct Inputs have been provided as a way for you to mix a separate, stereo

signal with the Main Input signal - giving each listener their own custom headphone mix.

To utilize this feature - connect a 1/4” TRS stereo signal, such as a monitor mix, to the listener’s

Direct Input. Mix the Main Input signal with this Direct Input signal via the front panel MIX

control

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.
