9.4 TROUBLE-SHOOTING
9.4.1 Audio issues – standard version
If you get no sound while playing music, start the miniDSP-2x4-HD plugin. Then work through the following
steps.
If there is no signal on the input meters
1. Check which input source you have selected.
2. Double-check the connection and cabling between the source(s) and the miniDSP Flex.
If there is signal on the input meters, but no signal on the output meters
1. Check the master volume setting.
2. Check that the miniDSP Flex is not muted (Mute button at top right of the interface).
3. Check your Routing and make sure that you are routing inputs through to outputs.
4. Check your crossover settings.
If there is signal on the output meters, but still no sound
1. Check that output cabling is connected to the right connectors on the rear panel and to the correct inputs
on downstream equipment (e.g. amplifiers).
2. Check that downstream equipment (e.g. amplifiers) is not muted, turned down, or turned off.
Strange soundstage
If the soundstage width is very narrow, check that you have not summed left and right input channels and
routed the sum to the left and right speaker. This will result in a mono signal and hence a narrow soundstage.
If the soundstage is “weird”, check the routing and crossover settings, and make sure that left and right are
consistent. If you are implementing an active speaker, also double check the connections on the rear panel.
Distortion
If your audio playback is distorted, you may have too much gain internal to the DSP.
1. Alter your EQ filters to use cut instead of gain. For example, a low-shelf filter with positive gain and a high-
shelf filter with negative gain are the same filter, but the gain staging is different.
2. Reduce the gain in the input channels of the plugin.
3. If driving with an analog source, reduce the level of the analog signal. (And if necessary, increase master
volume in the miniDSP Flex to compensate.)
