Crosstalk
 Better than -115 dB at 1 kHz
 Better than -92 dB at 20 kHz
Input Sensitivity
 Low-Gain = 22 dBu (9.8 Vrms)

Trigger I/O
 12 VDC 200 mA current-limited output to trigger turn-on of remote devices
 DC input for slaving to remote devices
 Input responds to 3.3 V logic and higher, VIL = 1.26 V, VIH = 2.7 V
 Absolute maximum input voltage = 30 Vdc
 Absolute minimum input voltage = -0.3 Vdc
 Input Impedance = 20 k Ohms
 Two 1/8" (3.5 mm) TRS jacks
 Tip = 12 Volt Trigger I/O, Ring = no connection, Sleeve = chassis ground
Damping Factor
 350 at 20 Hz, 8-Ohms
 254 at 1 kHz, 8-Ohms
 34 at 20 kHz, 8-Ohms
 7 at 200 kHz, 8-Ohms
