Here is a close-up look at the connections and adjustments available on the rear panel of the Remote Display/Control unit for the HTS-LX70.
Starting on the right side of this photo is that connection input for the control cable that comes from the Subwoofer/Amplifier.
Moving along the rear panel, to the right, there is stereo mini-jack input for portable audio devices and an iPod connection (cable supplied) for connecting an audio iPod. Lastly, on the far right is the microphone input connection (microphone supplied) for the MCACC (Multi-Channel Acoustic Calibration System). This allows the HTS-LX70 to automatically adjust the speakers according to specific room environment being used.
Lastly, across the top of the LED Control Unit rear panel are buttons for volume, input select, and on/off standby function.
