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 VAC up to 240 VAC ±10%. 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)

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. A computer running DanteTM Controller can be used in order to configure audio networking. DanteTM Controller is a software application that manages devices on the network. T Series amplifiers are automatically discovered and displayed in DanteTM Controller with the default identifier: MODELNAME-SERIAL (e.g. T602-00042069).

Basic Operations

LCD BRIGHTNESS: Choose between 3 different display brightness levels.
REMOVE GROUPS: Removes the amplifier from any group, removes also the processing associated with that group. One typical use for this function is to remove any group that is present within the amplifier from any previous operation, while preserving the preset and the snapshot list.
RESET PROCESSING: Reset to the factory default processing parameters (unmuted outputs, straight signal routing, no crossovers, EQ=flat, input to output gain=32dB, no limiters, and delay=0ms).

FW Update%

Updating the firmware can be done through Armonía. During the firmware update, the display will show an “Updating Firmware” message, and a bar will show the progress through the various phases.

Networking

T Series amplifiers support Dante networking. The two-gigabit ports internally connected via a Gigabit switch to simplify wiring and eliminate the need for external network switches in small systems. Control and audio are flowing on both ports. The amplifier can be configured for redundancy using AES3 and/or analog inputs; it can also use a redundant source device on Dante. However, it can’t use two audio networks, so never connect a T Series to the secondary network if there is one in the system.

IP Addressing

Factory default network settings are AUTO IP. STATIC IP policy can also be adopted and configured through ArmoníaPlus or the display panel. Both ArmoníaPlusand the T Series must belong to the same subnet. If a DHCP server is not active within the network, the amplifier platform initiates a stateless address auto-configuration (i.e. Zeroconfiguration networking methodology – Zeroconf): it self-assigns a local numeric network address (of the type 169.254.x.y with a subnet-mask 255.255.0.0) and automatically distributes and resolves the hostnames of the networking devices.

As a rule of thumb, turn the DHCP server on before connecting the amplifiers.

When the amplifier discovers a DHCP server on the network, it negotiates the networking parameters.

ArmoníaPlus System Manager

ArmoníaPlus System Manager is the default interface that allows system setting and customization of the T Series amplifiers. ArmoníaPlus can be installed on a PC running Windows (XP SP3 and higher).
