2. Blue Sky is a philosophy. We design each product to represent the highest ratio possible of performance to cost, providing the highest value added to our customers. We will continually seek out opportunities to utilize the talent of the Blue Sky team to realize this philosophy. Our customer’s value requirements will always be our prime focus, and only those products that achieve our performance value ratio will earn the right to carry the Blue Sky logo.
4. A Tour of the BMC MK II - Main I/O 1. Power Switch - This switch controls the power to the BMC remote and all internal electronics. 2. 5.1 Channel Inputs - These XLR inputs should be connected to the 5.1 channel outputs of your console or digital workstation. The inputs are electronically balanced (Max input +24dBu). Do not connect more than one source to these inputs. Refer to the wiring table on page 11 for wiring custom cables and connectors. 5.
2 1 5. L(eft) / - / NO Button USER MODE: The “L” button activates the solo function for the “left output”. When a second I/O unit is connected, the solo function for the “left output #2” can be activated by holding this button down for 2 seconds. Solo can be cancelled by doing any of the following; activating the solo function on another channel, muting the system, or by pressing the “REF” / reference button.

System Gain, Sub Offset and Level Overview System Electrical Gain The input stage of BMC MK II is designed for a maximum input level of +24dBu (balanced or unbalanced) before clipping. The output stage will also drive a balanced 10K Ohm load to a maximum of +24dBu. However, because the BMC can add up to +6dB of gain to a channel to balance the system, there are situations where the BMC will clip.
. Software Features As mentioned in previous sections in this manual, the BMC MK II has two distinct operating modes - “USER MODE” and “SETUP MODE”. Below is a quick oveview of some of the basic guidlines for the operation of the BMC in these modes. On the opisiste page you will find a software flowchart detailing the operation of all the “SETUP mode” functions.
PRESET MENU: The BMC MK II has a total of 4 presets available. The presets store all level and calibration settings for the BMC, along with preset name, SUB level offset, bass-management IN / OUT and LFE GAIN. The main display will always display what PRESET is in current menu when in USER MODE and when not in MUTE, REF or SOLO mode, as shown below (in this case PRESET 1). When you scroll through the other profiles, it will ask you if you want to load the selected profile (show below).
9. 5.1 Speaker Placement Figure 1 Satellite Speaker Placement - MUSIC B The recommended monitoring angle for proper stereo imaging with music is 60 degrees between the left and right speakers. The center channel speaker should be located on axis with the reference monitoring position and both the left and right surround channel speakers should be at an angle of 110 degrees from the center line.
10. System Wiring Information & Diagram ,I N C. Use high-quality, shielded cables to connect your console, workstation or other sources to your Blue Sky BMC MK II. 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.
11. 5.1 System Calibration The following sysetm calibration instructions are for a bass-managed speaker system, such as Blue Sky’s ProDesk, Sky System One, or Big Blue system.
SETTING THE REFERENCE LEVEL Step 1 Step 2 Turn the master gain control knob until the SYSTEM GAIN equals the gain noted in step 4. Release the knob, being careful to not nudge it and then press YES, when the menu reapears. You have now successfully stored the preset “REF” level. Press CANCEL to exit setup and then press the REF button to confirm the setting is correct. The display will read “REF GAIN”, with the gain setting below (shown below). The REF LED will also be ON.

13. Dual BMC MK II I/O Unit Setup Important notes for this type of setup: The BMC MK II allows for two BMC MK II I/O units to be controlled by a single remote. This allows for up to 10.2 calibrated & bass-managed channels, to be controlled from a single master gain control. 1. SUBWOOFER GAIN 1 should be set to 0dB, in the CAL CHANNELS menu. 2. Overall system subwoofer level should be set on the BMC I/O unit connected to the AUX connector on the remote.
Dual BMC MK II I/O / Single subwoofer setup MAIN BMC Unit (1): Wire the main channels to this BMC. Subwoofer level trim, should be set to 0dB. Overall system subwoofer level should be adjusted on the AUX BMC (via remote). LFE Input: +10dB or 0dB Aux MAIN ,I N C. LFE gain can be set to either +10dB or 0dB, depending on the format. Always document all settings. Main AUX RE N TS to LFE IN blue sky internationalR RIGHT IN U A AUX BMC Unit (2): Wire all additional channels to this BMC.
