The four-position Ribbon Level control switch is used to adjust the monitor's 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 R8a is flat when the Ribbon Level control is set to the “0” position.

The volume control is used to adjust the 

overall output level of the Rubicon R8a.  

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 Rubicon R8a features a full comple-

ment of input connectors providing 

easy installation with a variety of audio 

devices like recording consoles, hard 

disk recorders, CD players and computer 

sound cards, to name a few. The following 

section details the Rubicon R8a's input 

connectors. In addition, there is a detailed 

cable-wiring diagram on page 12.

BALANCED XLR AUDIO INPUT - The 

Rubicon R8a 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.
