The weakest element of any high-fidelity system is the room. Typical rooms introduce up to 10dB of distortion
in the frequency response. Furthermore, loudspeakers with a perfect impulse response don’t exist.
Trinnov’s ST2-HiFi solves the acoustic equation. It takes your high-end system to a whole new level of
accuracy, from high-fidelity to acoustic-fidelity.

Back side of the microphone
The measurement microphone is one of the most critical
component in the Trinnov calibration procedure.
The Optimizer’s sophisticated algorithms not only rely on very accurate acoustic
measurements but also on the ability to localize speakers positions and to detect early
reflection origin.
The microphone consists of 4 capsules mounted at the top of thin brass tubes to avoid
diffraction.
The capsules form a tetrahedron figure, ideal to identify distance, azimuth and elevation
altogether with a spatial resolution below +/-2° in every direction.
Consequently, capsules are identified from 1 to 4 and the microphone cables are labelled
accordingly.
A led incorporated in the body of the microphone indicates the front of the microphone that
should be pointed at the center of the soundstage before proceeding with a measurement.
Flat response (within +/- 0,1 dB across the 20Hz-24kHz frequency range) is guaranteed by
individual compensation filters.
The microphone uses a standard 9V PP3 LR61 battery to power capsules and electronic.
The second purpose of the frond led is to indicate the battery level.

2.1 TYPICAL CONNECTIONS
The ST2 HiFi seamlessly integrates your hifi installation.
Whether your system allows for series connection and/or insertion loop, both analog and digital inputs/outputs of the ST2 HiFi can be used.

2.2 CONNECTING A SOURCE
The ST2 HiFi allows you to connect and play any stereo source without any configuration.
This example shows how to connect the AES output from a CD player to the ST2 HiFi.

2.4 CONNECTING THE MICROPHONE
Connection of the Microphone
The Trinnov 3D measurement microphone must be connected to the balanced
analog inputs of the ST2 HiFi.
• Always make sure the microphone is turned off before you connect it to the ST2 HiFi.
• The microphone cables are labelled and numbered from 1 to 4.
• Please respect the connection order of the microphone, such as indicated in this figure

3.1 POWERING ON THE ST2 HIFI
To shut the ST2 HiFi down, press the front panel power button once.
The system will need approximately 10 seconds until complete stop.
NOTE It is not recommended to cut the AC Power,
as the system saves several “last-used” settings
while shutting-down.
Turn on the main power switch on the rear panel to supply the ST2 HiFi
with electricity, then press the front panel power button to start the ST2
HiFi. The system takes 45 seconds to initialize.
IMPORTANT NOTE Don't forget that the amplifier
should always be powered up last.

3.2 REMOTE ACCESS TO THE GRAPHICAL USER INTERFACE (GUI)
The ST2 HiFi allows several options for remote control: The ST2 HiFi has built-in Ethernet and optional WiFi.
It can simultaneously be part of a network as:
• a WiFi Access Point (AP) to create its own WiFi network;
• a hard-wired client to join an existing network through an Internet
Service Provider (ISP) Box/Router;
• a WiFi client to join an existing wireless network.
• Remote control from a tablet, laptop or smartphone over the network,
using VNC.
• Telnet command or automation system (Crestron, Savant...)
• Screen, mouse and keyboard directly connected to the PC
IMPORTANT NOTE
The optional WiFi USB dongle must be
connected to a USB 2.0 port (black) of the ST2
HiFi before ignition.

3.3 USING THE ST2 HIFI AS A WIFI ACCESS POINT
Provided that the optional WiFi dongle has been inserted into one of the USB port of the ST2 HiFi before ignition,
a dedicated WiFi Access point should appear in the WiFi Networks list of your tablet/smartphone/computer under
the name "ST2-xx" where xx is the serial number of your ST2 HiFi.
