DBX 286S Microphone Pre-Amp Processor

DBX 286S Microphone Pre-Amp Processor The dbx® 286s is a full featured Channel Strip Processor that delivers a studio quality microphone/instrument pre-amplifier and four processors that can be used independently or in any combination. Why mic up vocals and instruments through a noisy, blurry mixer? The sonically pristine dbx 286s Mic Preamp has all the features you need, including wide-ranging input gain control, switchable +48V phantom power, and an 80Hz high-pass filter to remove low frequency hum, rumble or wind.   FEATURES • Enhancer increases the detail and definition of the high and low frequencies • Frequency tunable De-Esser reduces sibilance and high frequency distortion• Classic dbx Compression puts great sound within easy reach• Insert jack allows you to add an external processor• Studio quality Mic Preamp/Channel Strip Processor• Full compliment of meters and status LEDs• Program adaptive Expander/Gate• Precision detented controls• +48V Phantom Power   SPECIFICATIONS • Enhancer LF Detail Characteristic ~ Bell-shaped boost @ 80Hz, bell-shaped cut @250Hz, ratio is approximately 2:1• Enhancer HF Detail Characteristic ~ Program-controlled shelving equalizer, approximately 15dB maximum HF boost• Compressor Attack Time ~ Program-Dependent; >1s for small level increases, down to 10ms for larage increases• Noise ~ <-80dBu unweighted (20Hz-20kHz); Both Gain Controls set for 0dB, all processing controls OFF• Compressor Release Time ~ Program-Dependent; adjustable between approximately 1dB/sec and 75dB/sec• Compressor Distortion ~ Typically <0.05%THD, 20Hz-20kHz, 15dB G/R, +10dBu Output, DENSITY @ 0• Expander/Gate Attack Time ~ Program-Dependent, approximately 2mS (at maximum attenuation)• Mic Preamp Phantom Power ~ +48VDC, applied to XLR pins 2 and 3 through 6.81kΩ resistors• Mic Preamp Equivalent Input Noise (EIN) ~ -125dBu, 22Hz-22kHz, 150Ω source impedance• IMD ~ SMPTE: <0.05%; 60Hz/7kHz 4:1, 15dB G/R, +10dBu Output Level, DENSITY @ 0• Insert Noise ~ <-84dBu, unweighted (20Hz-20kHz); LINE GAIN Control set to 0dB• De-esser Release Time ~ 12dB/octave Program-Dependent; approximately 1mS/dB• Operating Voltage ~ DO: 120VAC 60Hz, 100VAC 50/60Hz; EU: 230VAC 50/60Hz• Expander/Gate Release Time ~ Program-Dependent, approxiamtely 10mS/dB• Compressor Ratio ~ >4:1 For input levels beyond 20dB above threshold• Insert Connector ~ 1/4" TRS: Normalled; tip is Send, ring is Return• THD ~ <0.08%THD, 20Hz-20kHz, +10dBu, all Processing Controls OFF• De-esser Frequency Range ~ 800Hz to 10kHz High Pass, 12dB/octave• Output Connectors ~ 1/4" Balanced/Unbalanced TRS Connectors• Mic Preamp Connector ~ XLR Floating balanced, Pin 2 Hot• Input Impedance ~ (line) 10kΩ unbalanced, 20kΩ balanced• Insert Impedance ~ >5kΩ (ring-return); 100Ω (tip-send)• Input Connectors ~ (line) Floating balanced, TIP Hot• Insert Max Level ~ >+21dBu; >+20dBm (600Ω load-tip)• Max Input ~ (line) >+21dBu, balanced or unbalanced• Insert Distortion ~ <0.01% THD, 20Hz-20kHz, +10dBu• Mic Preamp max input level ~ 0.2Vrms, Gain = 30dB• De-esser Characteristic ~ Wideband Gain Reduction• Output Impedance ~ 100Ω unbalanced, 200Ω balanced• Frequency Response ~ 20Hz to 20kHz, +0.5, -0.5dB• Compressor Threshold Characteristic ~ OverEasy®• Expander/Gate Ratio ~ Adjustable 1.5:1 to 10:1• Expander/Gate Dynamic Range ~ Typically 105dB• Expander/Gate Threshold Range ~ OFF to +15dBu• Compressor Threshold Range ~ -40dBu to +20dBu• Input Gain Range ~ (line) -15dB to +45 dB• Max Output ~ >+21dBu, >+20dBm (600Ω load)• Gain Adjustment Range ~ -30dB to +10dB• Operating Temperature ~ 32°F to 113°F• Dimensions ~ 4.5cm x 14.6cm x 48.5cm• Shipping Weight ~ 6.54 lbs/2.97 Kgs• Mic Preamp Input Impedance - ~4.2kΩ• Expander/Gate Max Depth ~ >50dB• Mic Preamp gain ~ 0dB to +60dB• CMRR ~ >40dB, typically 55dB• Power Consumption ~ 15W• Max Compression ~ 30dB
