The Kramer 105A Distribution Amplifieris part of the mini-series of compact distribution amplifiers. It accepts one unbalanced input on a stereo mini-plug and outputs five identical stereo audio signals through 3.5mm mini plugs. Typical applications are for consumer audio equipment distribution or can be used in conjunction with video distribution amplifiers to distribute the audio for VCR's or DVD's.

Part of Comprehensive's mini-series, this unit is small enough to fit multiple units into existing rack space. It is also portable enough to use on location productions or in a multi-equipment audio-video situation.

Anything using an unbalanced audio signal can be distributed; consumer VCR's, DVD's, computer sound cards and background music are just some of the functions, only limited by your imagination.

This unit comes with an AC power supply as standard equipment and can also be powered with 12 Volts DC from an automobile, camera or other 12 Volt supply. With a VA-50P power supply multiple units can be used on one AC output.

Q: 1. Could I use this to replace a failed Kramer 123VXL?

A: I'm afraid not. The Kramer 123VXL was a Differential Video Line Amplifier with composite connections. This is an SDI Distribution Amp. Instead you'd want to look at the Kramer 104LN, which is a 1x4 Composite Video Line Amplifier, Differential Input.https://bhpho.to/2wDyTRM

Q: 5. what is the max. distribution distance ?

A: An HDMI signal travelling over a standard HDMI cable with no built in signal booster will generally have a distance of 50 feet.

Q: 6. This Kramer claims to boost HDMI signal to increase cable length. To what length? From reviewer comments it seems the cable can additively play a part in boost distance (ie boosted distance + cable capability = total distance).

A: Absolutely. I would not consider a DA a booster but only a DA. For installation I would install the DA as close to the source as possible, no more than a 6' cable and then no more than 50' cable on each output. It is very important to use use high quality cables with any HDMI installation. If you need to go further consider using a twisted pair Rx/Tx setup for best results.

Q: 7. Will this work with both Anaolg and Digital Signals?

A: I have used it in a couple of churches using HD cameras. And it has worked very well.

Q: 8. Is this an old picture? Our existing units are pewter grey. we want to be sure we get the same thing.

A: Indeed, it is an incorrect image. You would receive an all pewter device seen here: http://bit.ly/2phO3av I shall alert the webteam. We apologize for any confusion.
