Representing a high-end solution, the simplicity and power of the analog system found in the HV venti is thrust

forward again in the TH, making use of the amplifiers versatility.

The crossover ONLY acts on the amplifier power output, not on the PRE OUT output which is always a bypass.

The alignment is a Butterworth type as, when either of the TH amplifiers is set up in a mono configuration, the

slope of the filter can be set for 24 dB Oct operation.

Each TH quattro is factory provided with:

- a pair TH-MXR.1 crossover board, containing the electronics required to set, through selectors, the operation

mode as well as the Low-Pass filter slope.

- two pair of eight crossover modules each, featuring high-precision resistor packs corresponding to 32 cut-off

frequencies placed at equal distance from 18Hz thru 7,5kHz.

- four customisable crossover modules (to build them, see the “Custom Module” section in this manual).
