Operating the Rubicon R5a and R6a
Rubicon R5a and R6a Control Panel - continued
RIBBON LEVEL CONTROL
The four-position Ribbon Level control switch is used to adjust the monitors’ high-frequency response,
providing four equalization curves to select from. By using the Ribbon Level control, the Rubicon’s high
frequency response is adjusted with the application of a high-end tilt (equalization circuit) centered
at 12kHz, with selectable levels of –2dB, 0dB (flat), + 2dB and +4dB. You’ll find that the change is very
subtle. Many mix engineers prefer the sound of near field monitors with a little lift in the high frequency
response, some like more focus on the midrange, and therefore, desire a flatter or rolled off high frequen-
cy response. The best way to set the controls is what sounds good to you. Therefore, you should experi-
ment with the various settings to find the combination of the Ribbon Level and Volume controls you like.
To do this play several CD’s of music that you are familiar with. Remember, if you think you’re getting lost,
the Rubicon R5a and R6a is flat when the Ribbon Level control is set to the “0” position.
VOLUME CONTROL
The volume control is used to adjust the
overall output level of the Rubicon R5a
and R6a. When operating the unit for the
first time, start with the volume control
set all the way off. Slowly raise the Volume
control to reach a comfortable listening
level.
The Ins and The Outs
The Rubicon R5a and R6a features a full
complement of input connectors pro-
viding easy installation with a variety of
audio devices like recording consoles,
hard disk recorders, CD players and com-
puter sound cards, to name a few. The
following section details the Rubicon R5a
and R6a’s input connectors. In addition,
there is a detailed cable-wiring diagram
on page 13.
BALANCED XLR AUDIO INPUT - The
Rubicon R6a features a female XLR con-
nector that will accept balanced or unbal-
anced +4dBU line level signal. If you are
using a mixer that has balanced outputs on XLR connectors, you can make the connections via standard
XLR (microphone) cable.
1/4-INCH PHONE AUDIO INPUT – A balanced TRS (Tip, Ring, Sleeve) 1/4-inch phone plug is used to con-
nect balanced or unbalanced line level signals. The 1/4-inch input is a switching jack, so when a 1/4-inch
connector is inserted into the jack, the RCA and/or XLR inputs are switched off and the 1/4-inch input
is switched on. This provides a convenient patch-point for quick insertion of a secondary input signal
source for testing or expanded operation.
RCA AUDIO INPUT – The RCA input accepts unbalanced signals used to connect signals from unbal-
anced –10dBV devices.
