The Mackie MDB-1P is a passive direct box designed to connect a single instrument such as a guitar, bass, or keyboard to a microphone preamp for musicians and audio engineers in recording sessions, houses of worship, and live stage applications. It converts a high-impedance, instrument-level signal via its 1/4" TS unbalanced input to a low-impedance, mic-level output via its balanced XLR 3-pin jack. A 1/4" thru jack allows simultaneous connection to an amplifier or pedalboard.

A -15 dB pad reduces the input level to prevent distortion when using a high-gain source, and the ground-lift switch inhibits hum caused by ground loops. Due to its passive design, the MDB-1P requires no batteries or power supply. A sturdy steel chassis enables confident use in the studio or on the road.

Q: 1. What is the difference between LINE IN 3-4 and TAPE IN on Mackie 402VLZ4?

A: Tape in is just designed for playback and is routed directly to the output. Channel 3 and 4 is ballanced and will accept level signals.

Q: 2. Is there a delay with a USB-C connected cam camera vs an HDMI with an XLR connected mic?

A: The camera inputs for video capture on a streaming device for both video and audio, like the Mackie MainStream Live Streaming and Video Capture Interface are HDMI, not USB-C. As another option for a similar device with an XLR mic input, you may like the RODE X Streamer X Audio Interface and Video Streaming Console.

Q: 5. I need to know this, if I plug in the Syrp Genie with this cable to my Panasonic GH5, how should I set up the Gh5, or is everything setup with the Genie App?..and how would I make a Movie out of the time lapse in the Gh5 after I'm finish using the Genie with this cable connection? I don't want to buy this and then find out I need a post production program to put together the Time lapse movie....I want to do it inside the GH5?

A: If you read or download the manual for the GH5 you will see a mode that makes movies from timelapse photos in the camera. I use Adobe Lightroom and Premiere Pro as it gives me more flexibility. The Syrp Genie outputs a signal equivalent to pushing the shutter button on the GH5. So you need to set the GH5 into the mode you want. I am happy with the Genie as it is quite flexible when used with the camera App.
