REVOX B100 Bass Module

Connection 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.

•  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

How do I connect the B100 Bass Module?

The STUDIO ART 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 STUDIO ART products, e.g. the A100 Room SpeakerCable 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 The 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.

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. Update The B100 Bass Module requires the small Windows program B100Updater.exefor an update, which can be downloaded free of charge from www.revox.com.For the update, the B100 is connected to a Windows PC with a USB cable (USB-A to USB micro).

How do I connect the B100 Bass Module?

Example wireless connection B100 with stereo set A100The 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

WITHOUT the STUDIOART app proceed as follows:

1.  Switch on the A100, switch on the B100 using the mains switch on the rear panel – Status LED lights up
2.  Define A100 as master loudspeaker: hold + for more than 8 sec – status LED flashes fast first, then slowly
3. Defining B100 as paired loudspeaker: hold the pairing button blinks on the back of the subwoofer for approx. 5 sec-status LED
4.  Wait until botha devices have discovered each other. The A100 (Chief) LED will now show the source with the corresponding LED colour and the status LED on the B100 will permanently display the pink LED – done.

Proceed as follows WITH the STUDIOART app:

1.  Switch on the A100, switch on the B100using the mains switch on the rear panel – Status LED lights up
2.  Define A100 as the master loudspeaker: #Call A100 Setup # Select pairing menu # Activate with START pairing # Start connection process # Perform step 4 within 60 seconds – Status LED flashes slowly
3. Defining B100 as paired loudspeaker: Hold the pairing button LED flashes on the back of the subwoofer for approx. 5 secs – Status

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.

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.
