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.
