Product review: Digital Signage Audio Tripper

Posted: December 16, 2009 at 1:33 pm   /   by   /   comments (1)

Christmas is fast approaching and we decided to review a product before the end of this year. It has taken us a while to complete this review as it involved using a video camera and editing the video but from this experience we can hopefully improve our processes and review more products next year.

The Product – Andrew’s Audio Tripper AS-7

The audio tripper is a two way automatic audio switcher. It has two audio inputs; a default input, a sensed input and an audio output.

In its initial state the tripper selects the default input through the output. Whenever an audio signal is fed to the sensed input, the tripper will automatically switch to this input. The LED (green light) indicates that the sensed input has been selected. Once the signal to the sensed input stops, the tripper will switch back to the default input.

There is a delay control that can be used to adjust the amount of time the tripper waits before switching back to the default input. A delay would be preferable in the case of a multi CD player, for instance, to allow for the time taken to switch between discs.

The Setup

For our testing purposes we connected the unit as follows (I thought I’d be different and sketch the diagram by hand):

In this particular setup, we used a mobile phone as a default audio input – we thought we’d be creative and use a portable device that everyone carries around.

For the sensed input, we used the audio output of a digital signage player. The digital signage player was connected to a 19″ LCD screen and played scheduled content in a playlist. The playlist contained three items:

1. Image of product review email – has no sound

2. 15 second Advertise Me promotional video created by Blue Pony – has sound

3. Image of John Mayer Listening to… – has no sound

The output of the audio tripper is connected to a speaker. So what basically happens is that when the audio tripper doesn’t sense any audio coming from the digital signage player i.e playlist item 1 & 3, it will play audio from the default input i.e. mobile phone.  All RCA audio cables were used for these tests.

Our Verdict

  • We tested several audio input sources – mobile phone (Nokia n95, iphone, blackberry storm), a CD player and also a digital signage player and didn’t find any issues with the switching or the quality of the audio.
  • We have actually used this unit for one of our clients and we haven’t had an issues.
  • The only thing to consider is that if the unit looses power, it will not perform the switching but it will still continue to play the default audio input – so at least there will be audio
  • We would recommend to decrease the delay to the minimum setting (rotate anti-clockwise)
  • Can be used for many purposes – ie. backup audio for continuous music

You may ask yourself when would you use this type of setup and to be honest if you had a digital signage player, you could schedule the audio to play directly from the player but there will be certain situations and environments like a retail store, that you may need to give some control to the local store manager to play their own audio CD’s.
