INTRODUCTION

Introducing DB2

Consistency in loudness levels plus sync of audio to picture: These are the two most important issues you need to get right in today’s broadcast. They are also two of the reasons why TC Electronic’s DB range of high definition audio processors has set the standard amongst broadcasters the world over.

DB2 puts all of the tools necessary for trouble-free broadcasting into one rack-mountable unit, and adds to a scalable family of processors covering every application – from regional stations to network centers, from podcast to HDTV, from AC3 to linear, and from mono to 5.1.

DB2 is the new smaller brother of DB4 and DB8. It is the perfect choice for dual mono or stereo operation in MPEG, AAC, AC3 or linear audio transmission and linking. Performance is similar to its bigger siblings, and is also preset compatible across the range. Like the rest of the DB family, DB2 offers high-quality loudness correction without metadata dependence and is compatible with the latest ITU and EBU audio standards.

DTV Step by Step

With the launch of DB2, TC Electronic also introduces a new commitment to buyers of any DB processor: Within two years of the original purchase, users may upgrade DB2 to DB4 or DB8, and

DB4 to DB8, at only the price difference plus a modest handling cost.

For let’s face it: Nobody knows if your audience will prefer stereo, multiple stereo, multichannel, or something else – so we want to ensure that you can stay as flexible and as automated as possible at a minimum entry cost, yet retain a valuable option to upgrade.

The Transparent Loop

TC Electronic is the world’s premier supplier of automatic loudness correction equipment. It has developed a high quality loudness range trickle-down concept that works independently of metadata, but is nevertheless fully compliant with metadata in, for instance, the AC3 codec. DB processors not only automate loudness control in a proper way – they also help take the extra workload and unpredictable behavior out of the codec.

Applied in ingest and/or transmission, DB processors are part of a transparent loop, based on open

EBU and ITU standards, spanning from production over transmission to delivery at the home. Production can use metering of any brand compliant with these standards, including TC Electronic’s

LM5D radar meter, and obtain predictable results across broadcast platforms. News, soap, commercial, film, music, promo: All genres are covered.

Dither

Range: 8, 12, 14, 16, 18, 20, 22, 24, off

DB2 processes audio signals internally at 48 bit resolution. Dither must be set to match downstream devices.

Status Bits

Select whether the DB2 should send out

AES/EBU or S/PDIF status bit information.

GPI

The GPI input reads the analog DC level fed to this port, and may be assigned to a variety of functions: It may set the output level, add or change the on-line delay, enter and exit bypass, and make DB2 switch between up to 8 presets.

GPI Assign

Disabled

The device connected to the GPI port is disregarded.

Fader

Select this setting to enable GPI control of

DB2’s output gain. The DC level on the tip of the connector is read and used to adjust the output gain (“Output Fader” on the Engine/Limit page). Inside DB2, a 10 kOhm resistor is connected between +5 V and the tip of the GPI jack. Therefore, a passive external fader or potentiometer can be used to control the output gain. Use the Calibration function to optimize the control range for a given pot.

Bypass

Select this setting to enable bypassing DB2 using an external switch. Note that you may accidentally put DB2 to bypass mode when selecting between the GPI settings. The

Bypass function is defined on the System/Front page.

Delay

Select this setting to enable online adjustment of delay (e.g. for lip-sync) using an external

19

SYSTEM – I/O PAGE

switch or impulse relay. DB2 measures the time interval between two switch closures, and inserts this as its current delay.

(The “Delay” parameter on the Engine/Main page has a range from 0 to 1000 ms). Thanks to a silent update mechanism, the delay may be adjusted while audio is passed through the processor without introducing pitch change or click noise.

Preset

Range: 2 presets, 4 presets or 8 presets

Selection between up to 8 presets is achieved by feeding the processor a DC voltage to its ¼" jack input. The Input voltage is compared against voltage windows that correspond to certain presets.

Between the valid voltage windows, invalid windows have been inserted to protect against erratic operation. The processor constantly monitors the GPI input, and only if several consecutive measurements point to the same, valid voltage window, a recall is performed.

The voltage windows chosen enable easy

“binary relay encoding” as shown on the next page in fig. 1. If long cable runs are required,

HF decoupling using a ceramic capacitor across the tip and sleeve terminals inside the jack plug may be indicated.

The ring terminal of the ¼" jack is not used.

If GPI Preset mode is selected and no device is connected to the GPI input, the

DB2 will always recall preset 1 at power up.

Calibrate

Use this function to calibrate DB2 to a connected GPI controller (e.g. master control relays or a potentiometer such as the TC

Master Fader).

To calibrate the GPI controller:

• Connect the GPI Controller to the GPI Input jack and click CALIBRATE.

• Set the GPI controller to its minimum position and click “Set Lo Threshold”.

• Set the GPI controller to its maximum position and click “Set Hi Threshold”.

• Press OK to complete the calibration procedure.

GPI Current voltage:

Indicates the current voltage on the GPI Input.

With no GPI controller connected, the voltage is

1000 mV. Therefore it is worth noticing that the maximum indicated value on e.g. Master Fader is a lower voltage value than the minimum value.

GPI Technical Specifications

Inside the processor, a 10 kOhm resistor connects the tip terminal to a +5 V power supply. When nothing is connected to the GPI input, the input voltage therefore is +5 V. Resistors can be used to pull down the voltage as suggested in Fig 1.

In Table 1, voltages outside the limits mentioned are to be considered invalid. No action is taken if invalid measurements are made. GPI recall action resumes when a stable, valid measurement again is detected.

Rather than absolute voltage measurements, the windows are defined as a fraction of the supply voltage, Vs. This voltage can be measured with a high impedance DMM on the Tip terminal when no pull down resistors are applied. The table shows values as a fraction of Vs, and, as a guideline, typical voltages when Vs = 5.000 V. (If the supply voltage is e.g. 5.015 V, the table should be corrected by multiplying these values by 5.015/5).

Reference Level

Reference Level defines the standard operating level, and scales the Threshold and Target

Level parameters of the Loudness control and

Multiband section accordingly. The Threshold of the Limiter is not influenced by this setting, but is always relative to 0 dBFS.

Typical Reference Level settings would be -20 dBFS in the America and some parts of Asia, and -18 dBFS in Europe, Japan and some parts of Asia.

If you wish to relate all levels to 0 dBFS, leave the Reference Level setting at 0 dBFS.

Analog vs. Digital level

If you use analog interfacing, remember to always define the relationship between absolute analog and digital level before adjusting parameters in the Engines.

Typical analog I/O level scaling would be +24 dBu in the Americas and some parts of Asia, and +18 dBu in Europe, Japan and some parts of Asia.

Note 1: Be careful when switching between

configurations. Going from Dual Mono to Stereo will result in parameter settings of the left (or

“A”) channel being copied to the right (or “B”) channel. Going from Dual Mono to Stereo and back to Dual Mono will therefore overwrite the original settings for the right channel (or “B” channel)!

Note 2: In all configuration modes, linking of

the Brickwall Limiter is set separately on the

Limiter page. Some broadcasters like the sound of operating left and right limiting without stereo coupling because they feel that it maximizes loudness and widens the stereo image.

On dual mono sources, of course you should always choose un-linked Limiter operation.

26

MAIN PAGE

Configuration

Stereo: In this mode, the Loudness, EQ and

Multiband sections operate in tandem:

Whatever gain change is applied to one channel, is applied to the other. Also, many parameters have mutual left and right controls.

Dual Mono: In this mode, the Loudness, EQ and Multiband sections treat the two Input signals completely independently.

Stereo Wide: In this mode, the apparent width and image of stereo signal can be altered simultaneously with controlling loudness and peak level. The left and right signal is internally de-composed into an M (=

Mono) and S (Stereo) component, and reverted to left and right signals before peak limiting on the Output.

Sum Mono: Left and right channels are summed after Delay, Filters and AGC.

Left Mono: Only the left channel is being processed.

Right Mono: Only the right channel is being processed.

LOUDNESS PAGE

Target Level

Range: +10 dB to -10 dB

This is the level the Loudness controller will aim at on its Output. Target Level is relative to

Reference Level on the Main Page.

Example: When using the BS.1770 measure, with Reference Level at -20 dBFS and Target

Level at -1 dB, the loudness section of DB2 targets a loudness of -21 LKFS. For instance, this would be a typical setting for having

Dialnorm in AC3 set statically at -23 or -24.

Max Reduction

Range: -20 dB to 0 dB

This is the maximum attenuation the Loudness

Control is allowed to perform. If set to 0.0 dB, the Loudness Control cannot attenuate the signal at all. The level diagram on the next page is shown with Max Reduction set at 0.0

dB.

Max Gain

Range: 0 to +20 dB

This is the maximum gain the Loudness Control is allowed to perform. If set to 0.0 dB, the

Loudness Control cannot add gain to the signal at all.

Freeze Level

Range: -10 dB to-40 dB

Use this parameter to set the minimum level required before the Loudness Control will start adding more gain. It would typically be set to avoid boosting signals considered noise. The

Freeze Level parameter is relative to the

Reference Level setting on the Main page.

27

LOUDNESS PAGE

Freeze Hold

Range: 0 to 5 seconds

When the input signal drops below the Freeze

Level, the Gain Correction of the Loudness

Section is frozen for the period you set with the

Hold parameter. When the Hold period expires, the Gain Correction falls back to 0 dB gain.

Level Trim

Range: -18 dB to + 18 dB

Because DB2 internally operates with 48 bit precision on all audio signals, it is possible to correct loudness manually without the risk of overloads. The Level Trim can be used for permanent offsets or live loudness adjustments.

Ratio

Range: 1:1.25 to 1:6

Ratio is the steering factor used when the

Loudness Control applies boost or attenuation to reach the Target Level. The higher you set the Ratio parameter, the more rigid the signal is steered towards the Target Level.

Average Rate (Avg Rate)

Time constants in the Loudness Control section are changed dynamically along with the input signal, based on computations by multi-level detectors. When the Output level is close to the

Target Level, gain changes are relatively slow.

The Average Rate offsets all time constants to be faster or slower. Values below 1.5 dB/sec produce slow gain rides. However, for promos and commercials, higher rates are needed. At rates above 4 dB/sec, changes become less symmetrical – i.e. DB2 will turn the level down quicker than turning it up. This feature allows for rapid adaption without destroying the audio or adding gain “pumping”.

Slow Window

Range: 0 to 20 dB

The Slow Window is the area around the set

Target Level.

Within the Slow Window, the Loudness is controlled only gently. When the signal exceeds the limits of the Slow Window, the Loudness is treated more radically. The results depend on the values of the Average Rate and Ratio parameters.

Loudness Measure

ITU BS.1770

Use this setting to have loudness correction comply with the ITU loudness standard.

Reference Level plus Target Level is the value in LKFS DB2 aims for. For instance, if

Reference Level is set to -18 dBFS and Target

Level is set to -4 dB, DB2 targets a loudness of

-22 LKFS.

TC Grid

Use this setting to have loudness correction comply with TC’s legacy loudness standard

(called “Grid”). Unlike BS.1770, Grid is not

RMS-based.

EQ PAGE

EQ Page

Introduction

DB2 features a digital three-band parametric

EQ with high-pass and low-pass filters switchable between Notch, Parametric, Shelving and

Cut types. The needle-sharp notch filter has a range down to 0.01 octave, and the shelving filters has a variable slope, ranging from gentle

3 dB/oct. over 6 and 9 to 12 dB/oct. Cut filters can be switched between 12 dB/oct. maximum flat amplitude (Butterworth) or flat group delay

(Bessel) types. The parametric equalizer features a natural and well-defined bandwidth behavior at all gain and width settings.

Basic Operation

• Click the Lo, Mid and Hi buttons to activate/deactivate the EQ bands.

• Select Freq, Gain, Type or Lo/Hi to access all four parameters on individual bands.

• Click BYPASS EQ to bypass all three bands.

Type Selector

• Click TYPE and use faders 1 to 3 to select filter types.

For Lo and Hi filters, you can select between these filter types:

Parametric, Notch, Shelve and Cut.

For the Mid filter, select between these filter types:

Parametric and Notch.

5-BAND PAGE

Introduction

Multi-band processing can be used for evening out spectral differences between programs, optimizing levels and/or assisting the loudness correction when changes in loudness occur suddenly. Make your settings on the 5-band pages according to the task at hand.

The 5-band processor in DB2 may be used simultaneously with all other processing modules. The section may be switched to four, three or two bands or to “DXP” mode, which lifts low-level signals instead of performing regular multi-band compression.

Pressing Threshold, Range, Ratio, Attack and

Release buttons will immediately assign Lo,

Mid, Hi and All values for these parameters to

Faders 1 to 6.

The “All” parameter offers a relative adjustment of all bands. Its value reflects that of the Mid band.

Threshold

Range: -25 dB to +20 dB

Use this parameter to set the threshold for each frequency band in the compressor. Values are relative to the Reference Level parameter on the Main page.

Gain

Range: 0.0 to 18 dB in 0.1 dB steps.

Use this parameter to apply make-up gain to each frequency band. The gain is reflected on the 5-band meter on the Icon remote, thereby giving an idea of the frequency response of

DB2 when levels are below the threshold of compression.

Ratio

Range: Off to Infinity

Use this parameter to set the ratio for each frequency band in the compressor.

Attack

Range: 0.3 to 250 ms

Use this parameter to set the attack time for each band of the compressor.

Release

Range: 20 ms to 7 sec.

Use this parameter to set the time it takes for each compressor band to recover to unity gain.

Bypass Comp.

Click to this button to bypass the 5-band compressor.

Click this button to access the four cross-over points between the five bands. The parameters are automatically assigned to faders 1 to 4.

Parameter Range:

Xover 4:

Defeat Thresh

Range: -3 to -30 dB

This is a unique control which defeats gain from the multiband compressor below a certain threshold. No matter what spectral shaping is applied from the multiband system: Below the

Defeat Threshold, the frequency response is flat and gain is unity.

Defeat Threshold is relative to Compressor

Threshold, which is relative to Reference Level.

Defeat Ratio

Range: Off to Infinity

Controls how close to the Defeat Threshold the make-up gain of the compressor is counteracted. At high ratios, the signal only has to be slightly below the Defeat Threshold before the compressor gain is fully defeated.

32

5-BAND PAGE

DXP Mode – Introduction

The 5-band section works either in normal compression mode or in DXP (“Detail Expansion”) mode. Instead of attenuating signals above a certain threshold, DXP mode lifts up signals that are below the Threshold; thereby bringing out details rather than squashing the loud parts.

DXP mode therefore is capable of adding intelligibility and air to speech, lifting harmonics, or emphasizing ambience without increasing overall peak level.

Try setting the Steer and/or Threshold parameters differently in the bands to hear the effect.

High Steer values add more detail gain than low values, but remember that Threshold has to be negative to add detail gain at all.

DXP Threshold relates to the Reference Level set on the Main page.

To disable DXP detail gain at very low levels, use the Defeat Threshold and

Defeat Ratio controls. Defeat threshold relates to the DXP threshold, and allows for a certain level-window, inside which detail gain is applied. Defeat Ratio determines the slope at which DXP detail gain is defeated.

As shown in the illustration, gain is positive below threshold, unity at Threshold, and the effect decreases above Threshold. In DXP mode, Ratio becomes Steer. Steer can be regarded as an adaptive Ratio that gradually approaches 1:1 above the threshold.

Multiband DXP

DXP mode can be used with any number of bands (up to five). Multiband DXP is particularly effective in bringing out air and clarity.

The processor can act as an automatic EQ that removes a boost when it’s not needed: at very low levels (where noise is dominant) and at loud levels (where sibilance would become a problem). Apart from being effective on speech,

DXP mode can also be used in mastering to bring up low levels – e.g. when preparing film or concerts for domestic or noisy environment listening.

33

LIMITER

Link Limiter

Range: On/Off

When Link is active, the same amount of peak limiting is always applied to both channels.

Some broadcasters like the sound of operating left and right limiting without stereo coupling because they feel that it maximizes loudness and widens the stereo image. Of course you should always choose unlinked Limiter operation on dual mono sources.

The Configuration control on the Main page does not affect the Link Limiter setting. This link is running individually from the selected configuration.

SoftClip A/L and B/RSoftClip A/L and B/R

Parameter range: -3 dB to Off

When active, SoftClip applies a saturation effect to signals that come close to maximum

Output level. The threshold is relative to the

Threshold of the Brickwall Limiter.

This controlled distortion of transients works well for adding loudness, but is not a desirable effect with some data compression codecs.

While the Brickwall Limiter is extremely low distortion, SoftClip is not. Use your own judgment to decide whether it improves your production or not.

Threshold A/L & Threshold B/R

Parameter range: -12 to 0.0 dBFS

Use these parameters to set the Threshold of the Brickwall Limiter.

The Threshold is relative to 0 dBFS, not to the

Reference Level set on the Main page.

The Brickwall Limiter uses 48 bit processing,

34

with distortion figures surpassing the quality demands of DVD-Audio mastering. Oversampling is used to prevent inter-sample peaks from reaching the Output, and time-constants adapt to the Input signal.

Emphasis

Emphasis compensation may be added to the limiter. DB2 uses a sliding low-pass filter to complement the limiter. While emphasis is used in analog broadcast, low bit rate codecs may also benefit sonically from this function.

Switch between emphasis Off (HD and normal

DTV broadcast), 50 microsec, 75 microsec and

J17 (NICAM) emphasis. Note: When pronounced Emphasis Limiting is required, it is normally advisable to link the limiters to avoid a wildly changing stereo perspective.

HF Offset

For Emphasis Limiting with no headroom against the response curve, choose a 0.0 dB setting. For analog transmission, a more conservative setting is suggested, e.g. -1.0 dB or lower.

This parameter is only used when Emphasis

Limiting is set to another value than “Off”.

DB2 PRESETS

The following Factory Presets are available with software version 1.0. All presets feature ultra-low latency loudness correction and true-peak limiting.

Factory presets assume that the AES3-id input is used. If you require analog or SPDIF input, recall a preset, go to the Engine / I/O page and select the appropriate input. For analog I/O, remember to adjust the “Level at 0 dBFS” parameter to comply with your requirements.

If DB2 is processing for a wide dynamic range platform (such as DTV or internal station linking), the

Limit Threshold on the Limit page may be raised to -3 dBFS or even higher. For AC3 transmission, however, the Limit Threshold should not go much above -6 dBFS to avoid distortion in consumer devices.

If DB2 is processing for a low dynamic range platform (such as IPTV or MobileTV), the Limit

Threshold on the Limit page may be lowered 2-3 dB, and the Ratio on the Loudness page raised to

1:4.0 or higher. More pronounced 5-band processing may also be added by bringing down the “All

Threshold” parameter on the 5-band page. With a lower threshold, you may need to prevent the level from dropping by adding Gain to some or all bands of the multiband processor.

Finally, consider activating the Lo Cut and Hi Cut filters on the Main page.

When you have finished editing parameters, be sure to store the revised settings in one of the User

Banks (U1 to U8) on the Library page.

SELF TEST

Accessing the Self-Test Routines

• Press and hold the OK key while powering up the DB2 to access the self-test.

• Press UTILITY to select “T”.

• Press OK to enter.

• Press UTILITY to select test-number and press OK to start the test.

Test 0 – LED test

Turns all LEDs on.

Test 1 – Analog In/Out Test

Connect a balanced cable between ONE analog Output and ONE analog Input.

The Input meter for the used Input should show

-12 dB.

The symbol “+” will indicate that the test for the currently used input and output combination is positive.

The symbol “-” will indicate that there is a problem with the input or the output. In this case, try the test with the other analog input/output to narrow down the problem.

Connect the cable to the other output and input in order to test these.

Test 2 – AES/EBU In/Out Test

Connect AES/EBU Input and Output using a balanced cable.

The INPUT meters should show 0 dB. The symbol “+” will indicate that the test is positive.

The symbol “-” will indicate that there is a problem with the input or the output.

Test 3 – S/PDIF In/Out Test

Connect S/PDIF Output and Input using an

RCA cable.

The Input meters will show 0 dB.

The symbol “+” will indicate that the test is positive.

The symbol “-” will indicate that there is a problem with the input or the output.

Test 4 – RS232 remote I/O Test

Connect Rx and Tx on the RS-232 connector

(pin no. 2 to pin no. 3).

The symbol “+” will indicate that the test has been completed successfully.

The symbol “-” will indicate that there is a problem.

Test 5 – GPI Input Test

Connect the tip and sleeve of the GPI Input jack using a switch.

When the switch is closed (tip is connected to ground) the symbol “+” should be shown, otherwise the symbol “-” is shown.

Test 6 – Battery Test

The battery voltage is tested. If it is within limits, the symbol “+” is shown, otherwise the symbol

“-” is shown.

Test 7 – System Test

The ASIC, DSP, DSP RAM and EEPROM are tested while the digit “7” is flashing.

The symbol “+” will indicate that the test results are positive.

The symbol “-” will indicate that there are problems.

Test 8 – Ex.RAM Test

The Ex.RAM memory board is tested for one minute while the digit “8” is flashing.

The symbol “+” will indicate that the test results are positive.

The symbol “-” will indicate that there are problems.

Service Note

In case of the unlikely event that the unit needs to be sent in for service, please pack it in the original box AND an outer box before sending it.
