Location

Install your TTM Series Amplifier in well ventilated rack cabinets at a maximum height of 2 meters above the floor.
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
Do not block the ventilation openings and allow a distance of at least 50 cm from the front and rear ventilation openings of the amplifier. The TTM Series implements a forced-air cooling system to maintain constant operating temperatures. Air enters from the front panel and exits from 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.
The TTM Series amplifiers can be stacked one on top of the other, but it is recommended to leave one rack unit empty every three amplifiers 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.
To remove the air filter, detach the front metal cover by unscrewing the two T20 Torx screws (visual instructions shown below).
Use compressed air to remove dust from the filter or wash it with clean water (let it dry thoroughly before reinstalling).

AC Mains Supply

The TTM 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 can be found in the rear panel through the IEC C20 inlet. The approved power cord is provided.

Connections
Signal Grounding
There is no ground lift switch or terminal on the TTM Series amplifier. To minimise hum and/or interference entering the signal path, always use balanced input connections. For safety, the unit MUST always operate with the electrical safety earth connected.

Input connections

4x Analog inputs (XLR female)
2x Stereo AES3 inputs (XLR female)
4x Dante/AES67 inputs (EtherCon)

Output connections

4x Amplified outputs (NL4 speakON)
4x Analog Link Out connectors (XLR male)
2x AES3 Link Out connectors (XLR male)
4x Dante/AES67 outputs (EtherCon)

Digital Audio Connection

Digital audio is supported via AES3 (AES/EBU) and Dante™ standard protocols. The AES3 connectors accept input channel pairs through a single balanced XLR cable.
The TTM Series amplifiers offers two Ethercon ports supporting a total of 4-in and 4-out Dante/AES67 channels. Users can configure the amplifier to operate at one of the following three modes: 2-in x 2-out (at 96kHz), 4-in x 4-out (at 48kHz – default), 4-in x 0-out (at 96kHz). This operation is done under the amplifier Dante settings in ArmoníaPlus.
A computer running the software application Dante Controller™ can be used to configure the Dante properties of TTM Series amplifiers, which are automatically discovered and displayed in Dante Controller™ with the default identifier: AMP-XXXXXX, where ‘XXXXXX’ is the MAC address of the Dante interface.

Link Out Connectors
There are in total six Link Out connectors directly connected to the amplifier’s analogue and AES3 inputs.
The four Link Out connectors linked to inputs 1 to 4 are simple passive THRU connections.
The other two Link Out connectors are fault-tolerant active repeaters for the AES3 inputs. When the amplifier is on, they actively repeat the AES3 input signal. If power is lost, an internal relay is switched causing these connectors to work as simple passive THRU connections.

Basic Operations

Switching the amplifier On
To turn on the amplifier, simply connect it to the mains power with the provided power cord. The time between power on and passing audio is under 10s for analogue sources. Time is longer with Dante sources (about 22 seconds), as the network is rebooted and patching remade. Once the device is on, it is possible to manually put it in standby mode. Further information is detailed below in a dedicated section called ‘Power Off’.

Front Panel Controls
The front panel comprises a multitouch capacitive display (1), a rotary encoder with pushbutton (3), a power status LED (4), and a ‘Back/ArmoníaPlus Callback pushbutton (5).
Users can select what parameters to control and navigate through the different display options and pages available, by touching the screen, rotating and pushing the rotary encoder, or pushing the ‘Back’ button. Control of some specific parameters, such as output level and delay, are only possible by rotating the encoder.
From the main menu (2), it is possible to access all the different pages from where control operations can be performed.

VOID Bias Q3 Touring Power Amplifier-7

Home
The Home page displays the amplifier’s output channels, their level, and the speaker presets assigned to them. From this page, it is also possible to mute/unmute the outputs by clicking the respective loudspeaker icons .

Level & Delay
The Level and Delay pages allow the control of the amplifier output levels and delay times. Once in one of the two pages, click on any given output and adjust the level or delay by turning the rotary encoder. When an output is selected, the white LED behind the encoder will light up, indicating that the parameter can be altered. Note that it is possible to select multiple outputs at the same time and simultaneously control their relative levels and delay. Selected outputs will display a check mark ✓ next to the speaker preset name.

Clicking the ‘Set Step Size’ button on the top of the display, allows the selection of the change steps to be applied when rotating the encoder, if finer adjustments are necessary. Level change steps can be set from 1dB (default) to 0.1dB, while delay steps can be from 10ms to 0.1ms (default is 1ms). For the delay controls, it is also possible to select between metric (m) or imperial (ft) systems.

Matrix
The TTM amplifier series has an internal 4 x 4 mixing matrix. The Matrix page shows the internal matrix outputs and the matrix inputs that are routed to them. It is possible to change the routing by clicking on one of the ‘INPUT’ labels and selecting a new input from the list. These can be any of the four matrix inputs, or a mix of input channels 1 + 2, or channels 3 + 4.

Other routing and mixing configurations can be achieved from ArmoníaPlus. In such cases, the TTM will display ‘CUSTOM’ in the input label.

Source Select
The Source page shows what amplifier input sources are active in each of the 4 internal matrix inputs. These sources can be any of the 4 amplifier analogue inputs, AES3, or Dante inputs. Manual selection of different sources, as well as configuration of an automatic backup selection based on signal presence, can be achieved from ArmoníaPlus.

Snapshots
Snapshots are full amplifier configurations that can be saved onboard of the device, and later recalled when necessary. In the Snapshots page, it is possible to load up to 50 different amplifier configurations that have been previously saved onboard using ArmoníaPlus. To load a new snapshot to the amplifier, scroll through the list, select one of the snapshots available, and click the ‘Load’ button at the bottom of the screen.

Out Config
The Out Config page allows quickly bridging the amplifier’s outputs 1 and 2, and/or outputs 3 and 4. Simply click the ‘Bridge’ button to perform the operation, and ‘Unbridge’ to revert to the default configuration.
When n-way loudspeaker presets have been load to n-speaker channels, a new button labelled ‘Split’ will show up in this page. It is possible to split the ways for individual configuration and control by clicking this button.

Speaker Preset
From the Speaker Preset page, it is possible to load different loudspeaker presets to the amplifier’s outputs. To load a new preset, click the gear icon , and scroll through the different families, models, and speaker applications. If the preset has been successfully loaded to the output channel, its name will show in the Speaker Preset page.

Net Config
The Net Config page displays the settings for the amplifier control and Dante network configurations. To scroll between the amplifier and Dante settings, use the arrows ►. Clicking the gear icon , in one of the two pages, opens the IP configurations, from where it is possible to set the amplifier or the Dante network to Auto (default) or Static IP, and reset the network configurations to the default settings.

Node Info
The Node Info page displays general amplifier information, such as its serial number, operating temperature and mains voltage, firmware versions, and ethercon ports configuration.

From this page it is also possible to access some additional amplifier settings by clicking the gear icon . These settings are as follows: Lock LCD – allows the user to set a password and subsequently locks the front panel display. When trying to perform any operation, the user will be requested to insert the password to unlock the screen. Remove Groups – removes the amplifier from all EQ groups that have been previously created using ArmoníaPlus. Group EQ settings will be lost under this operation.
Factory Default – sets the amplifier to the factory default settings. Snapshots saved onboard are not deleted.
LCD Brightness – adjusts the brightness of the front panel display. Auto Fade – allows different screen on/off options, where ‘Always On’ never turns the screen off, ‘Auto Fade’ causes the screen to operate at lower brightness after 30s of not being used, and ‘Auto Off’ causes the screen to automatically turn off after 30s of not being used. A simple touch to the screen brings it back to its normal operation status.

Power OFF
From the Power Off page, it is possible to manually put the amplifier in standby mode by clicking the ‘Power OFF’ button. Pushing and holding the rotary encoder for 4s also triggers the standby mode. The power status LED (4) is green when the amplifier is ON and becomes red when the amplifier is in standby mode.
Once the amplifier is in standby, to turn it back on, simply touch the screen or push the rotary encoder, and select ‘Power ON’.

FW Update
Amplifier and Dante firmware updates can be performed via ArmoníaPlus. During the firmware update, the display will show the message ‘Updating Firmware’, and a status bar will show the progress through the various phases.

Networking
The TTM Series amplifier supports Dante networking. The two-gigabit ports are internally connected via a Gigabit switch to simplify wiring and eliminate the need for external network switches in small systems. Control and Dante audio are available in both ports by default. This configuration can be checked from the front panel screen under Node Info > ETH 1/ETH2.
Note: the TTM does not support Dante redundancy, therefore, do never connect the two ethercon ports to separate primary and secondary Dante networks simultaneously.

IP Addressing
The factory default network configuration is AUTO IP/DHCP.
STATIC IP policy can also be adopted and configured through ArmoníaPlus or the screen panel (see ‘Net Config’ section).
If a DHCP server is not active in the network, the amplifier platform initiates an auto-configuration with a local numeric network address (of the type 169.254.X.Y and subnet mask 255.255.0.0).
It is recommended to always turn on the DHCP server before connecting the amplifiers.

ArmoníaPlus System Design
ArmoníaPlus System Manager is the default interface that allows setting and customisation of the TTM Series amplifiers. Note that whenever the TTM is connected to ArmoníaPlus, the front panel display operations are disabled.
ArmoníaPlus can be installed on a PC running Windows (XP SP3 and higher).
For a successful connection, both ArmoníaPlus and the TTM Series must belong to the same subnet.
