SAT 6. 5 MK II Mounting & Placement Center of the tweeter Monitor mounting and placement is often an afterthought, but in order to get the best imaging and overall performance from the SAT 6. 5 MK II, it is important to place the speakers correctly. Monitoring Height: Figure 2 shows the ideal monitoring height, with the SAT 6. 5 MK II located perfectly at seated ear height. If this is not possible, tilting the cabinet at the listening area can improve high-frequency coverage. Monitoring Angle: The recommended position for the monitors is based on an ITU standard and sets the speakers at 60 degrees from the listener, forming an equilateral triangle (a triangle with equal sides) - See Figure 3. Fortunately, this setup eliminates most of the math and is easily simplified to the following guidelines: If you want to sit 2 meters from the speakers, place the speakers 2 meters apart. Wall Mount Options: The SAT 6. 5 MK II is compatible with OmiMount® 60 Series brackets, via the 1/4 X 20 inserts located in the bottom of the cabinet. The OmniMount® type 60 brackets are designed to support up to 60 pounds of weight when properly installed. Please visit www. omnimount. com for more information, including detailed mounting instructions. Please see page 14 [Cabinet Dimension] for more information on insert locations.

System Signal Flow & Connections 2. 1 SYSTEM SIGNAL FLOW & CONNECTIONS Above is a simple diagram showing a Sky System One / 2. 1 Monitoring system. The diagram shows a stereo signal going from the source, to the subwoofer and from the SUB outputs to the inputs on left and right SAT 6. 5 MK II monitors. Cable and connector wiring Use high-quality, shielded cables to connect your console, workstation or other sources to your Blue Sky Monitoring system. Foil-shielded cables, such as Belden 8451, 8761, or 9501 should do quite well. Other high quality cables are available and those that incorporate better shielding will yield an overall higher noise rejection, lowering your systems susceptibility to external interference. Another important tip to keep in mind when wiring your system is to route all line level cables away from the AC and other power sources, this will reduce the probability of having AC hum emanating from your monitoring system. Page 9 9. Expanded Calibration Guide Step 3 Step 4 Mute everything and make sure the 1kHz tone is OFF . Now that the system has been electrically calibrated turn ON the 2. 1 System. Make sure there is nothing coming from the right channel (or any other channels). Because this signal is bandwidth limited, you don't have to worry about turning the sub off. If you have a master monitor level control (console etc), you can set the SAT 6. 5 MK II gain control at reference and then adjust the monitor gain control for 85 dBc. The other method is to set master monitor level (console etc. ) to the position you want reference level to be (such as unity gain as determined by the electrical calibration process in beginning of these instructions) and then use the volume control on the SAT 6. 5 MK II to set 85 dBc. If you use this method you should make a note of the positing, so you can always go back to the new "reference level" if the pot gets moved.
