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.
