Alesis ADAT HD24 Remote Control Pin Out

Here are the measured resistance values for each button press on the remote control.

front panel of remote control

The remote control for the Alesis ADAT HD24 recorder uses combinations of 1/8 watt ±5% resistors to alter an input voltage.

I don’t have access to the recorder unit. Based on what I see inside the remote control I’m assuming it determines which button is pressed by measuring the voltage that is returned. Each button would lower the voltage by a different amount, thus making the measured value for each button press unique and identifiable.

The supply voltage that the recorder sends to the remote is unknown to me, but is likely one of the modern standard rail voltages — 3.3V, 5V, or 12V.

To obtain the following values I connected a digital multimeter across the tip and sleeve of the 1/4″ cable attached to the remote. All measurements are in Ohms.

Interestingly, the switch labels on the PCB differ slightly from the button labels on the case.

Also, I know this technically isn’t a pin out.

Switch Button Measured Value (Ω) PCB Label
N/A N/A 1406 (value read with no buttons pressed)
S1 Auto Loop 126 Auto Input
S2 Locate 0 279 Locate 1
S3 Loop Start 228 Locate 2
S4 Loop End 177 Auto 2>1
S5 Rehearse 76 All Input
S6 Set Locate 432 Set Locate
S7 Punch In 330 Locate 0
S8 Punch Out 381 Auto Play
S9 Rewind 1107 Rewind
S10 F Fwd 1207 F Fwd
S11 Stop 1008 Stop
S12 Play 899 Play
S13 Record 1307 Rec

Telling It On The Mountain

The story behind recording “Go Tell It On The Mountain.”

cover art

In case you missed all the promotional efforts on Facebook and Twitter, in 2011 I released my version of “Go Tell It On The Mountain” as a free download. Try one of the following links to get the song now.

The Recording

Many thanks go to Lynn Graber of The Recording House for offering to record this Christmas song for free as part of his Christmas 2011 compilation. Six other artists recorded songs with Lynn. I’ve embedded their tracks below for you to enjoy.

As for my recording, I had a lot of fun working with Lynn at his swanky studio. We experimented with new microphone placement and techniques while recording the upright piano. I also was able to track harmonica using an Alesis iO Dock with an iPad and the Ground Up Audio Amps & Cabs iOS app.

Lyric Changes

In 1907, John W. Work, Jr. published a collection called Folk Song of the Amer­i­can Ne­gro, which contained the first publication of “Go Tell It On The Mountain.” For those listening closely to my version of the song, some of the lyrics have been modified from the original. I altered a few of the words and added a couple lines. Some may want to stone me for changing a classic, but I believe the changes to be improvements that are faithful to our best understanding of the gospel. Review the lyrics on the discography page to see if you can find the changes I made. Let me know what you think via the comments section below.

Go Tell It

This song may seem old-fashioned or out-of-date, but here’s the thing: there are places in the world where people have never heard that “Jesus Christ is born.” They may know the name Jesus Christ (possibly as it is used as a profanity in movies or TV), or they may have limited information (or even disinformation) about this Messiah guy. In spite of the nearly omnipresent accessibility of the internet and prevalence of computers, smart phones, and iDevices, there are still many people uninformed about the central character of the Christian faith. Often, governments prevent their people from receiving information about Christianity or persecute their citizens for spreading the information.

One of the most notorious of these regions of the world is North Korea. With the recent passing of dictator Kim Jong-Il, the North Korean government is likely to change its policies in regards to religious practice. Please read this article from Vernon Brewer, president of WorldHelp, to find out how you can “go tell it on the mountain.” Then donate via this link.

I met my maker. I made him cry.
And on my shoulder he asked me why
His people won’t fly through the storm.
I said: ‘Listen up man they don’t even know you’re born.’
