If the front panel software is not working correctly the unit will only reset if the keys are depressed during the power up sequence, WAIT UNTIL ALL THE LED's ILLUMINATE, then depress the Hard

Reset key combination.

9.4 MANUAL HARD RESET

The front panel hard reset is only possible if the front panel software is running correctly. If all else fails switch off the power, open the unit, and unplug the RAM chip (U16).This will disconnect the memory from the backup battery. Replace the RAM chip, and power up the unit.

10.0 RECORD TRACK MAPPING

Only available tracks for each machine may be mapped, the available tracks are determined by the following:-

MENU 42:- Record Tracks

0=Off 1=Alg 2=8 3=16 4=24 5=32 6=40 7=48

MENU 43:- Analogue and Video Rec Rdy

0= Disable 1= A1-A2 2= A1-A2+V 3=Asmb

The following menu may be used to determine the default settings for menu 41 for video machines

Setup | Root | Unit | Record | Menu 14:- Default Alg and Vid Rdy

The mapping of the record track arming keys is determined by the setting of menu 07 as follows:-


MENU 07:- Track Arm Keys

0= System, 1= Mcn, 2= Enabled, 3= Macro

The track arm keys have three modes of operation as follows:

0= System

The track arming keys may access any combination of tracks and machines across the system. The

Track Arming keys may be programmed individually (enter Mcn:Track followed by [Shift] followed by

[Store] followed by Track arm key) or the tracks from the currently enabled machines may be mapped across the record keys by depressing [Record] and [track arm key 1].

1= Mcn

The track arming keys follow the current selected machine. The keys are mapped automatically to the available tracks per machine as defined above.

2= Enabled

Track arming keys will follow the last selected record enabled machine. The keys are mapped automatically to the available tracks per machine as defined above.

3= Macro

Track arming keys will follow machines selected by special macro keys, Depressing one of these keys will automatically select this mode.

Macro 67 Current Selected Machine

Macro 176 System

Macro 103 Machine-A

Macro 104 Machine-B

Macro 105 Machine-C

Macro 106 Machine-D

Macro 107 Machine-E

The keys are mapped automatically to the available tracks per machine as defined above.

The action of the track arm keys is determined by Menu 8 as follows:-

MENU 08:- Record Track Arm

0= Ready, 1= Ready/Record, 2= Record

Track arming keys may operate in one of the following ways:-

0= Ready

Track arming as per multitrack, track arm keys put tracks into ready on or ready of mode. Depressing the Record key or Record & Play keys will then send the command.

1= Ready/Record

Track arming as per video machine, track arm keys put tracks into ready if the machine is not in record, if the machine is in record then the track arm keys will put the selected tracks into record.

2= Record

Track arming as per film, track arm keys will put tracks into record directly, there is no ready state. This mode should only be used in combination with track safe keys.

10.1 SR-24 Auto Track Mapping

Unlike the SR-4 that has 8 track arming keys and a bank key the SR-24 has 24 track arming keys and an optional bank key. The SR-4 is normally set so that the track arming keys follow the currently selected machine, however on the SR-24 this is less appropriate. Consider the situation with three eight track record machines, when the operator would like to track arm any of the three machines. In this situation an intelligent track-arming algorithm is necessary.

To use first select System track arming mode from the menu (Set-up | ROOT | UNIT | RECORD |

Menu 07:- Track Arm Keys 0=System).

To map the enabled machines/tracks check that the selected machine is stopped then depress

[Record] and [Track Arm Key 1] simultaneously. The tracks from machines that are connected, not in

Local, and Record enabled are mapped across the track arming keys.. If Root | Unit | Auto track Map is set to 0= One then the current selected record machine will be mapped across the system record keys, if set to 1= All Mcn the all currently record enabled machines will be mapped across the system record keys.

To restore the user EEPROM track mapping depress both [Shift] and [Track Arm Key 1]. The current

EEPROM default track mapping may be user configured. The standard is machine b tracks 1-8, machine C tracks 1-8, and machine D tracks 1-8.

10.2 Checking the current track map

The Track mapped to Record enable 1 is normally displayed in the centre position of the lower display, see section 2.07.

To check the current track map for any key depress the [Recall] key followed by the selected track arm key. The keyboard display should show:-

Mcn:Trk 00:00:02:01

Where the Seconds show the machine number (02) and the frames show the track number (01),

Track number assignment

10.3 Analog 1-4, Video, and Assemble

The SR and MR systems always provide access to the digital audio tracks. Access to the Analog, Video and Assemble tracks may be protected. There are two menu's that determine this as follows:-

Setup | Root | Unit | Rec | Menu 13:- Default Alg & Vid Rec Rdy.

Setup | Root | IFACE | Record | Menu 43:- Analog & Video Rec Rdy.

Menu 13 (Default menu) will determine the default setting when new machines are connected, Menu 43 will set the current setting. See sections 7.14 and 7.42 for full information on this.

Provide that menu 43 is not set to disabled it is possible to access the analog and video track arming keys by using the Bank key, auto-map (9.01) or setting individual keys. The default key are defined as follows:-

Video

Track 5

Assemble

Track 6

Crash Record Enable Track 8.

The Middle of the lower line in the display will display available tracks as follows

A1-A2

A1+A2+V

AV+ASMB


10.4 Special ADR Keys

When an ADR keyboard is specified two extra keys are normally fitted as follows

INDIV

Record track keys are interlocked so that Enabling one track disables the others

FINAL

When Final is enabled the user may specify one or more tracks not to be interlocked

For Example the operator wishes to record multiple takes on different tracks but wishes to keep the final selected take on track 8.

1) Enable FINAL and select track 8 only as the final track

2) Deselect FINAL and the select Track 8 as record enabled

3) Select INDIV so as to make other tracks auto cancel.

4) On the first pass enable track 1, Track 8 will remain enabled

5) On the second pass enable track 2, Track 8 will remain enabled but track 1 will be cancelled

6) On the third pass enable track 3, Track 8 will remain record enabled track 2 will cancel.

7) On the forth pas disable track 3, Track 8 will remain record enabled

10.5 SR-24 Custom Mapping

The factory default system track mapping on the SR-24 is as follows:-

SR-24 tracks 1..8

Machine B tracks 1..8

SR-24 tracks 9-16

SR-24 tracks 17-24

Machine C tracks 1..8

Machine D tracks 1..8

This may be set to a user specification, first set the track mapping as desired, then use

Set-up | Root | Unit | Generic | Menu 30:- Macro Protection 4= Write User

exit setup and the desired setup will be written to the EEPROM.

10.6 Track Mapping Keys

If required the following keys/macros may be used to change the mapping of the Track Arm Keys as follows:-

Bank

Change either system or machine Track Arm Bank (Macro-65)

The following keys change the settings of Setup|Root|Unit|Record|Menu 07:-Track Arm Keys.

Macro 87 Follow Mcn Follow Selected Machine.

Macro 88 Follow Rec Mcn Follow Record Machine.

An Example using three keys to control the track mapping over 24 track arm keys in a 6 machine MR system.

Key1:McnMap1 Used to select Machine D tracks 1-24 Machine 'D' is specified in the Custom Factory

Setup but may be changed to any Port by selecting the port required then use

[Shift] followed by the [McnMap] key. The track mapping may be started at any combination of machine and track by entering the desired machine and track and using [Shift] followed by [Store] followed by the [McnMap] key

Key2:Custom1 Track Arm keys 1..8

= Machine C (MFX-48) tracks 1..8

Track Arm keys 9..16

= Machine E (DA-98) tracks 1..8

Track Arm keys 17..20 = Machine B (Digi-Beta) Tracks 1..4

Track Arm key 24 = Machine F (PCM7030 DAT) Analog 1&2

The custom track mapping is set in the Custom Factory setup, it may be changed for each individual track arm key.

Key3: Follow Enable

The keys for this example are labelled as follows:-


11.0 VARI-SPEED

The Varispeed Option enables the user to control and chase machines whilst in vari-speed. This option is normally used for Audio and not audio visual productions.

When Varispeed is enabled the system is no longer locked to video but to an internal crystal oscillator.

The Timecode generator becomes the timing master for the system. If Varispeed wordclock is required the Generator output should be connected to a suitable wordclock generator (Nanosyncs, Time

Machine, A&D Master Clock) and used to generate a wordclock reference for the studio.

When using the system with Sony protocol machines that lock to timecode they must be run as slaves or the generator should be selected as the master when in play as follows:-

Setup | Root | unit | Chase | Menu 21:- Master in Play

11.1 Varispeed Macro keys

3 Varispeed Macro keys are provided as follows:-

[Varispeed]:

[Dec Varispeed]:

[Inc Varispeed]:

Macro 96 See below for use

Macro 203 Decrement varispeed in 0.1% steps

Macro 204 Increment varispeed in 0.1% steps

Varispeed Enable/Disable:

[Shift] followed by [Varispeed]

Set Vari-speed: The varispeed may be set in 0:10% increments from 88:00% to 112:00% by first entering the required varispeed via the keyboard and then using [Store] followed by [Varispeed].

Trim Varispeed: Varispeed may also be adjusted by entering the amount to adjust and using the

[Trim +] or [Trim -] key followed by [Varispeed].

Examples:

To set a varispeed value of +1.5% enter 00:00:01:50 then [Store] followed by [Varispeed]

To Set a varispeed of -1.5% (98.5%) enter 00:00:98:50 then [Store] followed by

To Set a varispeed of -1.5% alternative method using trim keys, first reset varispeed to 100% by using [Clear] followed by [Store] followed by [Varispeed]. Enter 00:00:01:50 then [Trim -] followed by [Varispeed].

11.2 Lynx operation in varispeed mode

The once modified the SR/MR/RM system provides the frame rate signals to the lynx module in both normal and varispeed modes.

When in normal/varispeed mode the lynx will resolve the controlled machine wen in normal play as a

Master or Free machine. The Varispeed setting may therefor be use to varispeed a single machine controlled by the lynx.

Note we currently have to modify the lynx as described in section 10.03.

11.3 Timeline Lynx Modification (Mark I)

There is no current support for lynx available and we have been unable to determine the serial command controlling the reference source (if there is one). We have therefore to disable this in hardware as follows:-

Link U50 pins 4 & 5 or Q2 base to Q2 emitter
