Testing & Troubleshooting

Testing

Assignment

Test: Remove all audio sources from Aux inputs. Connect an active audio source to the lowest priority input for the current amp/channel. Move the active source through the inputs in the order of priority that was previously set.

Result: The input source should immediately change as the audio source is moved between inputs. If the unit delays in switching between aux inputs then the priority schedule is set differently than expected. Reorder the priorities using ASSIGNMENT.

Input Activity

Test: Set all audio sources so that they are active. Manually select each input (see page 9) and check that the source plays through the amp.

Result: This checks that all used inputs are active. If certain inputs do not play during normal operation, they may not have been assigned to an amp channel. Reassign the input using ASSIGNMENT.

Amp Links - Internal (PM-3180 Only)

Test: Disconnect external audio processing equipment connections.

Result: No output from amps until external equipment is reconnected.

Preset Parameters

Test: Turn unit off and on. Manually select each input assigned for each amp and check VOL, BASS and TREB settings by pushing the function but- tons.

Result: VOL, BASS and TREBLE setting shown in display for the current amp/channel-input combination should be what was expected. If not, enter PRESET (see page 28) and correct settings.

Aux Mute

Test: Make one of the Aux inputs active by turning on only its source. Select an amp and manually select a mic input. Repeat this for all Aux/Mic/Amp combinations of interest.

Result: The active Aux input will play through the amp at the volume set by the AUX MUTE function (see page 33). The level balance between the mic and the muted Aux input can also be checked this way.
