Sometimes recorded sounds on the Boss BR-8 contain noise or distortion. Incorrect input sensitivity can cause noise. If sensitivity is too high the signal distorts; if it's too low, the recording will be noisy. Using the wrong type of microphone can cause noise in recordings. Some microphones don't produce enough signal and require a preamp before connecting to the unit. Equalizer settings can also cause distortion, so the user should try different settings to fix the problem. When bouncing tracks, noise or distortion can be created if the output level is too high.
The Boss BR-8 saves data to a zip disk, which can sometimes result in data problems. If the power shuts off unexpectedly, like from a power outage, data loss can occur. Sometimes a sudden power failure can actually cause the formatting of the data disk to be lost. If that happens the disk will require reformatting and all stored data will be lost. Physical shock to the disk can also cause data loss; for example, one source of physical shock is applying too much force when inserting the disk.
A number of conditions can lead to no sound from the Boss BR-8. Both the BR-8 and attached equipment must be powered up for sound to be produced. All cables need to be connected correctly and in unbroken condition. Volume controls on the unit and any connected equipment must be set correctly for sound to be heard. If the heel end of the expression pedal is pressed all the way down it will prevent sound from being heard as well.
When connecting an instrument to the Boss BR-8, using a cable that is equipped with a resistor can cause low input volume. A number of conditions can prevent recording. Using any zip disk other than a 100 MB capacity model will prevent recording and recording can't proceed if the disc is full or damaged. Recording to an external digital device requires the external unit to be set to a sampling rate of 44.1 mHz. The external device must also use a standard digital signal format.
