Control bass levels easily from anywhere inside your car
Designed for use with JBL® MS Series amplifiers, the MS-WBC wireless bass control lets you precisely raise or lower the bass output of your car audio system – without altering the character of the sound. Conventional bass controls work by changing the system’s crossover frequency, which affects overall frequency response. But the MS-WBC lets you dial bass output up or down by up to 10 dB without changing frequency response. An RF remote that installs in minutes with just a screwdriver, the MS-WBC works with all the MS amps in your system, letting you set the perfect amount of bass for any recording or source.
The MS-WBC is a radio-frequency (RF) device that communicates wirelessly with one or more compatible JBL amplifiers to control levels of bass boost. It is configured to the amplifier in a pairing process similar to the way in which mobile phones and headsets are paired. Every time the audio system turns on, each amplifier that’s been configured to the MS-WBC recognizes it instantly. Since there are no wires to connect, you can place the control wherever it’s most convenient.
You can easily pair the MS-WBC with a quick 15-second (or less) setup and then synchronize it to multiple amplifiers so that a single MS-WBC adjustment makes all amplifiers provide the same level and speed of bass boost. The MS-WBC is compatible with all JBL MS Series car audio amplifiers.
Where other systems simply boost the entire audio bandwidth covered in that amplifier channel, the MS-WBC recognizes that the low-pass crossover point must remain constant. Subwoofers do not sound great when they’re crossed over at 200Hz, which effectively is what happens in most other bass-boost designs. But this unit shelves the bass boost and provides a linear “lift” to all frequencies below the boost cutoff. The result is better overall balance of sub bass and a better transition between the subwoofer and other speakers.
It’s a snap to install the MS-WBC because it has no wires to connect. Installation hardware and adhesive pad are included with the unit; it even comes with a screwdriver. The unit derives its power from an onboard, wafer-style, 3-volt CR2025 battery. Or, in a maintenance-free installation, you can connect the unit to your car’s electrical system.
Since it is paired to your amplifier(s), the MS-WBC knows when it needs to “wake up.” It responds and uses power only when an audio system is playing. As a result, the unit’s internal battery can last a very long time.
The MS-WBC is active only while an audio system is on. It will not make adjustments inadvertently when the system is off, which ensures that no unauthorized hands can change its bass-boost level. Once the system powers back up, the bass-boost level resumes exactly where it was before the system turned off.
The MS-WBC is battery powered, but we’ve included an optional two-wire plug to allow professional installation at a hard-wired power source. Simply connect the two wires in the plug to chassis ground and to a switched or constant +12-volt DC source.
