ADVANCED MANUAL / TH quattro
THESIS
The TH amplifiers ASC unit is the operational interface, programmed to control all of the amplifier’s functions.
The user can interact with the microprocessor which, without interfering with the sound, will provide control for
any possible adjustments. This manual section is especially thought for those who want to get the most of
these amplifiers exclusive features.
Some functions are automatic and transparent to the user, others require support during the installing,
adjusting or modifying phase. By accessing the ASC a set of menus will show, offering specific entries which
the user can operate on:
- Setup Amplifier:
Main Input: the user can decide what kind of source the amplifier has to drive;
Amp ID: the user can name the amplifier identifying the function the amplifier performs inside the system;
ID Preout: the user can name the pre-amplified section so it is possible to manage it inside the system;
X-Over Slope: the user can select the Low-bass filter slope (only in Mono mode);
Dual Power: the user can choose the sound quality and the power the amplifier has to work at;
- Status Monitor: the user can monitor the amplifier working status;
- Runtime Monitor: the user can select it on the Display to intermittently have information on the amplifier
status shown.
Some of these functions need a remote control communicating with the microprocessor. Inside this manual,
where necessary, the presence of the DRC (Digital Remote Control) is underlined. The DRC also adds some
specific functions which you can read on their relative section from page 56 on.
ASC (AMPLIFIER STATUS CONTROLLER)
The TH amplifiers combine an analog and digital section in one device; keeping the two sections on separate
PCBs, although mounted within the same sub chassis.
Each amplifier features a state-of-the-art digital encoding section as well as a 24 bit 192 kHz converter. The
S/PDIF optical input accepts PCM stereo signals; also, the innovation consists in the fact the TH amplifier can
be driven in digital directly and, as a consequence, the whole system too, if a system in multi-amplification
configuration with the re-launch of this digital signal to other Thesis TH amplifiers through the AD Link system
(Audison Digital Link). Each amplifier independently takes care of the D/A conversion. While in the Digital Input
mode the DRC needs to be connected, so it works as an actual general volume and source selector control,
capable of repeating all the low frequency controls (Master Volume, Balance, Fader, Sub Volume).
The AD Link connectors on the TH input panel can receive the digital signal from sources or multi-channel
processors featuring the afore-mentioned outputs (Audison Bit One) and re-launching the digital signal to the
amplifiers chain through a Cat.5 certified shielded cable equipped with an RJ45 connector (provided).
In the following pages of this manual we will explain how to perform the amplifier setup and how to connect it in
all THESIS or mixed chains.
