อีควอไลเซอร์ BEHRINGER T1951
เอฟเฟ็ก T19514 band stereo parametric equalizer with hand-selected 12AX7 tubes UTC Ultra Tube Circuitry adds precise dosage of desired tube effect Parallel
The Behringer T1951 Tube Ultra-Q yields absolute control over audio signals, adding liveliness and presence to your music. Its 4 bands have an adjustable width from 0.03 to 2 octaves allowing easy attenuation of problem frequencies as well as creative sound design. Each Ultra Tube circuit features a 12AX7A to lend added warmth to the signal. The lo- and hi-frequency bands can also be used as shelving filters, allowing you to eliminate low-frequency disturbances and high-frequency noise. The Q principal filters ensure that level, frequency, and bandwidth settings do not affect each other, and its parallel filter architecture minimizes phase-shifting problems.
Features:
- 4-band stereo parametric equalizer with hand-selected 12AX7 tubes
- UTC – Ultra Tube Circuitry adds precise dosage of desired tube effect *
- Parallel filter architecture ensures minimal phase shift
- Precision state-variable filters with constant-Q characteristic
- Switchable shelving filter functions remove unwanted frequencies
- Each band can be bypassed and is fully adjustable from notch filter to broadband equalization
- Broad frequency band overlapping allows extreme boost/attenuation
- Relay-controlled hard bypass with auto bypass function in case of power failure
- Servo-balanced inputs and outputs on gold-plated XLR and TRS connectors for highest signal integrity
- Shielded toroidal power transformer for ultra low-noise performance
- High-quality components and exceptionally rugged construction ensure long life
- Conceived and designed by BEHRINGER Germany
