- 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 +26dBm into 600 Ohms, greater than +32dBu into 10KOhms.
- THD: Less than 0.025% at 1 Khz, Less than 0.05% at 100Hz.
- Frequency response: 20Hz (+0.3dB) to 20Khz (-0.2dB).
- Maximum Gain: Slightly greater than 80dB.
- Noise: Less than -100dBm.
- Power consumption: 106 mA @24VDC.
