Using The Subwoofer - Devine RX Series User Manual

Using the Subwoofer

The RX-10SA studio subwoofer is a great addition to a pair of RX studio monitors but also works well with
monitors from other manufacturers. By using this subwoofer, it's possible to get an honest and accurate
representation of the lower frequencies in your productions. The subwoofer is designed to produce subtly
present lows, but can also be used to add more bass to casual listening sessions, combined with a set of RX
monitors and connected to a computer or television, or as a DJ console expansion.
The RX-10SA is designed to work alongside a pair of studio monitors and to take over the processing and
production of any low frequencies in the audio signal. Thanks to a variable crossover, you can set the cut-off
limit anywhere between 50 Hz and120 Hz. Any frequencies above the set crossover point are then sent to
the speakers, while the frequencies below the limit are handled by the subwoofer to give the speakers more
headroom, improving their performance.
Subwoofers like these are ideally used in larger rooms and as an addition to a pair of regular monitors.
Warning Before Use
The Devine RX subwoofers are capable of producing volume levels that can cause temporary or permanent
hearing damage. Use these units with care and keep the volume at a reasonable level when possible. The
volume should ideally be set to a comfortable level when listening to music.
Devine cannot be held liable for any injuries or damage resulting from the use of this product.
Connecting the Subwoofer
The Devine RX-10SA is ideally placed somewhere on the floor, but preferably not in a (far) corner to prevent
dense sound effects. A tight sound is what's usually desired. Try out different positions in the room with a
basic set-up that can be easily moved around. The response of the room, the acoustics, can have a huge
effect on the sound and how much bass is ultimately shaped. Feel free to experiment with the settings to find
what best suits the situation.
If possible, use balanced cables and connections. In general, XLR cables and TRS jack cables (can be
recognised by the tip, ring and sleeve) are what's used in a professional set-up, where the subwoofer is
combined with a DJ mixer/console or an audio interface.
It's also possible to use unbalanced cables, in this case, RCA and TS jack cables. But bear in mind that
unbalanced signals require more amplification power and are more sensitive to external factors, which
increases the risk of interference and noise.
Audio Technology and Set-Up
Sound Sources, Interface & DAC
Once your studio monitors are in the right position, it's important to use a good-quality sound source for the
best possible results. This includes audio files that, ideally, should be the best-quality original material and
not converted files.
The hardware used to play audio should also be the best quality possible. When playing files via a computer
(PC or laptop) or a mobile device (smartphone, recorder or tablet), it's a good idea to use an audio interface
or DAC (Digital to Analogue Converter) that will convert digital files into an analogue signal while retaining as
much of the original quality as possible. Built-in sound cards, especially cheaper models and those found in
mobile devices tend to have a negative influence on the sound.
The audio interface or DAC you use should preferably have a relatively high output with plenty of headroom
to prevent problems with distortion and ensure the audio signal reaches your monitors at a sufficient volume
without the need for much extra amplification. Any extra amplification that's required can have a negative
influence on the audio signal.
