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.

DESCRIPTION
FRONT PANEL
Note: Descriptions for Channel One through Channel Six are identical.
OUTPUTS 1 - 6 : 1/4 and 1/8 (3.5 mm) Tip-Ring-Sleeve jacks for connection to a standard pair of ” ”
headphones or earphones. These jacks may be used simultaneously.
CLIP: Red LED indicating circuit overload in that channel.
MIX: Adjusts the relative amount of signal from the Main Inputs and the Direct Input of that
channel.
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.
MAIN INPUT PAN: Controls the relative amount of Right/Left signal sent to the Output channels
from the Main Input.
MAIN INPUT: 1/4” TRS input jack - parallels the rear panel Right and Left 1/4’ Input jacks.
POWER: Push switch - turns the RA62c on and o .
POWER LED: Indicates that the RA62c is connected to the power supply and is on.
REAR PANEL
12 VAC INPUT: Connects to the Rolls PS12 AC adapter (Included).
INPUTS:Left and Right - Balanced XLR jacks
- 1/4 Balanced / Unbalanced jacks”
- RCA Unbalanced jacks
Note: Descriptions for Channel Six through Channel One are identical.
DIRECT INPUT: 1/4 TRS jacks which directly access the channel’s heaphone output circuitry, and ”
is mixed to the corresponding channel via the channel’s MIX control. This is a stereo jack and
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.
