How to change presets on the Memory (DRC required)

The TH quattro can be set with an operational mode for A Channels and an operational mode for B Channels.

Using A Class or Energy Saving mode, these configurations will be automatically set on both channels.

See the following chart:

Example: In a three-way + Sub system, multi-amplified with TH quattro on TW and MID, TH due on WF and

TH uno on SUB, in default setting if you recall memory 1 all of the TH’s would work in Hi-AB Class mode. It is

possible to create custom memories, see for instance the example below, to store in memory 1 a system

especially designed to ensure top quality for each way or to store in memory 2 a system especially designed

for the best power/quality ratio, to store in memory 3 a system set to obtain maximum quality and in memory 4

a system best optimizing the current consumption.

The DRC can manage four customisable memories.

1- Default: In standard configuration, without making any changes, if memory 1 is recalled from the DRC, all the

TH amplifiers connected to the system will be working in Hi-AB Class mode (as it is the default setting), while

selecting memory 2 they will be workin in Hi-Current mode and so on.

2- Customizing: by acting on both the DRC memories and the ASC control panel of the amplifier, you can create

custom setups. For instance, if you want the TH amplifiers to anyway work in A-Class mode, you will have to act

on the setup as follows:

- Select memory 1 on the DRC by pressing first

SEL and then 1

- Select the A-Class preset on the ASC by

accessing to its corresponding setup

- Repeat this operation for each DRC memory

- Repeat this operation for each TH present in

the system
