Troubleshooting

If the BR-864 does not function as you expect, please check the following points before assuming that a malfunction has occurred.

If this does not resolve the problem, contact a nearby Roland service center or your dealer.

Problems with the sound

No sound

Is the power of the BR-864 and of the connected equipment turned on?

Are the audio cables connected correctly?

Are any audio cables broken?

Has the volume of the connected amp or mixer been lowered?

Has the MASTER fader or headphone volume of the BR-864 been lowered?

Is a memory card inserted?

Has the wrong card been inserted?

You can use commercially available CompactFlash cards as memory cards for the BR-864; The 3.3 V type with the capacities of 32 MB to 1 GB can be used.

Are you attempting to play back a short phrase of less than 1.0 seconds? Phrases of 1.0 seconds or less cannot be played.

The volume level of the instrument connected to GUITAR/BASS jack or LINE IN jack is too low

Could you be using a connection cable that contains a resistor?

Use a connection cable that does not contain a resistor.

A specific track cannot be heard

Has the track volume been lowered?

Is the V-Track setting for a different V-Track?

Has the track been muted?

The input source cannot be heard

Did you adjust the SENS knob?

Has INPUT SELECT been muted? (The INPUT SELECT indicator will be dark.)

Has the INPUT LEVEL knob been set to “MIN”?

If you are using the internal microphone, is “Built Mic” under UTILITY set to ON?

Cannot record

Is a song protected?

Is a memory card inserted?

Does the memory card have insufficient remaining capacity?

Has the recording mode (REC MODE) been selected correctly?

Has the Phrase Trainer or Scrub Playback function been turned on?

The recorded sound contains noise or distortion

Is the input sensitivity set appropriately?

If the input sensitivity is too high, the recorded sound will be distorted. If it is too low, the input sound will be buried in noise. Adjust the SENS knob so that the level meter moves as much as possible without causing the PEAK indicator to light.

*Set it so the “0” is not indicated in the level meter.

Are the track output levels appropriate?

If you hear noise or distortion after bouncing tracks, the output level of the tracks was too high.

Is a mic with high output impedance connected directly to the BR-864?

The BR-864 is designed with a wide margin of headroom. Also, since the MIC jacks are low impedance

inputs (TRS type: 8.9 kΩ , XLR type: 8.2 kΩ (Hot-Cold)), the recording level may be too low, depending on the response of some mics. In such cases, connect the mic via a mic preamp to the BR-864, so that they can be boosted to line level before recording.

Cannot digitally record to an external device

Does the sampling rate of the BR-8 match that of the digital audio device?

Set the digital audio device to a sampling rate of 44.1 kHz.

Does the digital signal format match?

Your digital audio device may use a non-standard digital signal format. Connect the BR-864 to a digital audio device that supports CP-1201 or S/P DIF.
