It is ideal for recording studio applications, where it can be used to drive small reference speakers, or as a headphone driver for the HR-2 headphone remote stations, while doubling as the tape playback amplifier in the tracking room.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003eThe SP-20A may be operated in any of three modes as selected by a rear-panel switch: normal stereo, two channel mono, or single channel (bridged) mono. The latter mode allows a power output of 40 watts provided the load is 8 or more ohms. Output is available through either of two connectors. Standard banana jack binding posts for speakers, or through a male XLR connector. The latter allows the unit to become the headphone driver.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003eThe amplifier has an input level control on the left side of the front panel.

Another pair of red LED's warns of any overload condition present in either channel.
