Word clock issues

1 – Introduction—Word clock issues

The “word clock” in a digital audio system is the timing information that enables the digital audio samples in a system to be synchronized between the different devices. It is completely unconnected with timecode clocks, etc.

There must be one, and only one, word clock master device in a digital audio system. The DM-24 is capable of acting as a word clock master or as a slave.

WARNING

There should be one, and only one, word clock master in a setup. Multiple word clocks in a setup may result in noise. which can damage monitoring equipment (speakers and amplifiers).

Check with the other equipment that you are using to see whether it can be a master or slave, and work out which device will be your word clock master. If the DM-24 is to be a word clock slave in your system, it can accept word clocks from the following sources:

• An external clock connected through the dedicated connector

• The TDIF-1 interfaces

• The integral ADAT interface

• Either of the two

DIGITAL IN interfaces

• Either of the slots occupied by an optional digital interface card. In the case of an AES/EBU interface card, any of the four stereo signal pairs may be individually selectable as the word clock source.

• If two DM-24 units are being cascaded, the clock source on a cascaded DM-24 will always be the cascade master DM-24 unit. The master of the cascade chain can select its clock from any available source.

The clock can be at 44.1 kHz or 48 kHz or 88.1kHz or 96kHz with some variation possible for varispeed, etc. at ±6%.

NOTE

When the DM-24 is linked to an external word clock, it can only use a base frequency clock. Even when many external devices are operating at high sampling frequencies, they output such a base frequency clock. If the external device does not do so, and only outputs a high sampling frequency clock, the DM-24 must be used as the word clock master for the system.

2 – User interface

Scope of controls

The DM-24 has three main types of control screen: system screens, which control parameters for the whole of the system, “global” control screens which

Module screens

Alternatively, the screen can be used to show and set the parameters of one module (similar to a channel strip on a conventional console).

However, since the number of parameters and features available on the DM-24 is more than a single screen can display, four screens are available for each module, accessed through the soft keys (“Soft keys” on page 15).

5 Use the cursor keys, the soft keys and the

PODs to make changes to the module’s parameters. See below for details.

PODs

2 – User interface—Scope of controls

The DM-24 features four rotary controls immediately below the screen, called PODs.

These are used as “soft” controls to adjust parameters; that is, they have no fixed assignment to control any single parameter in the console, but are used to control a parameter which is currently highlighted on screen.

The POD controls have no end-stop, but are continuously moveable. The value of the parameter controlled by the POD is shown by the graphical onscreen representation of the control.

As part of the POD system, cursor keys are included, which move the cursor to the appropriate part of the screen.

In addition, the dial can usually be used to move the cursor around the screen. Usually when we mention that the cursor keys can be used for navigation, the dial can also be used, even when this is not explicitly stated.

Use the § and ¶ keys or the dial to move the cursor row (shown by a blinking box surrounding the row) up and down. Sometimes in some global screens (as shown here) the box does not cover the full width of

a screen row, and the Ó and Á keys or dial must be used to move the box within the row.

When a number of on-screen controls are highlighted by a box surrounding the row containing up to four on-screen knobs, the appropriate PODs are used to control the on-screen controls.

If the row also contains on-screen buttons, these are “pushed” by using the Ó and Á keys or dial to navigate to the button in the row (if necessary), and then pressing the

ENTER key.

Fine value settings using the PODs

By pressing and holding the 2ND F. key while turning a POD, the value set using the POD can be changed more precisely.

This feature is useful when the parameter being changed has many possible values (for example, the digital delay setting) which are first set using the default “coarse” setting, and then fine-tuned using the fine mode with the

2 When the parameter to be changed is high-

lighted as described above, use the entry dial to set the value (it starts to flash), and the

ENTER key to confirm the value set with the

dial.

Alternatively, if the parameter is an on-off switching button or a checkbox (a number of checkboxes can be checked individually), press the

ENTER key when the cursor is next

to the button or checkbox.

If the parameter is a “radio button” (one of a number of alternative options), simply highlight another radio button in the same group, and press the

of the buttons in the group.

NOTE

In some screens, (for example the module screens), the active area is marked by a flashing box. The dial is then used for navigation, rather than for setting values.

There are other screens, where the dial is chiefly, but not exclusively, used for navigation (e.g. the

OPTION

Using the faders to change values

In the global screens, there is often a special onscreen button, allowing the setting of the values in the screen directly using the faders.

To enable this feature, turn the on-screen

CONTROL

button to ON.

The name of this button is prefixed by the title of the screen (here it is an

AUX LEVEL screen which is being

edited).

When the button is turned on:

• The faders move to reflect the values set for the current parameter

• The fader layer key starts to flash (if it is a channel module layer and not the master layer—see “Fader layers” on page 18). This flashing key shows that the faders are not currently acting as channel faders

FADER

and that moving the faders will change the currently selected parameter, not the module’s signal level.

• Moving the fader of a channel changes the value of the current parameter.

• Using the POD to change the value of a channel’s parameter moves the corresponding fader if the layer is active. If the layer is not active, the fader will be moved to the new position when the layer is made active.

The status of the fader control setting is memorized between screens (and even when the DM-24 is turned off and on again). It is therefore possible for the faders to move when the screen is changed.

The layer continues flashing as long as the faders are not controlling the channel levels.

Soft keys

2 – User interface—Rotary encoders (ring LEDs)

At the bottom of a display screen, there may be some “tabs” displayed, which lead to further related screens or pre-defined action.

Soft key pull-up menus

In a few screens, for example, the library screens, where many soft keys are used for the “one-off” actions, a soft key (usually soft key 1) is used to bring up a small menu at the bottom of the screen:

The four keys at the bottom of the screen, beside the PODs, are used as “soft keys” to jump to the screens shown on the “tabs”. In this example, the and

OSC/COM tabs are controlled by soft keys 2 and 3.

NOTE

It is also possible to jump to the different screens by repeated presses of the key which brings up the screen (in this case, the

MONITOR

key).

MONITOR

These keys are sometimes used to perform a unique “one-off” action, as shown in this screen, where the oscillator can be turned on and off using soft key 1.

When such a menu pops up, either the dial or the POD corresponding to the soft key (usually POD 1) is used to select the desired option (which is highlighted in inverse video).

Rotary encoders (ring LEDs)

These controls allow you to set commonly-used parameters such as EQ parameters, pan and balance, and Aux send levels.

These are not dedicated controls, as the parameters which may be controlled using them are changed using selection keys, but their action is confined to fewer parameters than the POD controls.

Like the PODs, these controls are continuously moveable, and have no end-stop. Unlike the PODs, though, the parameters that they control may not necessarily be shown on screen. In order to gain an indication of the current value, the eleven LED indicators

arranged in a ring around the knob light to show the current value, as explained in the sections below.

These encoders have three different functions:

• EQ controls and pan controls to control the EQ

settings (gain, frequency and Q) as well as the current channel pan/balance of the currently active module. In this mode none of the encoder indicators (to the left of the encoders) is lit, and the band controlled is determined by the appropriate

EQUALIZER key.

TASCAM DM-24 Reference Manual 15

2 – User interface—Rotary encoders (ring LEDs)

• EQ gain controls, where the gain of the four EQ

bands is adjusted using these encoders. The encoder

EQ GAIN indicator is lit in this case.

• AUX send level controls, where either the encoder

AUX 1 through 4 indicators or the AUX 5 and 6

indicators are lit (in the latter case, only the two leftmost encoders have any function).

Encoders used as EQ gain controls

When the encoders are used as EQ gain controls, a unity gain (neither cut nor boost) is represented by the sixth (center) LED being lit, and the two LEDs at the extreme clockwise and counterclockwise positions “half-lit” (dimmed).

= on = dimmed = off

When the encoder is near the center position, but not quite there, the LED next to the center is lit, as well as the “end” LED on the appropriate side:

= on = dimmed = off

See the appropriate section on module operations (“Module operations” on page 49) for full details of the parameters controlled here.

NOTE

The option described in “Fine value settings using the PODs” on page 13 also affects the operation of these encoders when used in conjunction with the key.

2ND F.

If the EQ band is set as a high-pass for low-pass filter or is used as a notch filter (depending on the band), all LEDs around the rotary encoder are off:

= on = dimmed = off

When the encoder is turned either clockwise or counterclockwise, to boost or cut the gain respectively, the end LEDs go out, and the LEDs on the appropriate side of the center light (the more the cut or boost, the more LEDs will light). “Half steps” are shown by dimmed LEDs at the end of the chain. The illustrations below show a relatively small amount of gain applied, and then a little more gain:

= on = dimmed = off

Encoders used as EQ frequency controls

When the encoders are used to set the frequency controlled by an EQ band, only one or at most two LEDs are lit at any one time.

As the knob is turned clockwise, the ring LEDs light in turn, representing the position of the knob “pointer”. For greater accuracy, intermediate values

Encoders used as Q controls

The Q of an EQ band refers to the width of the filter when it is in notch or peak mode (but not in shelf or

filter mode). Low Q values affect a wide portion of the spectrum, as shown below:

= on = dimmed = off

Encoders used as pan controls

When the encoders are used to make pan settings, the center pan position is represented in the same way as unity gain on the EQ gain controls:

= on = dimmed = off

“Almost center” positions are shown in a similar way to the “almost unity” gain position (that is, the center LED is lit, along with the LED immediately next to it, with the end LED on that side being dimmed).

and high values affect a narrow frequency band:

= on = dimmed = off

Note that “intermediate values” are shown on the encoders by dimmed LEDs, as above. The LED pattern in Q mode is always symmetrical about the upper center indicator.

When the pan position is moved to either the left or the right of center, one (or two, to represent intermediate settings) LEDs light to show the current pan position.

The illustrations below show the pan position at the hard left position, and then at a position just right of hard left.

= on = dimmed = off

Encoders used as aux send controls

When the encoders are used as aux send controls and the control is turned clockwise, the LEDs light up, following the “pointer” of the knob.

The number of LEDs lit depends on the aux send level relative to unity position (0.0dB).

Below this position, the LEDs light clockwise, with intermediate positions shown by dimmed LEDs:

= on = dimmed = off

At the 0.0dB point, the LEDs representing values below this point are dimmed, and the “0” LED lights.

= on = dimmed = off

When aux sends are set above the 0.0dB level, the LEDs above the unity point light in sequence (intermediate positions shown by dimmed LEDs), with the LEDs below the unity point being dimmed. The diagram here shows a setting just below maximum (9.6dB):

= on = dimmed = off

The operation of the pan settings is as described for channel operations (“Encoders used as pan controls” on page 17).

Fader layers

The DM-24 has sixteen physical “channel” faders and one master fader. However, it is capable of accepting more inputs than faders (up to 32 channels), and also has eight output busses and six aux sends, which are often controlled on conventional mixers using their own faders.

To allow the sixteen faders to control the different parts of the console, the faders are arranged in “layers”. The layers are arranged as follows (as shown above each fader on the console itself):

Use the

LAYER STATUS keys located to the right of

the master fader, to switch between the three fader layers. The selected key lights and the keys are of different colors, as shown in the table above, so that it is easy to see which layer is currently active, even from a distance.

Machine control keys

As well as the keys controlling the DM-24 functions, there are also dedicated keys to control external devices connected to the DM-24.

Among these keys there are dedicated transport keys which allow basic transport control, as well as controls for auto punch and repeat control of external devices.

There are also strip, which are used to arm tracks on a connected device.

REC keys at the top of each channel

These fader layers also affect the use of the module

REC keys (used for arming the tracks of external

control devices), the

SEL keys, and the MUTE keys.

When the fader layer is selected, the faders move to show the current status of the layer.

AUTOMATION option is selected,

these indicators show the current automation status of the channels, as explained in the automation manual.

FADER SENSITIVITY This parameter allows you

to specify the sensitivity of the faders, as used in the automation process.

The DM-24 touch sensing capabilities are dependent on the ambient humidity and environment. Depending on these factors, it may sometimes happen that faders which have been touched are not recognized as having been touched, or the faders are recognized as having been touched when they have not actually been touched.

The value of the sensitivity is set by default to 4.0k, but you may wish to set it to any of the following values:

1.0k, 1.5k, 2.0k, 2.5k, 3.0k, 3.5k, 4.0k (Hz). High

values mean higher touch sensitivity.

While the switched

FADER SENSITIVITY on-screen button is

30DF (30 fps

current frame position is set to 12 (that is, halfway through a second), if the frame type is changed to 30 fps the frame position will be set to 15 (again, halfway through a second).

NOTE

When external timecode sources are used, the frame type is automatically recognized.

INT. START TIME If the internal generator is

selected as the timecode source, then the PODs are used to set the generator start time. Move the cursor so that the time is surrounded by an on-screen box, and then use the four PODs to set the hours, minutes, seconds and frames of the generator start time.

FLY WHEEL (frames) If an external timecode

source is selected, then it is possible to compensate for loss of incoming signal, allowing the DM-24 to “flywheel” for a set number of frames before it reports the loss of incoming timecode. The values available here are 8, 16 and 32 frames (the length of a frame depends on the frame type being received).

DIGITAL screens

The DIGITAL screens contain a number of different parameters affecting the digital audio operation of the DM-24.

There are three screens: the digital clock source is selected, the which provides facilities for controlling the format of digital data transmitted from and received by the
