Monoprice Sound Block (600125)

Revised version:

The sound block passive direct box with ground lift and attenuator is a versatile tool that can be thrown into a bag, trunk, or anywhere audio supplies are stored. Its heavy-duty construction and passive electronics make it nearly indestructible. This direct interface serves as a LO to Hi-Z transformer for electric instruments and devices, allowing them to connect to XLR mic inputs. Additionally, it can be used as lo-hi-z to use a microphone with a guitar amp, although this is not recommended due to guitar amps not being ideal pas.

The sound block can handle high level outputs from active instruments and even speaker outputs without any issues, thanks to the -20 or -40 dB attenuator switch. This passive device is easy to use - simply plug your 1/4" output from a guitar or electric piano, connect an XLR cable to your mixer's channel input, and you're all set. A ground lift is also included for use in older buildings with faulty wiring or in situations where circuits differ from the stage to the sound system location.

Key features of the sound block include:

• Heavy-duty 14 gauge steel construction
• Bi-directional impedance matching
• Compatibility with high output signals, including speakers
• Options for -20dB and -40dB pads
• Passive electronic design for ease of use
• Built-in ground lift to control hum and buzz on stage

Overall, the sound block passive direct box is a reliable and versatile tool for audio professionals looking to ensure clean and efficient signal flow. Its durable construction and user-friendly design make it a valuable addition to any audio setup.
