Used a few times. There's a slight feeling of use, but overall it's in a clean condition. There are traces of sticker removal on the back (please refer to the 6th photo). Connect Guitars and Basses Converts unbalanced high-impedance signals from guitars and basses to balanced low-impedance signals for mixer inputs. ■ Connect Keyboards and Line-Level Devices Setting the attenuator to -20dB converts signals from keyboards and line-level devices to signals optimal for mixers. ■ Connect Amplifier Heads Setting the attenuator to -40dB converts the speaker output of amplifier heads to signals optimal for mixers. However, in this case, it is necessary to connect a speaker to the THRU terminal of this unit. ■ Connect DJ Mixers Even with the -10dB line level of DJ mixers, converting to a balanced signal with this unit is convenient when long cable runs are required. ■ Specifications ・Ground Lift: Switchable ・Input Attenuator: Switchable (0dB, -20dB, -40dB) ・Input Impedance: 50kΩ ・Output Terminal: 600Ω XLR ・Parallel Link Terminal: 50kΩ ・Frequency Response: 10 Hz?50 kHz +/- 0.5dB @ +4dBu ・Dimensions: 146D x 127W x 51Hmm ・Weight: 1.1kg Thank you for viewing.
