TCR Series User's Manual

`Introduction 1-1

Introducing the TCR Production Recorders

In the realm of audio recording, 360 Systems’ family of synchronous audio recorders represents a “next generation” technical development. Moving beyond “tapeless,” the TCR series couples an entirely new machine architecture with the feature set most requested by industry professionals.

The TCR4 and TCR8 are production recorders, designed specifically for television broadcast, video production and professional audio recording. As professional grade machines, they deliver premium quality audio and precise time code synchronization in a robust, carefully engineered package.

∙Speed and Versatility

The TCR’s design introduces speed and versatility to a variety of audio tasks. TCR recorders are not just “playout” machines for dubbing — they include many production features such as auto-locate, seamless punch-in, read-modify-write (RMW), looping, editing and offsets — features that make the TCR a first choice as the primary studio recorder.

∙24-bit Performance

To deliver the 24-bit performance expected of a new generation product, 360 Systems has designed entirely new “ultra-low jitter” clock generation circuits. In addition to professional analog and digital input circuitry, XLR connectors are provided as standard.

∙A Versatile Platform

With the industry in transition in regard to file formats and media, the TCR is built to accept many kinds of media and play many types of files. Using TCR, files will be able to be directly transferred to and from leading workstations, on media of the user’s choice.

Choice of TCR Models

360 Systems offers two TCR models, each designed for different audio production requirements.

∙Model TCR8 Eight Track Recorder

The TCR8 is designed for synchronous recording and playback in video, television production, cinema sound and broadcast applications. The TCR8 is also the ideal choice for surround-sound production, handling six channels (5.1) plus Lt-Rt. As a fast non-linear recorder, TCR8 is a natural upgrade from tape, and provides easy file interchange with popular workstations.

As your primary studio and mastering machine, TCR8 functions in standalone mode or, in the future, it can be combined with up to seven other recorders for transparent 64-track operation using the TCR’s multi-machine sync bus. Time code gives the TCR8 unprecedented editing power, including automated punch-in punch-out capability with variable length crossfade and Undo. Best of all, and unlike any other system, the TCR8 can record an entire working day of 24-bit audio — without reloading media.

∙Model TCR4 Four Track Recorder

The TCR4 precisely answers the need for a machine to replace time code DAT and “audioonly” VTRs. It includes the third and fourth tracks so often needed in video production, and provides greatly improved audio quality, cost-effective removable media and the instant response of a hard-disk recorder. Most important, TCR4 delivers a degree of reliability unattainable with tape-based systems.

Note that recorded files and sync connections are compatible between the TCR4 and TCR8.

TCR Series User's Manual

Product Highlights

This section outlines many of the superb features designed into the TCR series of digital multi-track recorders. All of these features apply to both the TCR4 and TCR8.

∙Unlimited Storage

Today’s projects result in very large audio files, particularly when they are multi-track, 24bit, or recorded at high sample rates. With the advent of affordable very high capacity drives, the file size limitation has been removed. TCR can accept an internal hard disk of unlimited size, with individual file size extending to the 24-hour limit of SMPTE/EBU time code.

∙High Density Removable Media

TCR recorders include a 250 MB Zip® drive as standard equipment. Each 250 MB Zip® cartridge provides a half-hour of low-cost file storage. Additionally, a 5_" drive bay accepts many user-selected drives, including removable hard disks, magneto-optical disks, and the emerging ultra-high density cartridges. A rear-panel SCSI port connects as many as five additional drives to the TCR system.

∙Programmable Hardware

360 Systems brings an entirely new design concept to the TCR platform — Programmable Hardware. To allow the system to be reconfigured as needs arise, much of TCR’s internal architecture is built with programmable Flex® logic, which can be reconfigured under software control. Using the built-in Zip drive, new hardware and software tools can be loaded. Overall, this superb capability means that TCR can be upgraded, modified and reconfigured with minimal disruption to your schedule.

∙Word Size Flexibility

As top quality audio becomes an increasing priority in the entertainment industry, 360 Systems selected 24-bits as the standard word size for all TCR recordings. However, optional 16 and 20-bit digital outputs can be generated for compatibility with older equipment.

∙Control Panel Clarity

The TCR’s control panel is designed for ease-of-use, with features specifically tailored for audio and video professionals. The large illuminated LCD screen provides clear and concise data for each system mode, including file names, machine status, edit operations, task prompts and operator “alerts.” A separate large LED readout is provided for clarity in reading time code position. For metering, a precise 14-segment LED meter array shows each channel’s level. For further operator comfort, intuitive VTR-like controls including the familiar Jog/Shuttle Wheel are provided.

∙Time Code Synchronization

TCR recorders include a complete set of SMPTE-EBU time code capabilities. They can lock to all common NTSC and PAL sync formats, including VITC, LTC, word clock, AES/EBU, internal crystals, or the multi-machine bus. Sample and playback rates can incorporate a ±0.1% pull-up or pull-down to accommodate any format conversion.

TCR Series User's Manual

`Introduction 1-3

∙Standard Editing Functions

The TCR series includes a standard array of editing functions, including Cut, Copy, Insert, Paste, Erase and time offsets for individual tracks and for the entire machine. The convenient Jog Wheel, interactive LCD screen and track markers all combine to make editing easy. In addition, there’s an UNDO button for quickly correcting mistakes.

∙Remote Control Capability

All TCR recorders include a 9-pin serial port for seamless interfacing with edit controllers — just like a VTR. Using standard RS-422 VTR control protocol, the TCR provides the instant response of a non-linear recorder when used in a multi-machine editing configuration. TCR can emulate several common types of VTR and Time Code DAT transports.

TCR Options

TCR recorders may be configured with a choice of high-capacity drives for both the internal drive and the optional drive in the Drive Bay.

The following table lists recording times for each size drive including the standard 250 MB Zip® drive, in various multi-track recording modes. The recording times listed are approximate, and are based on continuous recording of all tracks simultaneously. Use of fewer tracks, or intermittent audio, will yield an increase in the available storage time.

Calculated TCR4 and TCR8 Recording Times at 48kHz Sample Rate

Track Count	250 MB	9 GB	18 GB	36 GB	50 GB
	Zip Disk	Hard Disk	Hard Disk	Hard Disk	Hard Disk
Eight Track Recording	3 min. 20 sec	2 hr 10 min.	4 hr 20 min.	8 hr 40 min.	12 hr 3 min.
Four Track Recording	6 min. 52 sec	4 hr 20 min.	8 hr 40 min.	17 hr 21 min.	24 hr 6 min.
Two Track Recording	14 min. 10 sec	8 hr 40 min.	17 hr 21 min.	34 hr 43 min.	48 hr 13 min.
Single Track (mono)	28 min. 20 sec	17 hr 20 min.	34 hr 42 min.	69 hr 26 min.	96 hr 26 min.

Important The Drive Bay assembly, including the drawer, drive and associated connectors, is an optional item that should be pre-configured at 360 Systems’ factory. If you wish to upgrade your system to include an optional drive for the Drive Bay, please contact 360 Systems Customer Support at the location listed in the front of this manual. Only qualified service personnel should perform the upgrade procedure.

LED VU Meters

Fourteen LEDs display the recording level, covering a range from +20 dB to –70 dB. The headroom displayed between the “zero” reference and “clip” level can be programmed to conform to the common standards of 16 dB and 20 dB.

The CLIP LED lights when the input level for the associated track has peaked. It remains on until STOP, PLAY, ARM or MON is pressed.

The SLIP LED below the level display lights when that track has been offset in time with respect to others.

Track Arm Buttons

Eight numbered track ARM buttons are provided on the TCR8 — four on the TCR4. When lit RED, the selected tracks are armed for recording.

Monitor Buttons

Eight MON (monitor) buttons are provided on the TCR8 — four on the TCR4.

When MON is toggled on (RED) that channel’s input will be passed through to the output. When MON is toggled off, that channel’s output will be from disk.

Time Code Display

The Time Code Display provides several kinds of information, depending on the operating mode of the recorder. The display can present external time code, time code with offset, or the output of the internal time code generator.

TC LOCK

EXT SYNC

Two status LEDs are also provided in this section:

∙TC Lock — the TC LOCK LED lights whenever the TCR is locked to incoming time code, either LTC or VITC.

∙External Sync — the EXT SYNC LED lights whenever the TCR is referenced to an external sample rate. When this LED is off, the TCR is running on its internal sample rate reference.

2-4 Overview

TCR Series User's Manual

Many buttons have both large and small legends. These are dual-function — the key’s function depends on the context of the current operation. It is not necessary to use a “shift” key for the second command.

Capture / Mark

The CAPTURE button “grabs” a time code for use on the Transport Screen. When pressed, the value in the red Time Code Display is transferred to the Time Code Register on the Main display.

The MARK button places a checkmark (ü) after a filename on the File List. The marks are used to group files together for functions such as copy and erase.

Locate / Find

The LOCATE button instantly “cues” to the time code value shown in the Time Code Register.

The FIND button allows you to quickly find files. When pressed, the name of the desired file can be entered, and the file immediately retrieved.

Store / Page Up

The STORE button will store the time code value that currently appears in the Time Code Register, in a “Location Register”, so it may be retrieved for future use.

The PG UP (page up) button pages upward when a list is longer than the screen.

Recall / Page Down

The RECALL button allows you to recall a time code value from a Location Register, and place it in the Time Code Register.

The PG DN (page down) button pages downward when a list is longer than the screen.

Keypad / Alpha

TheKeypad is designed for both numeric and alphanumeric entry modes, depending upon the current operating context.

∙The KEYPAD buttons (0 through 9) will select numbered menu items directly, and enter time code values.

∙The KEYPAD buttons can also become ALPHA keys (ABC through YZ/), allowing files, drives, and directories to be given “real” names.

∙The +/- key toggles the Time Code Register between positive and negative values.

∙The * (star) key gives access to special Location Registers.

∙The SYM button allows you to enter special symbols that do not appear on the keypad’s ALPHA keys.

∙The CLEAR button clears the Time Code Register to 00:00:00:00.

∙In alphanumeric entry modes, the SPACE button enters a blank space.

Menu

The MENU button will present the menus associated with the Drive, Directory, File or Transport Screens.

File List

The TCR recorder offers a simple “Audition” Mode, allowing any file to be highlighted and played directly from the File menu. Just press PLAY.

The version button displays the software version number and machine I.D.

Save / Lock

The SAVE button will save a file you are working on, without closing it. The button lights as a reminder when changes have been made to the file.

The LOCK button changes the attributes of a file to “read-only,” and places a small Lock Icon ( ) on the display. In this mode, the file can be played but not altered.

Undo / Redo

The UNDO button will reverse the last operation and restore the previous version of a file. Whenever changes have been made to a file, the UNDO button lights to indicate that the operation may be undone.

The REDO button reverses the “undo” operation.

Headphone Jack

A standard 1/4" (6.3 mm) HEADPHONE JACK is provided on the left side of the front panel. The HEADPHONE button can be used in conjunction with the JOG WHEEL for convenient singlehanded level adjustment.

The headphone channel assignment is:

∙Tracks 1, 3, 5 and 7 to the left

∙Tracks 2, 4, 6 and 8 to the right.

The MON (monitor) buttons under the meters also function as channel-enable selectors for the headphones.

TCR Series User's Manual

Overview 2-7

ZIP Drive

A 250 MB ZIP® Drive is provided as standard equipment on the front panel.

The drive may be used as an audio source, and for economical storage of small projects.

Approximately 14 track-minutes of 24-bit audio can be stored on a 250 MB Zip® disk. It is also used to load new TCR operating software.

Function Key Section

The function key section provides an array of ten buttons:

R-M-W	MUTE	LOOP	REMOTE	OFFSET
VARI	OPTION	SLIP	DISP	CHASE

R-M-W

When Read-Modify-Write is enabled, only playback audio is available at a channel output, rather than the usual input signal. Audio may then be externally modified and re-recorded to disk, all in a single operation. The R-M-W button toggles the mode on and off.

Varispeed Play

When Varispeed playback is active, audio is played at an adjustable off-speed rate. Varispeed processing is accomplished by the DSP so that a standard output sample rate is always produced. The VARI button toggles varispeed mode on and off.

Mute

The MUTE button toggles the track Mute function on and off.

∙When MUTE is on, the MON buttons are re-defined as MUTE buttons. When a track is muted, its meters still function in the record mode.

∙When MUTE is turned off, any tracks that had been muted will remain muted, and blink their MON buttons as a reminder. All other MON buttons return to their standard purpose.

Option

This is a “spare” button for future use. It is presently used for Lamp Test whenever the File List is displayed.

Loop

When LOOP is active, playback will repeat indefinitely, with a small pause between cycles. The LOOP button toggles the Loop Mode on and off.

2-8 Overview

TCR Series User's Manual

Slip

The SLIP button allows individual time offsets to be introduced in selected tracks. When a track is slipped, the SLIP LED lights at the bottom of the track’s associated meter.

Remote

When remote control is active, an external device can control TCR. All Control Panel buttons with the exception of REMOTE are disabled. The REMOTE button toggles this function on and off.

Display

The DISP (Display) button activates a menu used for selecting display modes for the Transport Screen and the Time Code Display.

Offset

The OFFSET button enables and disables any time-offset that is currently set.

Chase

When enabled, the TCR is controlled by incoming time code, and the PLAY button blinks. The CHASE button toggles Chase Mode on and off.

Overview 2-9

Transport Control Section

Although the TCR recorder shares no technical kinship with tape-based products, it is convenient to continue many of the operational traditions, such as the notion of a “tape transport”, referred to in this book as just “transport”. Other tape terminology, as in the words “rolling”, “punch-in”, “punch-out”, “rewind” and “varispeed”, are to be taken in the spirit of analog ancestry.

The Transport Control Section contains five buttons, used to control the delivery of audio in a VTR-like fashion:

PLAY

STOP

REC

AUTO

REVIEW

Play

The Play button’s primary purpose is to initiate playback of a recorded file. In the TCR recorder, it can also operate in concert with other keys, or operating modes:

∙Press PLAY to play back any highlighted file on the Files Menu. The file will play from the Head Point to the Tail Point at normal speed.

∙While editing, press PLAY to play back a file from the cursor’s current position (that is, the value shown in the Time Code Display).

∙In the Loop Mode, press PLAY to repeat the file continuously.

∙Press PLAY + REC while the transport is rolling to punch-in to record mode.

∙While recording, press PLAY to punch-out of the record mode and keep rolling.

Stop

The STOP button will always stop all transport functions. When working with menus, press STOP to exit from the menu.

Record

Press REC + PLAY to start recording at the cursor’s current position.

From the File List, pressing REC + PLAY will create a new file in the current directory.

Auto-Record

The Auto-Record feature permits accurately pre-planned insert recordings to be made in an existing track. In practice, the user determines a punch-in point and a punch-out point. On pressing AUTO, the system will pre-roll, enter record at the Edit-In point, exit the record mode at the Edit-Out point, post-roll , and come to a stop.

Review

Similar to the “replay” mode in an editing system, the REVIEW key will place the TCR in an automatic review mode. The system will pre-roll and enter Play at the Edit-In point; playback continues through the Edit-Out point, and after a post-roll, the transport stops.

Drive Bay

The Drive Bay located below the control panel can house an optional hard disk drive, either as a fixed unit or installed in a removable drive carrier. When a drive carrier is installed, an illuminated digit above the drive lock indicates the drive’s numeric ID.

Jog Section

The Jog Section is used for transport control, and for making adjustments to other machine settings. As in the Keypad Section, many buttons have a dual-function.

ALT		SHTL
	ADJ -	ADJ +
ADJUST	EDIT IN	EDIT OUT

The Jog Wheel

The Jog Wheel in TCR is heavily weighted to provide a better tactile response than a light plastic knob. It combines the traditional video functions of Jog and Shuttle, and also the audio function of “Scrub” editing.

∙The Jog Wheel may be used to jog audio forward or backward at a variable speed, proportional to the rate at which the wheel is turned.

∙The wheel may be used in Shuttle Mode to play audio forward or backward, at a fixed speed proportional to the rotational position of the wheel. Play speeds up to 60x normal may be selected in Shuttle Mode.

∙Within Menus and Displays, the wheel may be used to scroll through a list of selections; to adjust a time code value; or to select alphabetic characters for text entry.

Pause LED

The PAUSE LED lights momentarily in both Jog and Shuttle modes when the transport is at zero speed.

Overview 2-11

Shuttle

Press SHUTTLE to change the function of the Jog Wheel from a jog control to a shuttle control. In this mode, rotate the Jog Wheel to shuttle the transport forward and backward at a speed proportional to the direction and position which the wheel is turned (up to 60x play).

ALT

The ALT button is provided for future enhancements.

Adjust

Many keys in the Jog Section change from transport controls to adjustment controls: On the Transport Screen, press ADJUST to display the Adjust Menu.

∙<< (Rewind) changes to ADJ-, which allows you to “nudge” a value down by one increment.

∙>> (Fast-forward) changes to ADJ+, which allows you to “nudge” a value up by one increment.

∙EDIT IN changes to, which allows you to move the Time Code Register’s underline to the left.

∙EDIT OUT changes to, which allows you to move the Time Code Register’s underline to the right.

The Jog Wheel changes to allow you to “dial in” values.

<</ Adjust -

∙Press << to rewind the transport at a fixed speed, ranging up to -60x play.

∙Press << twice to locate immediately to the next stop point earlier in time.

∙In “adjustment” mode, press ADJ- to “nudge” a value down by one increment.
