Features

title

A/B input switcher

The Basswitch IQ DI offers a low impedance input and an input with switchable impedance, both with discrete circuit design. If you connect two instruments to input A and B, the A/B footswitch allows you to toggle between the two. The signal from instrument A is routed to channel A and the signal from instrument B is routed to channel B. If only one instrument is connected to input A, the A/B footswitch routes this signal to channel A or channel B.

title

High-end bass preamp with parametric EQ

Channel A of the Basswitch IQ DI features a high-end preamp and a four-band EQ, designed for bass instruments, offering bass, double semi-parametric mids and treble controls.

title

FX Looper

The Basswitch IQ DI offers two effect loops: a passive serial loop and a switchable, infinitely variable mixing loop that enables you to go from a completely dry signal, through parallel on to serial looping. A phase inverter switch ensures that any out of phase signals do not cancel each other out in parallel mode. And a Tuner Out keeps the tuner out of the signal path.

title

Clean booster

A footswitch and a volume control allow you to add a second high-end amplification stage upstream of the Mix Loop. This allows you to feed tracking or overdrive/distortion pedals with an adequate input signal. If the Mix Loop is not in use, the booster serves as an extremely clean solo booster.

title

DI box

The Basswitch IQ DI bass preamp can be used to send an output signal directly to a mixing console or a recording unit. The high-quality components and features of the Basswitch IQ DI (high-end preamp, ground-switch, pre/post signal-processing switch, pad for output attenuation) in combination with the Lehle True Sound Technology make this bass preamp an excellent DI box, whether you’re using it at a live gig or in the studio.

title

Line mixer

The Basswitch IQ DI can also be used as a line mixer. To do this, the return socket of the Mix Loop is used as input and the ratio of this signal to the signals coming from inputs A and B is adjusted by using the mix control.
