Digital connection The AVP preamplifier is equipped with six coaxial digital inputs. The digital inputs will accept either a standard PCM digital input or a digital Dolby Digital input. If you wish to use a source that has a TOSLINK output, you must convert it to coax. If you wish to use a laserdisc player that has a RF Dolby Digital output, you must convert it to digital Dolby Digital. The B & K DT-1 will do both conversions for you. To connect a digital input to the AVP, simply connect a coax cable from the digital output on your source (CD, DVD/VLD. . . etc. ) to the appropriate orange digital input on the AVP (CD, DVD/VLD. . . etc. ). In the SETUP menu, select digital on for the appropriate source, to enable the digital input (CD DIGITAL ON, VLD DIGITAL ON. . . etc. ). To connect a digital Dolby Digital (AC-3) signal (NOT RF) to the AVP, simply connect a coax cable from the Dolby Digital output on your source to the appropriate orange digital input on the AVP (normally DVD/VLD). This output MUST be a digital output and NOT RF. In the SETUP menu, select digital on or digital AC-3, to enable the digital input. The digital input will automatically switch to Dolby Digital if it is set to ON and a Dolby Digital signal is present. The AVP will default back to PCM when the Dolby Digital signal stops for more than 30 seconds. Setting the digital to AC-3 will only allow a Dolby Digital signal to be accepted. To set an input for DTS only, select DIGITAL DTS. This will only allow DTS material to be processed from the input. No advanced star operations will operate. Page 18 Surround setup Always set up and calibrate your speakers immediately after connecting your preamplifier to your system. You need to set up the speakers to achieve the best, most accurate performance from your preamplifier. This is important because the preamplifier needs to "know" your speaker configuration to control your current system. Any time you change your speaker configuration, you should perform setup and then calibration on your preamplifier. When you are setting up your speakers, your preamplifier gives you several options to help you maximize your audio/video system. Since every system is unique, you can choose from the menu options and try different combinations until the sound is exactly the way you want it.
