Sound block passive direct box with ground lift and attenuator

throw the sound block in a bag, Trunk, or anywhere cable and misc. Audio supplies are stored. The heavy-duty construction and passive electronics make the sound block nearly indestructible. This direct interface is extremely versatile as a LO to Hi-Z transformer for electric instruments and devices to XLR mic inputs or as lo-hi-z to use a microphone with a guitar amp (not recommended only Because guitar amps make terrible pas). high level outputs from active instruments and even speaker outputs are not a problem when using the -20 or -40 dB attenuator switch. The sound block is a very easy to use passive device. Simply plug your 1/4" Output from a guitar or electric piano, plug an XLR cable into your mixer's channel input, and you're done.
