Setting up the Rubicon R5a and R6a
Background on the Rubicon R5a and R6a Studio Reference Monitor
The Rubicon R5a and R6a are self-powered near-field reference monitors, featuring robust power, advanced
electronics and custom designed drive units. For pristine high’s, the Rubicon 5a and 6a boast a 1-inch by 2-
inch velocity ribbon tweeter. The Rubicon ribbon tweeters are constructed using a Kapton diaphragm with
vaporized aluminum applied to the surface. The diaphragm is then set between an array of neodymium mag-
nets creating an opposing magnetic field. Since the ribbon is both the coil and the diaphragm, the diaphragm
can accelerate and decelerate quickly resulting in un-matched transient response. Unlike conventional dome
tweeters, the ribbon tweeter exhibits no coloration due to resonance, as well as, extremely low intermodula-
tion and FM distortion. The result is a wide linear response producing high frequencies that are sweet, while
clear and accurate. For the low frequency response, the R6a employees a 6.5-inch, copolymer low frequency
drive unit with butyl rubber surround, and for the R5a, a 5-inch, copolymer, low frequency butyl rubber sur-
round drive unit. Both woofers are well matched to the tuned enclosure and provide punchy and focused
bass frequency response.The monitor’s crossover has been carefully designed with high quality components
insuring a linear frequency and phase response. The Rubicon R5a and R6a enclosures are constructed from
MDF (Medium Density Fiberboard) and are finished in scuff resistant, textured paint. The monitor’s enclo-
sure also includes a tuned vent port that provides extended low-end response, and with a low turbulence
design, the low frequency driver can move freely with minimal effect on the overall impedance. On the rear
of the enclosure, you’ll find Rubicon R5a or R6a’s control panel, which features a variety of input connections
including both XLR balanced input, and a1/4-inch TRS balanced input plus an RCA unbalanced input on the
R5A . These inputs are connected to Rubicon R5a or R6a’s internal bi-amp power module providing 75 watts
of power for the low frequency woofer, an active crossover, and 25 watts of power for the high frequency
tweeter for the R6a, and 50 watts for the low end and 25 watts on the high end for the R5a. You will also find
the pre-amp controls, including VOLUME knob, used to adjust the overall level of the internal power amplifier,
as well as the innovative Ribbon Level control. This four-position switch allows the mix engineer to contour
the high frequency response of the monitor allowing you to adjust for room acoustics or listening preference.
The Rubicon R5a and R6a have been designed to provide flat, accurate monitoring, and at the same time, to
provide an adjustable response curve so that the sound of other popular near-field monitors can be easily
emulated.
Positioning the Rubicon R5a and R6a
Near field monitoring has become the choice of many engineers in large and small studios because it mini-
mizes the effect of room acoustics. This is especially important in today’s project studios since the budget
for room acoustics is often close to nothing. By positioning the reference monitors in the near field (close to
the listeners), you can greatly reduce the effects of room acoustics. The most important considerations when
evaluating the effects of room acoustics are reflective surfaces that are around the monitoring area. These
can include flat tabletops, glass mirrors or
framed pictures, large open walls and even
the surface of your mixing console. Mostly
all reflecting sound will eventually reach
the listening position, but since it is slightly
delayed from the direct source, the result is
random cancellation of some frequencies, or
comb filtering. If possible, remove any and
all reflective surfaces. You may also want to
hang some acoustic foam on walls that are
close to the monitors. When positioning the
monitors you’ll want to set up what is com-
monly referred to as the “mix triangle”. In this
ideal configuration, the space between the
left and right monitor is equal to the dis-

Setting up the Rubicon R5a and R6a
A Moment of Reflection
When choosing the height of your monitor system, be careful to avoid reflections off the surface of the mixing
console. (Figure 3.) These reflections arrive at the listening position slightly delayed from the original sound
resulting in strange cancellations and overall unpredictable response. Visualize straight lines representing the
beams of sound radiating from the monitors and choose a height that reduces the occurrence of reflections
that will end up in the prime listening spot. (Figure 4.) In most cases, the ideal position is slightly behind and
above the mixing console’s meter bridge.
Prime Listening Spot
Speaker Orientation
The Rubicon R5a and R6a’s can be used in either the vertical or horizontal position. When using the monitors
in the horizontal position, be certain to place the left and right side tweeters on the outer most sides. (Figure
2) This will improve the stereo imaging and bass response by increasing the coupling of the low-end drivers.

Connecting the Rubicon R5a and R6a
• Lower your mixer’s master outputs to all the way off.
• Connect the mixer’s left Control Room output to the left-side Rubicon R5a and R6a LINE INPUT and
the mixer’s right Control Room output to the right-side Rubicon R5a and R6a LINE INPUT.
• Set the Rubicon R5a and R6a’s input Volume control to the 2 o’clock position.
• Run an audio signal (like some music from a CD) through your mixer and raise the Control Room level
to a comfortable listening level.
Rubicon R5a and R6a Quick Connections
Note: Before plugging in and turning on, remember the “last on first off” rule of power amplifiers (and pow-
ered monitors). When powering up your system, be sure that all the wires are connected, turn your mixer and
any other outboard gear on, and then last turn your Rubicon R5a or R6a’s on. When powering down, turn your
Rubicon R5a or R6a’s off first and then your mixer and outboard gear.
The Rubicon R5a and R6a connections can be made via one of the three rear panel Audio Inputs. You can
use RCA inputs for unbalanced -10dBV level signals, or either the 1/4-inch or XLR inputs for balanced +4dBu
level signals. Follow the simple steps and diagram below for a quick connection using a standard recording

Operating the Rubicon R5a and R6a
Rubicon R5a and R6a Control Panel
The Rubicon R5a and R6a’s rear control panels are where you will make your connections for both
AC power and audio signals. The rear panel also contains the controls to make adjustments to the overall
volume and frequency response curve. The following section details the rear panel controls and connec-
tions.
Powering the Rubicon R5a and R6a
Since the Rubicon R5a and R6a are active studio monitors with an on-board power amplifier and elec-
tronic crossover, it is necessary to connect the unit to an AC power supply. Make sure that the main Power
switch is set to the off position and connect the supplied IEC power cable into the AC inlet.
Things that go Hum!
When running power cables, be careful not to run the AC power cords or AC extension cords in paral-
lel to your input cables. This will
help reduce any AC hum that can be
picked up. If your have to cross an AC
line with an audio line, try to cross
them at a 90 degree angle for the
least amount of induced hum. Using
the Rubicon R5a and R6a’s balanced
input connectors will greatly protect
against the induced hum thanks to
the common mode rejection (the
induced hum is phase canceled) that
its balanced input circuit provides.
POWER SWITCH – The POWER
switch is used to turn on the Rubicon
R5a and R6a’s active electronics.
When set to the on position, the
internal LED will illuminate green,
indicating the Rubicon R5a or R6a is
powered up and ready for operation.
The Rubicon R5a and R6a also have
a "rubi-red" LED which illuminates
showing when the unit is powered
up.
AC INLET - Connect the supplied IEC
power cable here.
The Rubicon R5a and R6a’s rear
panel provides two important controls for adjusting the overall sound of the monitor, RIBBON LEVEL and
Volume. Eventually, you will adjust these controls to your preferable position and “set it and forget it”.
That’s assuming that the monitors remain in the same spot, in the same studio. If you take your monitors
to other studios you may find the controls extremely useful in adjusting the sound for the new room.

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.

Connecting to the Resolv120a Subwoofer
Rubicon R5a and R6a with Mono Sub
Adding a subwoofer and extended low frequency response to your Rubicon R5a or R6a system is easy using
the Rubicon R5a or R6a’s LINE LEVEL inputs. Below is a typical system set-up using the Samson RESOLV 120a
or Sub88 with a mixer and a pair of Rubicon R6a satellite speakers. The Rubicon R5a and R6a’s inputs utilize
industry standard RCA connectors. For a detailed wiring diagram, see the section “Rubicon R5a and R6a
Connections” on page 57. Follow the steps in the diagram below to set up your system.
• Lower your mixer’s master outputs to all the way off.
• Connect the mixer’s left output to the RESOLV 120’s LEFT LINE INPUT and the mixer’s right output to
the RESOLV 120’s RIGHT LINE INPUT. Now connect the RESOLV 120’s LEFT LINE OUTPUT to the input
of the left Rubicon R5a or R6a, and the RESOLV 120’s RIGHT LINE OUTPUT to the input of the right
Rubicon R5a or R6a.
• Run an audio signal (like some music from a CD) through your mixer and raise the level to a comfort-
able listening level.
• Now adjust the SWEEP control to the desired frequency. You can also use your ears by adjusting the
SWEEP control to the frequency that sounds good to you. A good place to start is about 70 Hz.
