Compact format audio mixer with 2, 4 or 6 mono input channels and a stereo line input. Each mono channel has a combo XLR/jack input with individually switchable mic/instrument impedance and +48V phantom power for the XLR. Input channels have High/Low EQ and Pan controls and mono channels also have Effects level to vary the amount of internal digital delay effect added for vocals or instruments. An internal player/recorder with backlit display can accept a USB memory stick containing compressed audio files in various formats or alternatively connect to a smart phone via BT wireless link. Output is delivered on a pair of balanced XLR connectors and offers very low noise operation for high quality studio or live performances.Power supply: 5Vdc 1A (adaptor included)vbCrLfOutput: Left + Right balanced XLRvbCrLfPhantom power: +48V individually switchable (XLR inputs only)vbCrLfAudio format: USB playback mp3, wma, ape, flac / record mp3 (48kHz 128kB/s)vbCrLfBluetooth version: 2.1 + EDRvbCrLfPower consumption max.: 5WvbCrLfMax. output level: 3VrmsvbCrLfDynamic range: 102dBvbCrLfFrequency response: 20Hz - 20kHz (±0.5B)vbCrLfTHD +N: <0.03% @ 1kHzvbCrLfCrosstalk : stereo: 92dBvbCrLfGain: -14 to +40dB vbCrLfEQ: low: ±15dB @ 80HzvbCrLfEQ: high: ±15dB @ 12kHzvbCrLfAudio source: Internal USB player/recorder & BT receivervbCrLfInput impedance : mic: 2k OhmsvbCrLfInput impedance : instrument: 1M OhmsvbCrLfInput impedance : line: 20k OhmsvbCrLfOutput impedance: 120 OhmsInputs: 6 x combo XLR/jack + stereo jackvbCrLfDimensions: 274 x 165 x 66mmvbCrLfWeight: 1.45kg
