The Speakercraft MZC66 home stereo amplifier can help you use your home entertainment center to its full potential. By connecting peripheral devices such as DVD players, digital cable boxes and video game systems, you can output the audio signals of all those devices through speakers, thereby increasing the volume and sound quality that would be possible if running the devices directly through your TV's speakers.
Installation
Install the MZC66 in an area where it has at least 1 inch of clearance on either side to allow for proper venting. If the vents on the receiver do not have enough room to expel built-up heat on the inside of the MZC66, overheating may become an issue. Also, be sure to install it in an area where audio/video connection cables from all the devices in your home entertainment center can easily reach the back of the receiver. Audio/video cables that are stretched too tightly can lead to a short.
Connection
The MZC66 is equipped with numerous audio and video connection ports, making it all the more crucial to keep track of which device is connected to which port in order to save yourself confusion when trying to use the MZC66. The connections are labeled "Source 1" through "Source 5," so write down which device you are connecting to which port (i.e. "DVD player into Source 1"). Therefore, if you go to watch a DVD, you can instantly know which source the MZC66 should be set to rather than having to trace the cables from the DVD player down to the MZC66 to remind yourself.
Video Troubleshooting
If you do not see a picture when trying to use the MZC66 with a source device, check the video connection cable that attaches the MZC66 to the TV or Zone Video Display into which it is connected. The yellow video cable ports are on the top right of the MZC66 and should connect directly to the TV or display via one yellow connection cable. Secure the cable if it is loose at all; replace it if it appears frayed or damaged. If there is still no picture, the video connection cable may need to be replaced. If there is only one source device that is not giving a picture, check the yellow video connection cable that attaches the source device to the MZC66 in the same manner.
Audio Troubleshooting
A loss of audio should be addressed similarly to a loss of video, but there are two separate audio connection cables (red and white) that need to be checked. If none of the source devices give any audio output, check the speaker wire attachments that connect the six Zone speaker terminals on the back of the MZC66 to the Zone speakers. Again, any frayed, damaged or dirty speaker connection cables should be replaced at once.
