• A/B input switcher.

The Acouswitch IQ DI offers two high impedance inputs 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. The “MIX” switch located between input A and B allows you to combine and mix both channels.

• High-end acoustic guitar preamp with parametric EQ and body contour control

Channel A of the Acouswitch IQ DI features a high-end preamp and a three-band EQ, designed for acoustic instruments, offering bass, semi-parametric mids with a broad frequency range (100 Hz to 6 kHz) and treble controls. The body contour control acts on both channels.

• FX Looper

The Acouswitch IQ DI offers two effect loops: a passive serial loop and a switchable, infinitely variable mixing loop enabling 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 when in parallel mode. And a Tuner Out keeps the tuner out of the signal path.

• 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.

• DI box

The Acouswitch IQ DI acoustic guitar preamp can be used to send an output signal directly to a mixing console or recording unit. The high-quality components and features of the Acouswitch 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 acoustic guitar preamp an excellent DI box, whether you’re using it at a live gig or in the studio.

• Line mixer

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