The Basswitch Dual Band Compressor is a high-end compressor in pedal size built especially for bass instruments.

By intelligently linking parameters like attack and release, the amount of controls could be reduced whilst those parameters are dynamically adjusted to the bass-signal. So, operating this device becomes an intuitive, simple and fast act - a clear benefit for live performances.

Equipped with two fully fledged high-end compressors working in two adjustable frequency-ranges, the Basswitch Dual Band Compressor allows effective and harmonious compression of bass signals.

This includes contouring fast staccato-passages, well-defined slapping-lines and a smooth concentration of the sound.


Dual Band Compression with 2 VCA Feed-Forward Compressors

Whether a function similar to a limiter is required or only small peaks are to be be balanced out, the variable compression ratios from 1:1 up to 10:1 create the preconditions for a great variety of sounds. The blue LED shows the intensity of the compression - the harder the two VCA feed forward compressors work, the brighter it glows. The soft knee characteristics we choose allows for a soft, very subtle transition from the uncompressed to the compressed tone.

Adjustable Crossover Frequency and Threshold

Adjustable crossover frequency (250 Hz to 12 kHz) and threshold (-38 dBu to -8 dBu). This dual band flexibility allows in no time to adjust catchy settings, be it for fast staccato passages or for slapping the bass.

Flexible use on Stage and in the Studio

By intelligently linking parameters like attack and release, the amount of necessary controls has been reduced and these parameters are now dynamically adjusted to the bass-signal. So, operating this device becomes intuitive, simple and fast - a clear advantage in a live performances.

Lehle True Sound Technology

Lehle True Sound Technology combines a series of electrical design measures to insure an optimal treatment of the electrical signal of the instrument. The supplied voltage is rectified, filtered, stabilized and brought to 18V. This allows for sufficient headroom even when confronted with strong pickup power peaks. The Lehle buffers effortlessly handle signals reaching the megahertz range. At the output, the frequency bandwidth is limited to the audible frequency range to prevent HF interference. The Lehle True Sound Technology is a key element to the outstanding sonic performance of our products.

Lehle Footswitch on board

The Dual Band Compressor is equipped with a high-quality Lehle footswitch. The load exerted by the foot is absorbed by the actuator button and the housing, preserving the circuit board from mechanical stress. The design is as robust as possibly and the actuator button mounted in a special socket making for easy and silent operation. Inside the Basswitch the impulse from the pushbutton activates special gold-plated relays via discrete logic circuitry. The switching technology and the gold-plated relays in the pedal are designed to operate for up to two million switching cycles!


Buffered-Bypass or True-Bypass? Up to you!

The bypass mode of the Basswitch Dual Band Compressor can easily be changed from Buffered-Bypass, where the device acts as a totally neutral line-driver to True-Bypass, where the input and output are linked with zero losses to one another via a relay with gold-plated contacts.

Q: What is the effect of an impedance converter?

A: The sound will be freshened up and signal loss through long cable runs will be compensated.


Q: How can I compensate the signal loss on my effects board?

A: By using an impedance converter, which provides a high impedance input socket for the instrument signal and a low impedance output signal that is more resistant against loss.


Q: What is Lehle True Sound Technology?

A: Lehle True Sound Technology is based on individual measures that follow one common goal: transporting the sound and character of the instrument in the best way possible, without any negative alteration. It achieves an open and dynamic sound without losing any detail. The buffers are designed to easily transmit within the megahertz-range. The Lehle True Sound technology uses either gold plated relays or gold plated switches, even the smallest currents will be transported without any degradation for many years to come.

What is Lehle true sound technology?

Foot switches are pressed thousands of times during their long lifetimes - sometimes sensitively but some times more brutally depending on the situation and the musician’s temperament. An ordinary footswitch will switch up to 20 000 times before wearing out mechanically or electrically, which means that either it will stop working altogether or the signal will start to lose transparency and dynamics. The Basswitch IQ DI is equipped with high

quality Lehle foot switches. Here the foot of the musician does not press an ordinary footswitch but an actuator button that activates a pushbutton inside the Basswitch IQ DI via a metal lever. Because the actuator button and the internal pushbutton are not directly connected, the load The Lehle transformer allows for galvanic isolation at the D.I. output. Only real physical galvanic isolation guarantees complete elimination of ground hum and annoying background noises in any live or studio situation. The Lehle transformer also offers a high level of safety as it isolates the Basswitch IQ DI from current peaks of up to 2 000 V.


working principle of the Basswitch iQ Di foot switches Lehle transformer

Any effort exerted by the foot is absorbed by the actuator button and the housing, protecting the circuit board from mechanical stress. The design is as robust as possible and the actuator button mounted in a special socket making for easy and silent operation. Inside the Basswitch IQ DI the impulse from the pushbutton activates special gold plated relays via discrete logic circuitry. This way the switching is done only via high-quality relays, thus guaranteeing absolutely reliable and loss free switching of very sensitive signals. The switching technology and the gold plated relays in the Basswitch IQ DI are designed to operate for up to two million switching cycles!

Note: Transformers are widely thought to have a negative impact on sound. This does not apply in the case of the Lehle transformer used in the Basswitch IQ DI. Both the D.I. Out and the Line Out of the Basswitch IQ DI can handle a frequency range from 20 Hz to 100 KHz (linear). The transformer does not affect the headroom

either as levels of up to 16 dBU are handled without a problem.
