|Line Voltage||100 V to 120 V / 108 V to 132 V|
|Line Frequency||40 Hz to 440 Hz|
|Max Power||120 W|
|Weight||2.3 kg (6 lbs)|

Option 2 adds internal pin headers for the slot as well as a rear 50-pin and BNC connector, allowing for custom wiring to and from the plugin.
On the standard TM501, cutouts for the 50-pin and BNC socket have been made in the rear frame, meaning that the user only needs to drill holes in the rear cover plate to install the sockets.
