Metric Halo ChannelStrip 2 TDM OS X Metric Halo

Put a million-dollar console into your Pro Tools mixer!

Metric Halo’s ChannelStrip has been an integral part of the sound of myriad Grammy-award winning, Gold and Platinum records, hit TV shows and blockbuster movies. The first plug-in to bring classic large format console-style ChannelStrip processing to Pro Tools TDM, ChannelStrip has been the critical tool for getting “the sound” for thousands of professional recording engineers, composers and musicans world-wide.

ChannelStrip includes over 100 professionally constructed presets that are automatically installed with the plug-in that provide a wide variety of fix-its and starting points for optimizing the sound of your individual channels and mixes.

Ok. So now you know that ChannelStrip is the key to the “sound” of thousands of professional productions. You can check out the quotes and user stories on this ChannelStrip 2 Information Page (see below) to see just some of the folks who won’t work without it. But what is it? What will it really do for you?

Built for Pro Tools

ChannelStrip 2.2 is a complete overhaul of our 56k DSP code and Pro Tools plugin implementation. Redesigned from the ground up to take advantage of all the modern features and technologies of Pro Tools 7.3 while still providing support for earlier versions of Pro Tools, ChannelStrip for Pro Tools is now Universal Binary and supports all Pro Tools hardware including:

• Mix
• HD
• Accel PCI – All DSP types
• Accel PCIe – All DSP types

Note: ChannelStrip 2 is still available for sale to support Pro Tools TDM customers. If you are running Pro Tools 10 AAX (Win/Mac) or newer, or are using a Mac AU host, you should purchase ChannelStrip 3 instead (iLok required).

It’s all about the sound!

The consistent feedback we get from ChannelStrip users is that it just makes everything that they run through it sound better. Equally at home on individual instruments and on the master bus, ChannelStrip will warm up your sound, clarify the details and make your production sound pro.

How does ChannelStrip do this?

It’s all about attention to detail. High-precision algorithms, careful attention to rounding and dither, and deep integration between all the critical processes. On the one hand, its all a bunch of technical mumbo-jumbo, but on the other hand, it has the effect of breathing life into your audio… from virtual instruments to real ones, processing vocals and complete tracks.

ChannelStrip provides all the critical components of the channel strip of a large-format mixing console. The reason that large-format consoles (the classical “big iron” – SSL/Neve/Euphonix) include this kind of processing on each channel strip is that most signals benefit from the kind of interactive processing that all the elements of ChannelStrip provide together.

The Basics

ChannelStrip includes the following critical signal processors integrated together in one easy-to-use interface:

• Delay
• Expander/Gate
• Compressor
• EQ (48-bit – the first on the platform!)

The integrated delay is useful for adjusting the relative timing of tracks; this is great if you are recording sources (like a guitar amp) with multiple microphones. While this feature can be critical in a professional environment, it is a bit on the technical side, and you may find that you never need to utilize it. But it is there if you need it!

The Expander/Gate is a form of dynamics processing that is most useful for channels with real instruments or vocals; it provides an automatic gain-riding feature that effectively mutes the input or track when the audio level is too low. This is great when you have a noisy guitar amp or are recording a pod-cast and want to automatically mute out the rustling of papers and background noises. The Expander/Gate in ChannelStrip has a bunch of nice properties that make it really useful for maximizing the good part of a perfomance while cleaning up the unwanted noises. Another cool application for the Expander/Gate is its ability to change the rhythmic feel of a performance.

The Compressor is the primary dynamics processing element in ChannelStrip. Similar to the Expander/Gate, it provides an automatic gain-riding feature, but instead of the gain changing when the signal is low, the compressor changes the gain when the signal level is high. By lowering the gain when the signal level is high, the compressor can even out the dynamics of a performace, pull low-level detail out of the sound, and even radically change the nature of the sound passing through it. The compressor has been compared (favorably!) with the bus compressor in the SSL mega-bucks mixing console – a processor that is much coveted for its ability to “fatten up” everything that passes through it.

The EQ is, of course, the multiband equalizer. The EQ allows you to adjust the tonal balance and timbre of the signal passing through it. It is like a tone control on mega-steroids. The EQ in ChannelStrip is a 6-band fully parameteric, extended range, double-precision processor. Again with the mumbo-jumbo. In the end, it means that whatever sound shaping you require is possible with the ChannelStrip EQ. The parametric bands of the EQ are capable of deep notches and steep resonant peaks. This allows you to do unique things with the EQ – like re-tuning drums after they have been recorded. Whether you use this on real instruments or virtual instruments, the EQ allows you to maximize your sound.

The Not-So-Basics

ChannelStrip provides all the basic sound-shaping tools you need. But it doesn’t stop there; ChannelStrip adds some critical advanced features that you may not find elsewhere.

The most important advanced feature is the integration of equalized sidechains in both dynamics processors (the Expander/Gate and the Compressor). The equalized side-chain provides a fully-parametric equalizer in the side-chain of the dynamics processors, which allows you to tailor the response in a frequency sensitive way. This makes it possible, for example to make the compressor react more to the kick drum of a mix, or make the Expander/Gate that you put on a snare drum ignore the bleed from a hi-hat. This advanced feature makes the impossible possible and the difficult easy.

Another advanced feature of ChannelStrip is the integration and routability of the processes. One thing that you quickly learn when shaping sounds for a mix, is that all the signal processing stages interact. When you change the EQ, you also need to change the Compressor. When you adjust the Gate it effects the proper settings for the Compressor too. Sometimes the sound you are looking for requires the Compressor to come before the EQ, and sometimes the sound is best served by EQ and then compression. The User Interface of ChannelStrip supports this interactive process by integrating all the controls for all the signal processors into one control surface. The routing control for the order of the signal flow through the Compressor and EQ is integrated directly into the UI, allowing you to compare the effect of switching the routing with a single mouse click.
