INTRODUCTION
Thank you for your purchase of the Rolls RA102 Professional Stereo Headphone Amplifi er. The
ROLLS RA102 is a ten-channel headphone amplifi er for professional audio monitoring. A variety of
input options are available including RCA and balanced XLR separate right and left. The JOIN section
is for connecting more than one RA102 directly together without any signal loss or impedance issues.
You can connect many RA102’s together with the JOIN function. Each channel has a 1/4” headphone
output jack on the rear for professional installations and a 1/8” jack on the front for ease of operation
(both jacks may be used at the same time if needed).
Determine which input confi guration you will use; either RCA or XLR stereo. Mono can be achieved
by connecting the mono input signal to both left and right inputs at the same time.
For a discreet right/left input confi guration, connect a balanced XLR, or RCA plug containing the
”Right” portion of the stereo signal to the Right Main Input. Connect a balanced XLR, or RCA plug
containing the “Left” portion of the stereo signal to the Left Input.
For a TRS stereo input confi guration, connect a Tip-Ring-Sleeve stereo to dual Tip-sleve (mono) RCA
jack cable. This is a very specifi c jack referred to as a insert jack and must be purchase at a specialty
store, to the rear panel LEFT and RIGHT RCA Input’s on the RA102. This cable may come from a
mixer’s AUX output for example.
To send a mono signal to the RA102: connect a mono XLR or RCA to both the LEFT and RIGHT
inputs at the same time this will require a specialty cable. The mono signal will be fed to both the right
and left sides of the headphone outputs.

JOIN EXPLANATION:
The JOIN section is for connecting RA102’s directly together so you can use one source plugged into
the fi rst RA102 and by connecting them with the JOIN in and outs you can have as many headphone
outs as you have units.
To properly connect the JOIN: Plug source material into the fi rst RA102, then plug a TRS 1/4” cable
(also referred to as a 1/4” stereo cable) from the JOIN OUT of the fi rst unit into the JOIN IN of the
second unit. Repeat the JOIN in and out scheme for as many RA102’s as you need, only plugging the
source material in the very fi rst unit in the chain.
Connect the AC adapter to an outlet with the proper voltage. For installations there is intentionally no
Power switch designed on the front of the unit. To turn the RA102 o the power must be terminated
at the adapter. The RA102 was designed for professional applications were most functions are not
accessed from the front. In these applications it is acceptable for the unit to be left on. No damage will
occur to the RA102 in this application, it was designed for it.
This is a MONO
jack and should
never be plugged
into the Head-
phone Output of
a RA102.
This is a TRS or
stereo jack that
is compatible
with the RA102
Headphone
Outputs.
