It shows signs of use, but there are absolutely no problems with its operation or sound quality. The nut for the R channel's thru output is missing (please check the photos). There is no looseness or poor contact in the connector, but if you are concerned, you can install a generic one that fits (sorry!). Body only. Domestic genuine product. Quoted from the sales site below: ■Product Introduction The ProD2 is a 2-channel passive direct box for connecting stereo keyboards and high-output instruments to PA systems and home recording environments without noise or distortion. Equipped with two high-performance Eclipse ET-DB2 transformers, it has a frequency response of 20Hz to 20kHz, with a deviation of less than 1.5dB above 18kHz. It can handle signal level peaks without distortion, and unlike active circuits that overload due to exceeding the rail voltage, the transformer produces a natural limiting effect with saturation. This is particularly effective in rounding out and smoothing the excessive dynamics of digital pianos, samplers, and drum machines. The transformer is also excellent at eliminating hum and buzz caused by ground loops. ■Main Features 2-channel passive direct box designed for stereo keyboards Suppresses the digital feel with a smooth and warm sound Handles large transients without distortion Equipped with input pad and ground lift function ■Technical Specifications Audio Circuit Type: Passive, transformer type Transformer: Eclipse ET-DB2, 12:1 ratio Number of Channels: 2 Frequency Response: 20Hz～18.5kHz (±0.2dB) Dynamic Range: 128dB Total Harmonic Distortion: 0.01% (20Hz～20kHz, -10dB) Phase Deviation: 1° (at 100Hz), 8° (at 20Hz) Input Impedance: 140kΩ (unbalanced) Output Impedance: 150Ω (balanced) Maximum Input Level: +18dB (at 20Hz) Input Connectors: 1/4 inch jacks Output Connectors: XLR, 1/4 inch thru
