Introduction
Congratulations on your purchase of the new STUDIOART B100 Bass Module and thank you for your trust in our high quality
products.
To enjoy excellent sound quality in your home, carefully read the following instructions before first-time operation.
General safety instructions, disposal of your old device and warranty conditions can be found in the enclosed leaflet.
Unpacking
We recommend that you keep the packaging material for later transport.
Features
The Revox STUDIOART B100 Bass Module is a bass speaker designed for free placement on the floor. A built-in, high-quality
amplifier drives a specially developed 20 cm long-stroke bass driver, which is located in a dual port bass reflex enclosure. The
radiation is downwards. The sound is emitted via the defined, circumferential gap between the bottom of the housing and the
floor. The amplifier electronics include a subsonic filter that prevents damaging membrane excursions, especially at very low
(subsonic) frequencies. In addition, the B100 has a soft-clipping function, which gently adjusts the output power back to the
power limit when overloaded, so that no audible distortion or interruptions can occur.
The STUDIOART series was developed for use with high-quality stereo and home cinema systems.
Commissioning

Connector panel
Power switch: On / Off
The unit can be completely disconnected from the power supply via the power switch – there is no power consumption in the
off position (off).
Overvoltage / lightning strike
The off position does not protect against damage caused by overvoltage or lightning strikes. In thunderstorms, please unplug
the power cord.
Status indicator LED
: B100 is in standby and needs about 0.9 watts.
: B100 is on - no pairing with STUDIOART products
permanent: B100 is wirelessly connected to a STUDIOART product
flashing: B100 is ready to pair with a STUDIOART product
Mains input jack (AC)
Use only the supplied power cord. The B100 is equipped with a multi-range power supply that covers AC voltages of 100-240
VAC (50/60 Hz).
Volume control
Volume adjustment. In order to ensure a good signal-to-noise ratio and response of the automatic switch-on, it makes sense to
select a high input level and accordingly to reduce the gain (volume control).
Note: When connected wirelessly to other STUDIOART products, the volume control has no function.
Crossover frequency control (line input)
Infinitely variable low-pass filter with a crossover frequency between 40 - 200 Hz. The higher the frequency selected, the
greater the maneuverability of the B100. In order to get a perfect, sonic match between the B100 subwoofer and the satellite
speakers, the upper cut-off frequency (frequency at which the bass level drops) should be chosen so that there is no overshoot
in the takeover range between B100 and the satellite speakers. Turned clockwise, the takeover frequency increases towards the
satellites. Correspondingly, conversely, the frequency range in which the B100 operates decreases.
Note: When connected wirelessly to other STUDIOART products, the frequency control has no function. The transfer frequency
is automatically set by the STUDIOART system.
Phase control 0 ° - 180 °
With the phase control, you can turn the subwoofer signal in the phase from 0 ° to 180 °. This can be used to improve bass
response in the listening position in relation to the other speakers, depending on the location.
Note: When connected wirelessly with other STUDIOART products, the phase control has no function.

Pairing Button
The B100 can connect to other STUDIOART products wirelessly. The B100 connects with a main loudspeaker e.g. a STUDIOART
A100. Pairing two speakers is done through a one-time pairing process, where the main speaker is set as "Master", the B100 as
"Client".
Line input (L / R)
The B100 bass module can also be connected via cable to any stereo or home theater amplifier that has a preamp / subwoofer
output outside the STUDIOART series; e.g. with a Revox Joy Receiver S119 or S120.

How do I connect the B100 Bass Module?
The STUDIOART B100 Bass Module has been designed to be used as a subwoofer in high quality stereo and home theater
systems and can be connected to your music system in two different ways:
Wireless connection to other STUDIOART products, e.g. the A100 Room Speaker
Cable connection (RCA stereo) with any stereo or home cinema amplifier with preamp / LEF output
Wireless connection between B100 and other STUDIOART products
The B100 can be wirelessly connected to the STUDIOART A100 Room Speaker and supports it in the low-frequency bass range.
To make this wireless connection clear, both speakers, the B100 as a client and the A100 as the chief, must be made known
through a one-time pairing process. How to do this can be found on the next page of this quick guide or in the user manual of
the STUDIOART A100 Room Speaker, which is available for download at www.studioart-revox.com.
Important note
If there is a radio connection, the cut-off frequency is automatically set by the STUDIOART system. The settings for volume
(amplification) and phase are only adjusted in the STUDIOART App for audio impression. The three knobs on the back of the
B100 are without function in this case!
The volume, crossover and phase controls are only active if the B100 is supplied with a subwoofer signal via cinch cable and
there is no radio connection to other STUDIOART products - see Wiring connection.
Example wireless connection B100 with stereo set A100
The main A100 loudspeaker Chief requires a connection to the domestic network (WLAN / LAN). The individual STUDIOART
loudspeakers communicate with each other via their own, uncompressed wireless network (KleerNet ™). Due to the low radio
power, this radio network is designed only for connections within a room.
Alternatively, a wired P100 passive speaker can be used for the A100 Client.

Connect B100 Bass Modules via radio to A100
When pairing, an A100 is defined first, either directly on the device or via the STUDIOART App, as the chief speaker. Then you
do the pairing process on the B100 Bass Module itself. After successful pairing, the B100 will be listed as a paired Speaker in the
STUDIOART app and can be further configured there.
Distance: For the pairing process, the A100 and the B100 should be no further than 2 m apart. In later operation, the
distance between A100 and B100 may be up to 10 m, provided there are no strong sources of interference such as
repeaters, micro sources, baby monitors, etc. active in the area. From an acoustic point of view, however, the
distance between A100 and B100 should be kept as small as possible.

Cable connection between B100 and stereo / home theater amplifiers Line input (L / R)
The B100 bass module can also be connected via cable to any stereo or home theater amplifier that has a preamp / subwoofer
output outside the STUDIOART series; e.g. with a Revox Joy Receiver S119 or S120.
Classic stereo amplifiers with a stereo preamp output, connect to a 1: 1 RCA cable. The cut-off frequency up to which the
B100 should support the other loudspeakers in the bass range is set on the B100. Phase and volume can also be adjusted
using the rotary controls.
For home cinema amplifiers with an explicit subwoofer output (LFE signal), a Y adapter is required, which splits the single-
channel signal into the two B100 inputs [Line Input R + L]. Here, the home theater amplifier usually determines the crossover
frequency. Therefore, in this case, the cut-off frequency should be set to the maximum of 200 Hz and the phase to 0 °. The
volume can be adjusted using the rotary control.
The line input is equipped with signal detection, which automatically turns on the B100 as soon as a music signal is present. If
no input signal is detected for more than approx. 20 minutes, the B100 subwoofer automatically switches back to standby mode
(standby consumption <0.5 W).
Note:
The automatic switch-on is level dependent, i.e. at very low signal levels, it may happen that the B100 subwoofer is not turned
on or turned off too early. If necessary, increase the input signal while reducing the volume.

Placement
Very low frequencies, as emitted by the B100, are very difficult to locate. The aim is therefore to integrate the B100 so that it is
not perceived superficially, but rather extends the sound image positively with respect to the lower frequencies.
To achieve this, Revox recommends considering the following points:
•Experience has shown that a more homogeneous sound is created when the subwoofer is placed in the area of the
main speakers or between them.
•When installed in the corner of a room, it may result in undesirable elevation of individual low bass frequencies. The
closer the B100 is moved towards the wall or room corner, the stronger, but also less precise, the bass reproduction
becomes. The bass response shifts towards a "slimmer, drier" bass due to a greater distance.
•The STUDIOART B100 does not need to have visual contact with the listener/ listening position.
The low-frequency behavior can be fine-tuned with the aid of the volume and the phase position after a good installation site
has been found. In the case of a wired connection, the takeover frequency can also be adapted.
Load capacity
The woofer is tuned to the output power of the built-in amplifier. Nevertheless, extreme situations can cause overloading with
very long lasting, abnormal signals, i.e. no music signals (generator or other test signals) and at full volume. In general, it should
be noted that the volume is increased only until the ear - mostly reliable - reports an overload. This sign is expressed in a timely
manner by a very strong growth of distortions in the sound image. A short-term overload (30 sec.) will not damage your Revox
speaker. If the loudspeaker driver has been damaged due to overloading, this can be clearly determined by the responsible
service technician. In this case, a warranty service by Revox is not granted.
Care
The real glass surface of the B100 can be cleaned with a mild window cleaning agent. In contrast, the painted housing surfaces
should only be cleaned with a damp cloth and then rubbed dry with a soft cloth. Never use cleaning agents with grinding
additives.
