7. C90 22 5 minutes C60 15 minutes C46 11 5 minutes Recording Format Although the MT8XII uses the same type of cassettes as those used with normal cassette record ers MT8XII tapes are not compatible with normal cassette players A normal cassette recorder uses only two tracks 1 left and right stereo channels and both tracks are recorded simulta neously The MT8XII on the other hand can record eight tracks on a standard audio cassette Even more importantly you can record and playback these tracks individually You can record up to four tracks simultaneously or one at a time a technique called overdub recording Another major difference is that the MT8XII uses only one side of the cassette There is no B side If you turn over an MT8XII cassette you ll hear the tracks play backwards This is because the MT8XII uses the full width of the tape to record eight tracks The tape speed is also different Normal cassette recorders run at 4 8 cm second Whereas the MT8XII runs at 9 5 cm second providing greater sonic performance About dbx Noise Reduction The MT8XII uses the dbx noise reduction system to reduce tape hiss and keep your recordings clean and crisp For the best performance it s recommended that you use the dbx noise reduc tion for all your recordings You should always use the dbx noise reduction system to play back tapes that were recorded with the dbx system on MTS8XII Maintenance The MT8XII req

12. GROUP These switches select the Group buses as the monitor source This allows you to monitor signals that are assigned from input channels or ST inputs to groups for recording Use these switches to monitor what will be recorded For example if you re recording the sounds from three input channels to one track simultaneously you ll need to listen to a mix of the three sounds in order to balance the levels correctly You can do this using the GROUP switches When only the 1 3 or 2 4 MONITOR SELECT GROUP switch is pressed the monitor sig nalis set as mono This ensures that the signal being monitored appears in both the left and right monitor speakers So even when you monitor a single group signal it will be heard through both speakers When both the 1 3 and 2 4 MONITOR SELECT GROUP switches are pressed however the monitor signal is set as stereo So you can monitor stereo signals on Groups 1 and 2 or Groups 3 and 4 STEREO This switch selects the Stereo bus as the monitor source This allows you to monitor the STEREO OUT signals and is typically used during mixdown It can also be used to monitor signals that are not going to be recorded by the MT8XII such as a MIDI tone generator that is controlled by a MIDI sequencer In this case the tone generator is only monitored while other sounds are recorded on the MT8XII Then for the final mixdown the tone generator sounds are mixed with the sounds recorded on the MT8XII and mixed down
13. In this system a SMPTE MIDI converter is used to generate the SMPTE timecode that is recorded onto Track 8 of the MT8XII It has a MIDI merge function that merges the MIDI Clock information derived from the SMPTE timecode with the MIDI performance data from the syn thesizer Some MIDI interfaces have two MIDI In jacks In this case the merge function is per formed by the MIDI interface or MIDI sequencer The MIDI sequencer is shown with two MIDI OUT jacks So if you have only one MIDI OUT jack connect it to the SMPTE MIDI converter when striping the tape then to the synthesizer for subsequent operations Synthesizer MIDI IN THRU Drum machine MIDI IN 96908 SMPTE IN SMPTE OUT SMPTE MIDI Converter MIDI IN MIDI IN Computer amp MIDI sequencer software MIDI IN MIDI OUT 2 MIDI OUT 1 MT8XII Owner s Manual Striping the Tape 43 Striping the Tape 1 Connect the MT8XII to the SMPTE timecode generator FSK MIDI verter as shown in the previous section If you are using FSK press the SYNC button once If you are using SMPTE timecode press the SYNC button twice The SYNC indicator lights up for FSK operation or flashes for SMPTE timecode operation It s important that you set the MT8XII to work with the SYNC signal format that you are using and use the same setting for synchro
14. MT8XII amp MIDI MIDI sequencers and MIDI controlled musical instruments have become essential tools for modern recording It s common these days not to record MIDI instruments to tape until the final mixdown This has the benefit of freeing up tracks for acoustic sounds and reduces the need for recorders with many tracks The MT8XII is ideal for recording vocal guitar and other acous tic sounds and can easily be integrated into a MIDI system Using the MT8XII in a MIDI System To use the MT8XII in a synchronized MIDI system you must record a SYNC signal onto Track 8 of the MT8XII before recording anything else This is called striping the tape and it only needs to be done once During playback the SYNC signal is output from the MT8XII and sent to MIDI sequencer The MIDI sequencer reads the SYNC signal and plays back in synchronization with the MT8XII When the MT8XII is stopped the MIDI sequencer stops too In this way the works as the master control device in a synchronized MIDI system You still use the transport controls on the MIDI sequencer but only the MIDI sequencer will respond The SYNC signal is recorded and played back on Track 8 of the MT8XIL so you cannot use this track for recording You can however still use Input Channel 8 as an input channel Although it s best to keep the FLIP switch on channel 8 in the up position and the CUE LEVEL control turned down Otherwise you will be able to hear the S
