Step 1 "BASS MANAGER - ON"- Press SELECT three times, or until the display reads "SETUP MENU". Press the UP or DOWN ARROW keys until the display reads "BASS MANAGER - ON". If the display reads "BASS MANAGER - OFF", press YES To turn it on. STEP 2 "MUTE THE SUBWOOFER" - Press the SELECT once, or until the display reads "MUTE CHANNELS". Press the UP or DOWN ARROW until you get to the subwoofer channel and then press YES . STEP 3 "FINDING YOUR REFERENCE LEVEL" - Turn the gain on the remote to -50dB. Patch a pink noise generator, tape or other source with at least 60 seconds of 0dBVU Pink Noise into your console or workstation. If you are using a digital source, the test signal should measure -20dB FS (0dB FS = Full Scale Digital). Confirm that all your speakers are turned on and that the gain on each speaker is set to a moderate level. Slowly bring up the gain with the master Volume Control knob on the BMC | Remote until you measure 85dB on the C scale, with the response set to Slow. Measure SPL exactly at the reference mix position, with the SPL meter at arms length, the microphone at seated ear height, angled at approximately 45 degrees, and pointed at the center speaker. If you are using a 1/3 octave RTA, align the level of the speakers to 70dB reference line on the analyzer. Note the gain displayed on the remote when the center channel is at 85dBc.
