Single channel tube preamp w/ de-esser, compressor/limiter/noise gate, EQ and headphone amp. (Model #2950)
Details
The Channel One comes with all tools onboard for recording voices, instruments and digital or analog audio sources with the highest sound quality:
- Transistor/tube preamplifier
- SPL's De-Esser
- Compressor/limiter with noise gate
- EQ section
- Headphone monitor
- Options: 24/96 A/D converter, Lundahl I/O transformers
Each stage contributes to the concept as the ideal recording frontend for world-class sounds the easy way: intelligent automation ensures both intuitive and fast as well as musical operation for the finest recording results.
The preamp stage
Provides three optimized inputs:
* The microphone input features 48V phantom power, phase reverse function and a subsonic filter.
* The low-impedance Line input has a precise balancing stage for connecting studio equipment.
* The low-noise, high-impedance instrument input is easily accessible on the front panel.
De-Esser
The renowned SPL De-Esser subtly yet effectively removes offending sibilants by reliably eliminating only the "S" frequencies with its unique phase-canceling processing technology. Auto-Threshold ensures constant processing even with varying microphone distances. All you need do is to turn the knob until the sibilants are gone.
Insert (Send/Return)
The Insert (Send/Return) allows for insertion of external processors or can be used to record the pure preamplifier signal.
Compressor/Limiter
This section is based on SPL's Double-VCA-Drive® circuitry for outstanding noise and distortion characteristics. The compressor is extremely easy to use via a single knob. But the signal-dependent automation not only allows for set and forget operation, it also grants very musical results in any situation. Actually it is much more difficult to destroy a recording with wrong compression settings.
Noise Gate
The noise gate operates flawlessly - reverbs are recognized and not cut off.
Three band EQ
The Channel One provides a new EQ design especially optimized to process vocals, acoustic and electronic instruments. Low, Mid Hi, and Air-Bands allow for both corrective adjustments and/or effective sound designing processing. Gadget: a distortion control might be useful sometimes to apply for decent distortions to signals that deserve it.
Headphone monitor stage
Provides an individual mix for the singer/speaker - latency problems from digital systems are avoided.
Options
Optional equipment includes a 24/96 A/D converter and Lundahl I/O transformers.
