The S.M.S.L. SA-98E is a high-quality portable DAC with RCA inputs and outputs. - Model: SA-98E - Brand: S.M.S.L. - Volume Control: Yes - Input Terminals: RCA (red/white) - Output Terminals: RCA (red/white) - Power: DC 32V - Accessories: Power adapter *The included power adapter is not the one that came with the purchase; it has been replaced with a separately purchased one because the original's protection circuit was overly sensitive. While I don't notice a difference in performance, the output may be slightly reduced.
