Boss Audio Systems BR-900CD User Manual

The BR-900CD is designed to be operated as easily as a 
cassette tape recorder, even by beginners.

The BR-900CD allows anyone to readily enjoy the benefits of 
digital recording as soon as it’s taken out of the box. So, 
you’ll surely have listened to the demo songs, if not gone 
ahead and produced an entire audio CD, all on your first day 
with your new unit.

In addition, it comes equipped with a CD-R/RW drive, 
making it easy to keep recorded works stored on audio CDs.

In addition to a digital mixer and digital recorder, the BR-
900CD contains five digital effects processors.

It is possible to perform all steps needed for recording, including 
editing, bouncing tracks, using effects, and mixing down, 
entirely within the digital realm, so there is no deterioration in 
the signal quality.

Using the USB connector also allows you to save the song 
data you create to a computer.

The BR-900CD has eight audio recording tracks, which 
provides for simultaneous recording on two tracks, or 
simultaneous playback from eight tracks.

Moreover, each track incorporates eight virtual tracks, called 
“V-Tracks,” for a total recording capability of 8 x 8 = 64 
tracks! This increased versatility allows you to do things such 
as record numerous takes of a guitar solo, which you can 
later choose from when putting it all together. Also, while 
playing back eight tracks, you can use the bounce mode to 
bounce to a V-Track and perform stereo bouncing without 
needing to erase any data.

The BR-900CD features a CD-R/RW drive capable of both 
reading and burning CD-R and CD-RW discs, making it easy 
to produce audio CDs of the performances you record.

In addition, you can back up performance data stored on 
memory cards to CD-R/RW discs for even more efficient and 
effective use of your memory cards.

The “Rhythm function” makes it easy to capture phrases or 
musical ideas that come to mind. Simply select an 
appropriate Rhythm pattern, and set the tempo.

In addition to the internal preset Rhythm patterns already 
provided, you can also create your own original Rhythm 
patterns. By recording using the Rhythm function, editing 
one measure at a time is greatly simplified.

The BR-900CD comes with five different types of effects 
processors. These systems, including recording effects (Insert 
effects), send/return (Loop Effects), tone adjustment (Track 
EQ), vocal pitch correction (Pitch Correction), and mastering 
effects (Mastering Tool Kit) can be used independently for 
each application as needed. This enables high-quality song 
production in a single device, with no need to connect any 
external effects.

The BR-900CD has many built-in simulations and effects, 
including amp modeling with COSM for a wide variety of 
insert effects. Many effects for vocal, keyboard, and guitar 
tracks are also included for a vast array of applications. 

The loop effects include spatial effects such as chorus and 
reverb, which are vital for proper stereo mixdown.

The Track EQ is a built-in, two-band EQ whose utility is most 
fully exhibited in making tone adjustments during mixdown.

Each track consists of eight virtual tracks, and you can 
choose any one of these tracks for recording or playback. 
This means that you can record to up to a maximum of 
64 tracks, and then select any eight of them to play back. 
These virtual tracks that make up the actual tracks are 
called “V-Tracks.”
