Slate Pro Audio Dragon, 1 channel FET compressor / limiter, includes three character settings that change the way the unit sounds and responds. The first setting is BOOM. This setting adds sub bass harmonics in a unique way that when combined with some compression, can make basses sound massive and kick drums pound. The second setting is BITE, which adds a gentle forward character that makes the source more defined and clear. BITE is superb on bass, snare, vocals, and guitars. Last, is SHEEN. This character setting adds an airy gloss to the source, reminiscent of classic opto tube compressors. This setting is good on vocals, acoustics, and overheads. All character settings can be used simultaneously! 1176-style FET Gain Reduction Circuit, 1073 Class A Discrete Amplifier, 3 EQ-Emphasis Character Filters, Parallel Compression Mix Knob, Vintage and Normal Modes, Analog Tape-style Saturation Modes, High Pass Filter Side Chain, Ratios 2:1 to Squash, Input Impedance: 15K Bridged T-control (floating), Output Load Impedance: 15K Transformer balanced (floating), Frequency Response: 20 Hz to 20 kHz ± 1 dB, Gain: 45 dB, ± 1 dB, Distortion > 0.5% T.H.D.: from 50 Hz – 15 kHz with limiting, at 1.1 seconds release setting, Signal-to-Noise Ratio 0.5% T.H.D.: Output of +22 dBm with no greater than > 81 dB with input signal at threshold of limiting, Over a bandwidth of 30 Hz to 18 kHz, Attack Time: Adjustable, from 20 to 800 microseconds, Release Time: Adjustable, from 50 milliseconds to 1.1 seconds, External Connections: XLR / ¼" TRS (balanced), Stereo Interconnection: 1/4" Phone, Power Requirements 110V/220V, Power Connector Detachable IEC power cable, Dimensions: 19" "U, Weight: 5,44 kg
