01-Gold-RS.jpg Gold-plated Relays & Switches
The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts need to be made of special materials to permit loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.
02-4-band-EQ-double-parametric-mids.jpg 4-band EQ with double semi-parametric mids
An EQ is primarily intended to raise particularly desirable frequencies in a sound spectrum as well as filtering out the undesired ones. By semi-parametric filtering, and the division in HM for high and LM for low mids, a very individual and precise adjustment of the sound is possible.
The T-knob, a so-called shelving filter, controls the heights, the B-controller is responsible for the basses. The center frequency is selected with HF and LF and with HM and LM you can determine the intensity. Thus these frequencies can be raised or lowered in a bell-shaped curve.
03-18V.jpg Voltage Internally Doubled to 18V
To exploit the dynamics of tube amplifiers to the full, the input voltage of Lehle products bearing this symbol is rectified from the power supply socket, then filtered, stabilized and doubled to 18V.
05-Gain.jpg Adjustable Gain
Adjustment of volume or distortion using a gain controller is a vital feature in many situations. The gain controllers on the corresponding Lehle products feature black anodized aluminium knobs set back into the housing so that they can be easily fingertip rotated but keep their settings during performances and transportation.
08-LTMZ.jpg Lehle LTMZ Transfomer
The Lehle LTMZ transformer allows the galvanic isolation at the DI output. Only real physical galvanic isolation guarantees complete elimination of ground hum and annoying background noises in any live or studio situation. The Lehle LTMZ transformer also offers a high level of safety as it isolates from voltage peaks of up to 2000V - without loosing any tone!
09-XLR.jpg XLR Output
Equipped with a standard male XLR-socket with gold plated contacts for balanced output.
The concept for this "swiss army knife for bassplayers" comes from Jacques Ruppert, head of RMI, while the technical part was realized here at Lehle. As a central controller for bass setups it is equipped with a number or features:
  • Lehle True Sound Technology
  • Input A/B switch with impedance matching for piezo pickups
  • Studiograde preamp
  • 4-band EQ with double semiparametric mids
  • switchable effectsloop with blend/mix control
  • switchable effectsloop can also be used as volume boost
  • serial effectsloop (non switchable)
  • Studiograde D.I.-box with Pad-, Pre/Post- und groundlift-switch incl Lehle LTMZ transformer for galvanic isolation
  • can be used with any power supply 9 to 20 volt AC oder DC
  • additonal output for tuner
  • muteswitch
  • extremly robust design with protected controls
The Basswitch IQ DI is manufactured by Lehle in Germany on behalf of RMI.
