Welcome to the TASCAM SX-1LE
The TASCAM SX-1LE is a special edition of the renowned SX-1 Digital Production Environment. This document is designed to explain the differences between the two models and how you can upgrade your SX-1LE to get the SX-1 features you might need later on.

Optional Features

The following features of the SX-1 have been omitted from the SX-1LE. See below for information on adding these features to your SX-1LE. Fast/Wide SCSI Port: The SX-1LE uses IDE for its internal hard drive and CD-RW drive. Unlike the SX-1, there is no SCSI port available for adding external drives. 512MB of memory: The SX-1LEs memory is 256MB, allowing waveform display of projects up to 720 track minutes (thats 45 minutes of 16 tracks.) Less tracks equals longer recording time with waveform display (90 minutes at 8 tracks, etc.) RS-422 Control: The SX-1 is capable of interfacing with other equipment using the RS-422 (Sony P2) protocol. Video Sync Input: The video sync input of the SX-1 allows it to lock with frame resolve to a video reference such as a house video blackburst generator. LTC Output: The SX-1 has an LTC output port to send SMPTE timecode to devices for synchronization. The SX-1LE still has an LTC input port, so it can chase SMPTE, but no output port. Antares Mic and Speaker Modeling plug-ins: These flexible modeling plug-ins are not included in the SX-1LE. TC Works SX-1 Reverb: This plug-in has been replaced by the versatile new TASCAM Reverb plug-in, with 26 all-new presets.

Ordering Information

To order the above optional features in the USA: If you wish to add any or all of the above features to your SX-1LE, contact your TASCAM dealer and ask them to order the above upgrade kit from TASCAM.

Documentation

The SX-1LE comes with the same documentation as the SX-1, including the updates for the version 1.50 operating system update. Disregard any of the instructions that mention the optional features listed on page one if they have not been installed. The user interface of the SX-1LE is identical to the SX-1, with the exception of the Video Clock indicator on the front panel.

Compatibility

Projects created on an SX-1 with any OS (version 1.00, 1.10 or 1.50) can be used on the SX-1LE and vice-versa. Projects can be shared between one SX-1 and another using the Project Backup to CD function. Projects saved using SX-1 version 1.50 cannot be opened by devices running SX-1 version 1.00 or 1.10. Contact TASCAM for a software update to version 1.50. If a project is loaded that calls for an effect not loaded on that machine, the plug-in effects will show up as empty effects slots. When the session is saved and reopened on the original machine, the effects slots will still appear as empty slots.

SX-1 Version 1.50 Sony P2 Protocol Documentation
This manual describes the changes and additions to the Sony P2 support for the SX-1OS V1.50 software. See also the V1.10 release note for other issues that were addressed after V1.00

Additions:

P2 Master reads and uses Rec-arm tally messages. In V1.00 and V1.10, the SX-1 does not send out requests for EDIT PRESET STATUS, or use the information in the status map that indicates Rec-arm status. Without this, the SX-1 will ignore audio track arming that occurs at the remote machine, and the front panel channel REC buttons will not light. Only actions from the SX-1 itself would work. In V1.50, the SX-1 continually follows the status of the external machine and updates its internal maps and channel REC button LEDS accordingly. This allows a higher level of confidence when the controlled device is out of sight away in a machine closet or room. REC=4 devices now can choose digital or analog track mapping. In V1.00 and V1.10, remote devices that had RECS=4 specified would use the ANALOG rec-arm bits in the P2 protocol. Thus for devices that had 4 digital tracks, it was necessary to choose recs=8 and ignore the assigned buttons for 5 thru 8. Some devices would map these bits to Timecode tracks and other functions that the user would prefer not to have affected. In V1.50 the choices have been expanded: 2A 2D 4A 2 Track using A1 and A2 Analog assignments 2 Track using D1 and D2 digital track assignments 4 Track using A1 A2 A3 A4 analog assignments. Most 2 Track analog devices map the timecode track to A3 and have nothing in A4. 4D -4 Track using D1 D2 D3 D4 digital assignments. 8 Track using D1 D8 digital assignments 16 Track using D1 D16 digital assignments. 24 Track using D1 D24 digital assignments. 32 Track using D1 D32 digital assignments. No Rec Arm assignments.
Rec arms now disabled when in Mixdown mode From V1.50, when the SX-1 goes into Mixdown mode, any tracks Rec-armed over P2 will be turned off until MixDown mode is exited. This is for safety and to make the behavior similar to the SX-1s internal recorder. If the resulting mix is to be recorded to the external P2 device, another pass is required after
exiting MixDown and loading the MixDown takes. P2 Slave support. V1.50 adds the ability to control the SX-1 from an external device using the P2 protocol. This is a large feature, and is fully described below.

P2 Slave

The SX-1 can re-use the RS422 port for P2 Master or P2 Slave. To set up P2 Slave, use the LCD Transport / Machine Control List page. First make sure there is no P2 Master or other RS422 device already in the list. If so, use the DELETE LAST menu until there is no 422 entry in the list. Select ADD, select RS422 in the submenu and turn the 4th encoder until P2 SLAVE is highlighted in the menu. Press OK Make sure that the SX-1 HDR entry has CHASE=LTC Master set. It is still possible to control the SX-1 if it is set to chase LTC or MTC, in which case motion control commands will be translated and sent to the designated timecode master, if one is in the machine control list, and just EDIT ON/OFF & Arming commands will be available. Note: The RS422 port on the SX-1 is pre-wired to be a Master (Controlling Device). When using the SX-1 as a P2 Slave, it is necessary to provide a cross-over connection to make the SX-1 look like a Controlled Device. RS-422 Controller to Controller Cable (crossover cable) 9 pin D-sub male Tx+ TxRx+ Rxshell 3 ------------- / twisted 8 ------------- / 2 ------------- / ------------pair pair shield 7 ------------- / twisted 9 pin D-sub male -----------------------------Rx+ RxTx+ Txshell
The physical and electrical characteristics of the RS422 port are otherwise identical to the
Sony P2 Specifications. Timing: The SX-1 will reply to incoming commands within 9ms. The time required to actually execute the command and update the STATUS MAP will vary and may be much longer. See note *6 for details about deferred commands. Lists of supported commands:

Notes:
*1 Command is acknowledged, but no action is taken. *2 The SX-1 can selectively reply to this command, set in the LCD Preferences screen, TRANSPORT page. F01A 6003 101C TASCAM HDR Series (Default) Sony 3324S Sony BVU950
This reply data is also affected by the Frame Rate setting of the currently loaded project.
At 25 Frame (PAL/SECAM), the value 0100 is added to the reply data.

(F01A->F11A, etc)

At 24 Frame (FILM), the value 0200 is added to the reply data. (101C->121C etc) All other frame rates have no effect on the reply data, e.g. 29.97 and 30 frame rates, drop or non-drop. *3 If the SX-1 is currently set to emulate the Sony BVU950, the REC command is treated the same as EDIT ON (20 64), and the HDR will punch in on rec-armed tracks. Otherwise this command is acknowledged but ignored. See also Note 6. *4 Speed related commands. The SX-1 supports both single byte and double byte versions of the standard P2 speed command. Single data byte: Calculated speed = 10

N 2 32

where N is the value of the data byte.
For a double data byte command, the 2nd data byte is used as a fraction M/256 to linearly interpolate between the calculated speeds for (1st data byte=N) and (1st data byte= N+1), where N is the first data byte and M is the second data byte. If the 1st data byte (N) is zero, the actual speed is 0.0 (Stop), instead of the 1/100 speed as expected by the above calculation. This is in accordance with many other manufacturers implementations. The resolution of the actual speed is 1/1024 normal speed, minimum = 1/1024, maximum is 1536/1024 (1.5x normal play speed). Any speed request greater than 1.5x is treated the same as a request for 1.5x speed. The SX-1 will smoothly ramp between the current playing speed and the newly specified speed, updating the current play speed every 1024 samples (21.3ms at 48KHz). Audio is reproduced at all supported speed rates.

*6 Deferred commands. These commands will execute on a frame or half frame boundary, a specified number of frame edges after the command was first received. This allows an edit controller to set-up punch in/out events accurately with respect to the recorded audio. If the transport is not moving at the time the command is received, then no defer calculation is performed, and the command is executed immediately. Two SX-1 preferences affect the calculation of the timing. a) P2 Punch Delay: This may be set to OFF, 1 frame or 2-6 frames. When set to OFF, the SX-1 does not align the execution of the received command with any frame edge, but will execute the command as soon as it is parsed. When set between 1 and 6 frames, the SX-1 will execute the command on the frame edge that is the specified number of frames after the frame in which the command was first received. b) P2 EDIT FIELD: If the SX-1 is also receiving a valid VIDEO or TTL signal at the VIDEO SYNC IN port, this control can be used to specify which field of the frame that the command will be executed in. This setting may be over-ridden temporarily using the EDIT FIELD 41 3A command. The SX-1 does not need to be set to Master Clock=VIDEO for this function to work. EDIT FIELD = AUTO: received in. EDIT FIELD = FIELD 1: The command will always be executed in the first field, regardless of whether the command was received in field 1 or field 2 EDIT FIELD = FIELD 2: The command will always be executed in the second field, regardless of whether the command was received in field 1 or field 2. If the P2 Punch Delay is set to OFF, this parameter has no effect, and cannot be edited from the LCD. The command will be executed in the same field that it was

If there is no valid VIDEO or TTL signal being received by the SX-1, then the command will be executed during field 1 of the calculated frame. The frame boundaries are assumed to line-up with the first sample at 00:00:00:00 If another command (deferred or not) is received while there is a command pending, then the pending command is executed straight away, and the next incoming command is processed. If the new command is also deferred, it will be marked for pending execution. If the transport stops moving while there is a command pending, the command is executed immediately. When the EDIT ON command is received, the SX-1 Auto-punch Rehearsal function is automatically turned off, and the HDR performs a punch in record. When the SELECT EE ON command is received, the SX-1 Auto-punch Rehearsal function is turned on, and the HDR simulates a punch-in record. When the EDIT OFF command is received when the SX-1 is recording, the SX-1 will punch out of record. *7 SYNC PLAY: The SX-1 will ignore the data supplied in the command and will just start playing. Frame settings must be made using the Clock and Video resolve modes separate from the P2 Slave. *8 PROGRAM PLAY: This does not imply any video or frame resolution, it is just a different way of specifying the shuttle speed. Calculated speed = N /10 percent of play speed, where N is the first data byte. For PROGRAM PLAY FAST, this calculated speed is added to normal speed, i.e. the range of control is 1x (DATA=0) to 1x plus 25.5% (DATA=FF) = 1.255x For PROGRAM PLAY SLOW, the range is 1x (DATA=0) to 1x minus 25.5% (DATA=FF) = 0.745x As in note *5, the actual resolution of the SX-1 playback is 1/1024 normal play speed, and the current play back speed smoothly ramps between the current speed and the requested speed, updating every 1024 samples.
*9 DMC SET: The SX-1 does not support Dynamic Motion Control, but it recognizes the DMC SET FWD and DMC SET REV commands. The SX-1 will treat them the same as VAR FWD and VAR REV with a single byte data representing SPEED. This is to support some remote control devices that use these commands for rough JOG and SHUTTLE control. The specified speed is memorized, and the DMC START command will then initiate a VAR FWD or VAR REV with this memorized speed. This behavior is copied from the Tascam DA-98 and DA-98HR DTRS machines. *10 FULL EE MODE. When received, the SX-1 will turn all of the HDR record tracks input monitor parameters to ON or OFF as requested. If some of the input monitors were previously set, they will be over-ridden by this command. If a HDR track is currently recording (its REC ARM is lit and the transport is recording), then the input monitor is automatically on, and a request for FULL EE OFF will be ignored. *11 EDIT PRESET Depending on the selected P2 Slave Device Type (emulated machine), the SX-1s response to the edit preset command will change. If the Device Type is set to TASCAM or Sony 3324S, then only the digital track assignments are used. If the Device Type is set to Sony BVU-950, then only A1 and A2 are used, and these are always mapped to HDR tracks 1 and 2.

IF DATA1 BIT 6 (INS) is 0, all data is assumed to be zero. If the SX-1 is currently in MixDown mode, all data from this command is ignored. DATA1 BITs 5,4,2 have no effect. If the device type = BVU-950, A1 and A2 are read and applied to HDR Channel 1 and 2, CH1-CH16 bits are ignored. HDR tracks 3-16 that are currently in record will not be cleared. If the device type = TASCAM or SONY 3324S then A1 and A2 status is ignored and the bits CH1-CH16 are read and applied to HDR Channel 1 to 16. If the EDIT PRESET command has less than 3 data bytes, the data for the unspecified
tracks is assumed to be 0. If there is no audio take currently assigned to an HDR destination channel that is requested to be in EDIT mode (bit = 1), then the request for that channel is ignored. The ASMBL, VIDEO and TC bits in data 0 are always ignored. This command is a deferred command whose execution may be delayed to occur on a subsequent frame or video field boundary, see Note *5 for details. *12 NAK DATA: The SX-1 returns the data value 01 = UNDEFINED COMMAND for commands that it does not recognize. If the received command has an incorrect checksum, the data value is 04 = CHECKSUM ERROR. This is usually attributed to signal quality loss due to the use of inferior or un-shielded cables or too long of a cable run between the SX-1 and the controlling device. *13 Status Map

If more than 3 data bytes are requested, data bytes above DATA 2 will contain zero. *15 CURRENT TIME SENSE: The SX-1 will reply to all requests for time data with the same data, i.e. the current timecode. Requests for the TIMER values will return the same data, and the TIMER cannot be reset to zero, although the PRESET TIMER command will be acknowledged and ignored. Requests for the User Bits Data (UB) will return zeroes. The format of the sense data byte is as follows.

RS-422 9-Pin D-Sub connector
The SX-1 RS-422 connector (9-pin D-Sub female) has limited clearance to the bank panel, so in some cases, a cable may not fully mate with the SX-1, making connection unreliable, or the locking screws may not attach correctly. To fix this problem: Add washers under the SX-1 DSUB connector's nuts (1 or 2 as required) so that the cable's screws can reach the SX-1 connector. The appropriate washer is designed for DSUB: Part number 92603306-00 :D-SUB WASHER HW-C050MN00) A regular M3 washer cannot be used.
