The ASP510 provides a number of solutions for preparing 5.1 and Dolby Digital masters. The schematic shown assumes that both 5.1 and Dolby Digital are to be created simultaneously.
The 5.1 mix from the console is connected to the ASP510 via its SURROUND BUS port with the 5.1 recorder interfaced via the SURROUND A RECORD and PLAY ports, monitoring is via the SURROUND A RECORD AND PLAY monitor source selection switches.
Dolby Digital encoders and decoders are connected to the ASP510 SURROUND B RECORD AND PLAY connectors (via suitable convertors depending on the type of codecs being used). The encoded output is then recorded on two track machine C with the machine output connected to the decoder input and thereby to the ASP510.
The direct and recorded 5.1 mix can now be monitored by using SURROUND A PLAY and RECORD monitor selection switches. Selecting SURROUND B PLAYas the monitor source enables the decoded output to be monitored before and after tape (record/playback switching is performed by the recorder).
The two track machines may be used to record either the Stereo mix from the console or a stereo downmix of the 5.1 mix by selecting BUS or DOWNMIX respectively as the STEREO RECORD SOURCE.
If a recording of the Dolby Digital encoded 5.1 mix is not required the encoder and decoder may be looped together and connected to the ASP510 ENCODER and DECODER ports. The codecs can then be inserted into the monitor chain by depressing the ENCODER/DECODER switch.
Compatibility checks are possible at all times using the MONITOR FORMAT selection switches.
