T.C. Electronics DBMaxx

5-band Dynamics processing with preserved audio quality has been the primary concern when designing the DBMAX, hence you can even cascade several units without sonic penalities.

The DBMAX comes loaded with various processing tools e.g. 5-band dynamics, AGC, EQ, brickwall limiter and soft-clipper enabling you to have precise control of audio levels and dynamics in analog and digital production and linking.

The DBMAX makes it easy for you to handle technical level so you can make master recordings matching known requirements and ready for a variety of uses e.g. broadcast, and yet capable of being played on the very best systems. And you can easily move from client to client or target the mix for VTR, DAT or broadcast.

DBMax Transmission

Tomorrow's broadcast -will be digital! From Production, Continuity, Satellite and Microwave links to Final Transmission. The DBMax can perform transparent digital multiband limiting and level optimization.

When the switch is made to digital you will be ready for high resolution and high bandwidth with data compression codecs delivering optimum performance.

Try the DBMax and experience the world’s most extensive dynamics shaping tool for transmission application and improve your transmission NOW.

New features include
  • More presets and functions for Webcast and DTV
  • Spectral Stereo Enhancer
  • Improved wide range AGC
  • Distortion cancelling applied to Final Limiter
  • More soft clip functions for added loudness
  • Improvement of Dynamic Eq and De-esser
  • Input L/R channel swap function
  • Level set-ups can be stored to PCMCIA card
  • User lock can be maintained during power down
  • Optional auto-load of all settings on power up
  • More remote control functions via RS485/RS422
Maintain maximum level and simultaneously eliminate overshoots.
  • Maximum efficiency: 5-band compression.
  • Limiting: Sample accurate, distortion reduced Limiter.
  • Multi Slope: Add gain at mid-levels without squashing the transients.
The DBMAX uses precision calculations at a full processing rate to keep aliasing distortion low and audio bandwidth high.
  • Bandwidth: Processing at up to 48kHz sample rate for 24kHz frequency response.
  • Resolution: Processing of all 24 bits of an AES/EBU digital signal.
  • A/D-D/A converters: 24 bit resolution with analog pre-scaling.
AES/EBU, S/PDIF and analog Outputs are all active simultaneously. Digital Outputs may be dithered to resolutions between 8 and 24 bits. The optional TC Master Fader allows for post-processing real-time fades, or a fade time may be dialed in and an autofade executed.

Switch easily between AES/EBU, S/PDIF and analog Inputs. Sample Rate conversion is available on both digital Inputs.

With the DBMAX it is easy to move from client to client or to target the mix for a VTR, DAT, DAW or broadcast. Load your favorite preset and use different level setups to conform to any client’s specifications or standards.

Listen to your mix under varied and realistic conditions. By emulating different broadcast and listening environments, you can make corrections to your mix based upon the sound at the end listener.

The heart of the DBMAX is the most powerful dynamics tool you’ve ever heard: A five- band Compressor with adjustable slopes and cross- over frequencies. An advanced Look- ahead Delay can be used to reduce dynamic distortion and transient overshoots.

You can easily change the DBMAX multi- band structure from one to five bands.

Take control over individual band parameters or adjust them in groups.

Find a Preset you like and adjust the More / Less master compression control.

Insert blocks give you the ability to use plug- in types of processing tools before the 5- band Compressor/ Limiter/ Expander. Three simultaneous pre- dynamics inserts are available and you decide the order. Insert examples: Parametric EQ, Normalizer, Dynamic EQ/ De- esser, AGC (Automatic Gain Control), MS Encode/ Decode and Stereo Enhance.

Properly used multi-band compression is often a more desirable form of EQ. With the DBMAX you can do both. Use the multi- band Parametric EQ to adjust the spectral content of your mix and preserve or enhance its transparency and energy.

In a digital audio environment HF limiting is often required. The Dynamic EQ/De-esser in the DBMAX lets you perform dynamic notching or shelving over a wide frequency range, all within the digital domain.

Both the five-band and wide-band Limiters may be used simultaneously and each has variable look-ahead capability. The multi-band Limiter acts on peak material in each band.

The final wide-band Limiter ensures maximum level in either an Analog or a Digital peak sensing environment. Soft clipping may also be added for further optimization. DBMAX now enables you to deliver perfect results for both the Analog and the Digital environment.

The new Wizard function allows you to find perfect settings quickly. Based upon know-how from post production engineers around the world, the Wizard will produce optimum settings for you. Play a bit of your source material and press the OK key.

For alignment and signal check, many precision tools are included:
  • Peak Hold Meter with 0.1dB resolution.
  • Surround Meter showing L, C, R, S levels.
  • Phase Correlation Meter with time-base.
  • Internal Headroom Metering.
  • Oscillator for calibration 30 Hz-15 kHz at levels from -30 dBfs to 0 dBfs.
  • Digital Status Tool lets you monitor Input status and decide how status bits are handled through the machine - great when converting from S/PDIF to AES/EBU or vice versa.
