Preliminary operations
Package list
The box contains the following:
1x T Series amplifier.
3x IEC power cords (region specific)
1x Documentation folder
Location
Install your T Series Amplifier in well ventilated rack cabinets.
Secure both front and rear brackets to the rack.
Connect the AC Mains connector to a circuit breaker.
Install the amplifier far from EMF emitting devices.
Avoid placing the amplifier close to heat generating sources.
Cooling
The ventilation openings must not be impeded by any item, keep
a distance of at least 50 cm from the front and rear ventilation
openings of the amplifier.
T Series implements a forced-air cooling system to maintain
constant operating temperatures. Air enters from the front panel,
exiting at the back of the amplifier.
The cooling system features variable-speed DC fans controlled by
the heat sink mounted sensors. This ensures that fan noise and
internal dust accumulation are kept to a minimum.
In the rare case of overheating, the amplifier is protected by limiting
the output power to levels that can be sustained at the actual
ambient temperature.
T Series amplifiers can be stacked one on top of the other, leave one
rack unit empty every four to guarantee adequate air flow.
Cleaning
Use a dry cloth for cleaning the chassis and the front panel. Air filter
cleaning should be scheduled in accordance with the dust levels in
the amplifier's operating environment.
In order to take out the filters remove the 2 front covers by
unscrewing the two T8 Torx screws.
Use compressed air to remove the dust from filters, or wash it with
clean water (let the filters dry thoroughly before reinstalling them).
AC Mains Supply
T Series amplifiers implement a universal switching mode power
supply with power factor correction operating in the range from
100 V
up to 240 V
±10%.
AC
AC
AC mains connection is in the rear panel through the IEC C20 inlet,
the approved power cord is provided.
Connections
Signal Grounding
There is no ground switch or terminal on the T Series amplifier. The
unit's signal grounding system is automatic. In order to limit hum
and/or interference entering the signal path, use balanced input
connections.
In the interests of safety, the unit MUST always operate with
electrical safety earth connected to the chassis via the dedicated
Protective Earth
wire.
Input connections
Two channel version
• 2 x XLR female (Analog input 1, and 2)
• 2 x XLR male (Analog 1 and 2 link output)
Four channel version
• 4 x XLR female (Analog input 1, 2, 3, and 4)
Output connections
Two channel version, right to left:
• 2 x Speakon NL-4 (channel 1+2 and channel 2+n.c.)
Four channel version, right to left:
• 2 x Speakon NL-4 (channel 1+2 and channel 3+4)
4 | T Series
Digital Audio Input connection
Digital input is supported via AES3 (AES/EBU) and Dante™ standard
protocols.
The AES3 input is on a standard Neutrik XLR female. The AES3
connection carries a channel pair through a 110 Ω nominal
impedance wire in the form of a balanced (differential) digital signal:
in AES3 XLR connectors the identification of hot and cold pins is not
an issue; take care to never tie pin 2 or pin 3 (balanced signals) to
pin 1 (ground).
There is also a fault tolerant active repeater for the AES3 input
available on a Neutrik XLR male connector.
T Series amplifiers accept 4 Dante/AES67 channels over two Neutrik
Ethercon connectors. There are three operating modes: 2in x 2out
@ 96kHz (default), 4in x 4out @ 48kHz, 4in x 0out @ 96kHz. Cabling
must comply to TIA/EIA-568-B and adopt the T568B scheme pinout.

amplifiers are automatically discovered and displayed in Dante
Controller with the default identifier: MODELNAME-SERIAL (e.g.
T602-00042069).
Basic Operations
Front Panel
The T Series' front panel features a high brightness 1.8" TFT Color
display, 8 RGB backlit pushbuttons, and a USB port.
Navigating the menu
Get acquainted with the menu structure printed on the foldout
cover of this guide.
When entering the various screens some of the buttons will be lit,
indicating the availability of a usable function.
The 4 buttons closest to the display are used to select the channel(s),
multiple channels can also be selected at once.
When the cogwheel icon
display, pressing and holding the top right botton
will prompt the options menu.

Switching the amplifier On
Once properly powered (power cord inserted, sectioning breaker
closed), if it was ON when it lost power, then the amplifier will turn ON
and pass audio within 10 s.
In order to toggle the amplifier between ON and STANDBY keep
pressed button
for 2 seconds.

Output Mute
Through this page, it is possible to mute each channel independently.
In order to mute a channel (or a pair of bridged/joined channels)
simply press the channel button. The VU meter will be replaced by a
"MUTE" text and the channel pushbutton's color will turn to amber.
Speaker Level
A gain value appears on the screen and the amplifier's CH numbers
are replaced with the speaker's letters.
By pressing the channel button the outputs that are part of the
same speaker are selected, the channel buttons will blink and a
value text is highlighted. Press the edit buttons
