Microphone input impedance: HI, 1200 Ohm minimum, LO, 300 Ohm minimum. Higher gain positions gradually have greater impedances, optimum for low gain ribbon mics. Input is transformer balanced and floating.
Line input impedance: 10KOhms bridging, transformer balanced and floating.
Output impedance: Less than 75 Ohms, transformer balanced and floating, to drive a load of 600 Ohms.
Maximum output: Greater than +26.5dBu into 600 Ohms (internally terminated)
THD: Less than 0.025% at 1Khz, Less than 0.05% at 100Hz.
Frequency response :20Hz (+0.3dB) to 20Khz (-0.2dB).EQ Off. For EQ ON frequency response please check the features section.
Maximum Gain: Slightly greater than 80dB.
Equivalent Input Noise: Less than -125dBu at 80dB mic gain.
Output stage noise: Less than -100dBu.
Power consumption: Less than 150 mA @48VDC.
