Alesis SR-16 Battery holder

I have an older Alesis SR-16 that must have had the battery holder removed. Does anybody know where there is a circuit board diagram available on the internet, or what type of battery holder goes in it?

What you need is 2 unlatched switches 1 for the stop start function and one for the drum fill function.
I bought mine from my local music shop for £15 ea

Buy the correct adapter that matches the voltage AND current requirements of the unit. MANY universal ones do not and the original MAY have built in filter that universal does not.

You MAY also need to do a factory reset on the unit.

you may well have to go via a third unit, a computer or laptop to store the data then send it back to the other machine.

SOURCE: HI , MY ALESIS RS-16.

Cut and pasted info to replace the internal memory battery:

There is a battery inside the unit which is used to retain settings and beats that you program into it. This battery should probably last about ten years or so. If your SR-16 will not remember things anymore, it may need a new battery. Alesis can replace it for you, but this may cost $50.00 or so plus the cost and trouble of shipping. Anyone who can use a soldering iron can replace the battery. To disassemble the SR-16, remove the six screws on the bottom. There is a ribbon cable that connects the top and bottom together. This should be unplugged from the bottom part (main circuit board). The pins on the connector are very fragile, so pry it up carefully with a screwdriver. Also the volume knob has to come off. To remove the circuit board, just unscrew the nuts on the six phone jacks on the back. The battery is a coin-shaped 3-volt lithium battery. The one in mine is a Panasonic BR2325. If you buy a replacment battery, you will need to get one that has PCB terminals on it so it can be soldered. I THINK this is Panasonic part number BR2325-1HB (theres lots of different types of connectors on these). You will not find this at Walmart. It will need to be ordered from an electronics supply place. Digikey has them for $2.00. I think you can get one from Alesis for 15 or 20 dollars.

Hello I recompose my question. J would like to know the value of the ceramic condenser close to connector VAC of the circuit of Sr-16. On the circuit C5 opposite the condenser is written. it is round


You might try going to this webpage
https://www.alesis.com/sr16
and from the docs&downloads section download and search the Reference manual. It's also here http://www.burnkit2600.com/manuals/ALESIS_SR-16_OM.pdf (this looks more like a user guide though)
Failing that, choose 'support' from the th top of the page and either contact Alesis support or else ask your question in the 'community' (which you will have to join). Another community which deems to have an interest in the SR-16 is www.circuitbenders.co.uk but I think it unlikely that they could direct you to a circuit diagram, though it is slight possibility that someone might know the value of the capacitor C5

When i disconnect power I lose user settings


Likely the backup battery is exhausted. Some of these are in a battery holder, others solder into the board with tabs. Measure the voltage of the cell. If less than 2.75 volts replace it. The cell will likely be designated something like BT1.

Ihave an Alesis D4 drum sampler.I have not used in several years I have hooked it up now an everything lites up but I cant get any sound out of it. with triggers or pads?


Some of the Alesis products have a setup and data memory backed up by a battery. It is POSSIBLE that your battery expired and took the sound memory with it.

Investigate if you have a battery in yours (buried in the guts) and check the voltage. It should be above about 3 volts.

If it is below that, replace the battery and find another unit to clone the data from.

SR-16 gives message "ERROR: 01" when powering up


You likely have lost the internal memory data. This can be due to a power surge or that the internal battery has been depleted. The battery may need to be replaced.

You should reset the unit and reload the data, The manual is available online. Search Google for it.

The manual STRESSES the importance of backing up the data.

If you don'thave the backup, you MAY need to find another SR-16 owner to clone the data from.
