TC Electronic 1210 Spatial Expander
The TC 1210 Spatial Expander + Stereo Chorus Flanger is the ultimate psycho-acoustic effect based on the Haas effect or the ‘Principal of First Arrival’. Utilizing the technology of TC’s world famous Stereo Chorus/Flanger Pedal, the TC 1210 has additional cross-coupled audio and independent clock circuits that produce dramatic enhancement of the stereo image. The wide bandwidth, high dynamic range and low THD mean that classic Analog Modulated Delay effects can be created without the noise and distortion normally associated with such units. The TC 1210 may be used as a true Stereo Chorus/Flanger or the two units may be split and used for two independent signals.
The Haas Effect
- Two independent Chorus/Flanger Effects
- Mono Compatible Chorus and Flanger
- Powerful stereo enhancement, utilizing the Hass Effect (The Principle of First Arrival)
- Syncable sweeps of the LFO clocks enhances the Chorus and Flanger programs
- Analog vintage sound with superb quality: 20-20,000Hz
- Adjustable Delay Time of 0.66 to 22 mSec.
- Phone (-10dB) and XLR (+4dB) Ins and Outs
- Additional set of phase inverted outputs available on Phone jacks
- Very low noise, Dynamic Range > 100dB<
The HAAS Effect or the ‘Principle of First arrival’ is a dominating cue by which the brain can pinpoint the origin of a sound within the boundaries that surround the listener.
Sound travels through air at approximately 1080 ft./sec. (340m/sec.) and arrives at each ear at slightly different times. This difference and the successive reflections assist the brain in determining the originating location of the sound.
By manipulating these arrival times the TC 1210 widens and adds "Space" to the stereo image. It is possible to give the impression that a sound comes from the right channel even if the volume of the left channel is higher, providing that the left channel signal arrives a little later.
The delay times needed to alter our perception of the position of the sound sources are so short that they are percieved more like filters than delays. The TC 1210’s individually adjustable L& R delay times and cross-coupled audio path combine delay and phase shift to play with the human ear’s ability to distinguish the origination of sound.
The images created are unique and effective without being blatantly obvious or offensive. Chorusing and Flanging utilize bucket brigade technology meaning the TC 1210 produces the Classic sound of ‘vintage’ units.
