SDR 24/96

Appendix A: Troubleshooting and Service

If you think your SDR24/96 has a problem, please do everything you can to confirm it before calling for service, including reading through the following Troubleshooting section. Doing so might save you from the deprivation of your Mackie Digital Audio Recorder and the associated suffering.

Of all Mackie products returned for service (which is hardly any at all), roughly 50% are coded “CND” — Could Not Duplicate, which usually means the problem lay somewhere else in the system. These may sound obvious to you, but here are some things you can check:

Troubleshooting

No power!

•Our favorite question: Is it plugged in? Make sure the detachable linecord is pushed firmly into the AC socket on the back of the SDR24/96. Make sure the AC outlet is live (check with a tester or lamp).

•Our next favorite question: Is the POWER switch on? If not, try turning it on.

•Is the red LED above the power switch lit? If not, make sure the AC outlet is live. If so, refer to “No Sound” below.

•The AC line fuse inside the cabinet is blown. This is not a user-serviceable part. Refer to “Repair” on the next page to find out how to proceed.

No sound getting recorded

•Is the Input Type Select (SETUP:I/O:Page Right:Page Right:INPUT TYPE SELECT) correctly set to the inputs you are using, analog or digital?

•Is the signal source turned up? Make sure the signal from the mixing console is high enough to move the meters on the SDR24/96.

No sound on playback

•Are the tracks mapped directly to the outputs? If you have customized the track-to-output mapping (SETUP:I/O:Page Right:TRACK OUTPUT SELECT), make sure you are monitoring the correct output to listen to the desired track(s).

Can’t rewind to zero

•Is the transport offset (SETUP:Transp:Page Right:TrOf) set to something other than zero? The transport locator time will be offset by whatever value is entered in the transport offset field.

Noise/Hum

•Check the signal cable between the mixer and the recorder. Make sure all connections are good and sound.

•Make sure the signal cable is not routed near AC cables, power transformers, or other EMI-inducing device.

•Is there a light dimmer or other SCR-based device on the same AC circuit as the monitor? Use an AC line filter or plug the amplifier into a different AC circuit.

•If possible, listen to the signal source with headphones plugged into the console. If it sounds noisy there, the problem’s not in the SDR24/96.
