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
Please inspect the active loudspeaker and accessories for completeness and
transport damage after unpacking. Before putting the device into operation,
please read the operating instructions carefully. Keep it as a reference book.
A device that shows mechanical damage or which liquid has entered must not be
connected to the mains.
Use only the supplied power cord. Before connecting to the mains, the power
supply and connection values of the device
(mains voltage, frequency) must be checked. The fuse used in the active
electronics must comply with the factory specifications in the “Technical

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 the 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.
STUDIOART B100 Bass Module
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. 
Without the STUDIOART app proceed as follows:
- Switch on the A100 by pressing and holding
- Switch on B100 on the rear panel using the mains switch – Status LED lights up
- Define A100 as chief loudspeaker: + hold for more than 8 sec – status LED flashes fast first, then slowly and a periodic double beep can be heard
- Defining B100 as connected loudspeaker: hold the pairing button on the back of the subwoofer for approx. 5 sec-status LED blinks
- Wait until both devices have found each other. Then the A100 LED again shows the source with the corresponding LED color and the status LED on the B100 permanently shows the pink LED done
Proceed as follows with the STUDIOART app:
- Switch on the A100 with a long press
- Switch on the B100 on the back with the help of the power switch – Status LED lights up
- Define A100 as the chief loudspeaker: # Call A100 Setup # Select pairing menu # Activate with START pairing # Start connection process with “OK” # Perform step 4 within 60 seconds – Status LED flashes slowly and a periodic double beep can be heard
- Defining B100 as connected loudspeakers: Hold the pairing button on the back of the subwoofer for approx. 5 sec- Status LED flashes
- Wait until both devices have found each other. Then the A100 LED again shows the source with the corresponding LED colour and the status LEDs on the B100 permanently show the pink LED – done.
- End the pairing process with STOP – done
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 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.
FAQs
Status LED does not light up
- Possible causes:
- Power line interruption
- Mains switch in off position (Off)
The automatic switch-on does not work
Possible causes:
The level of the line input is too low. This can occur with music material
with soft passages. Increase the input signal while reducing the volume.
