Whether plugging in guitars, basses, electric pianos... you name it, the active switching and high input impedance of the Palmer RIVER Inn Active DJ Box delivers outstanding, detail-packed and reliable audio quality, without any loss of clarity or tone. Mono or Stereo This neat box has been set up to handle stereo instruments or can process two mono instruments at the same time. The THRU output also gives users the option to send the input signal to an amplifier; a fitted 30 decibel pre-attenuator can be activated so the Palmer RIVER Inn can be placed between the amplifier output and speaker to record the pure sound of the amplifier; and the Sum output can be used to send out the combined signal of both channels, saving you some valuable mixing channels. No More Interference or Ground Loops The balanced, low-impedance inputs ensure clean signal transfer and zero loss of quality when using longer cables. The integrated transformer and ground-lift switches are another welcome feature, helping to eliminate all possible interference, while the flexible power system can be run via 48 Volt phantom power or a standard power supply - whichever's most convenient in the moment. Professional, reliable and fuss-free, the Palmer RIVER Inn is a solid pick no matter the rig.
