To proceed, you will first determine where your primary listening viewing seating position will be. Next
you will want to measure the distance from the primary listening/viewing position each speaker using
a tape measure. Your measurements need to be accurate to within 1 foot. Use can use the accompa-
nying blank chart to fill in your speaker distances. Once you have filled in the speaker distances on
the second line, take the highest value distance and insert it into the top row of each speaker column.
Then subtract the distance of the speaker from the distance of the Reference Speaker. The end value
(in feet) is the distance value for the delay setting for that speaker.
With the distance information collected, you can now proceed to calibrate the Cinema Reference
Mach II using the steps below. The Cinema Reference Mach II’s Out of the Box delay settings have all
delays set to 0 Feet.
Please note, at least one channel needs to remain at a delay setting of 0 Feet. If you apply a
delay distance to each channel, you will cause the Cinema Reference’s DSP to loose the delay
reference point. It is extremely important that at least one delay distance point remain at 0.
1 Turn the Mode knob clockwise until the display’s second line reads SETUP MENU and then
press the Mode knob.
2 Turn the Mode knob clockwise until the display’s second line reads PRO SETUP and then
press the Mode knob.
3 Turn the Mode knob clockwise until the display’s second line reads STEP 3 DELAY and press
the Mode knob.
4 The display will indicate DELAY LEFT. If the left channel is the at the furthest distance from the
seating area, you will not need to delay this channel. To proceed to delay other channels,
turn the Mode knob to the next channel you need to adjust and proceed with the steps
below. To return to the previous setup menu level, turn the Mode knob clockwise until the
display’s second line reads BACK TO MAIN and press the Mode knob. To completely exit
the setup mode at any time, turn the Volume knob.
5 When the display’s second line displays a channel whose delay you need to set, press the
Mode knob.
6 Turn the Mode knob to the appropriate delay distance noted in Feet. When completed, press
the Mode knob.
7 Turn the Mode knob to the next channel requiring a delay setting and press the Mode knob.
8 Repeat steps 6 and 7 until all channel delays have been appropriately set. Remember to
leave the speaker at the greatest distance from the listening area to a delay setting of 0
Feet. When completed, turn the Volume knob to exit the setup mode.
