The InnerTUBE Audio Atomic Squeeze Box is a single-channel compressor/limiter which employs a proprietary dynamic control circuit which doesn't impart any of the sonic artefacts usually associated with compression or limiting.
The InnerTUBE Audio Atomic Squeeze Box is designed to control the amplitude of an audio signal that is passed through it while imparting virtually none of the sonic artifacts traditionally associated with compression and limiting. In short, it does not have a sound, though it is this very fact that will help make your final product sound better. As such, it can take a little getting used to, and new users sometimes find themselves experimenting with steep ratios and low thresholds just to "hear it working." As you learn to dial in exactly what you need, though, you'll begin to find that owning an ASB is best compared to having a skilled assistant, who knows the program material backwards and forwards, riding faders.
From its etched front panel and stalwart 2RU chassis to its beefy, positive-action controls and curved VU meter cutouts, the Dual Atomic Squeeze Box oozes quality. A Link switch and duplicate rotary controls for its two channels accommodate either true stereo or dual-channel operation. Continuously variable input and output level attenuators adjust respective gain from maximum down to infinity cut. The squeeze (threshold) and attack time controls are also continuously variable, whereas the release time and slope (ratio) controls are stepped. For each channel, the release time's range can be modified by two three-way switches: mode (marked slow, medium and fast) and hold (a release time multiplier marked 1x, 2x and 3x).
