NOVA TX 10
۵۶۹,۵۱۰,۰۰۰ تومان
The NOVA.Net „System Engineer“ PC app is much more than just a remote control panel for a TX amplifier. The PC app and any
connected device(s) become intimately intertwined, faithfully duplicating any control adjustments whether they are made in
the application or on the front panel of the device itself. Adjust a gain control on the device, and watch the gain value in the
app smoothly slide in sympathy. Each input and each output can be named in the application. These names not only appear
for the user on the application control panels, but also show when scrolling through the inputs and outputs on the device
itself. Even a firmware update can be made easily via the network.
High Speed Interface
The TX amplifiers include a high speed ethernet communications interface that supports DHCP, static-IP and
auto-IP and direct connection to a computer without the need for a router or a switch.
AES3 and Digital Networked Audio
The TX amplifiers offer a dual channel AES3 input as standard. The DANTE audio
networking card is available as option.
Drive Module Concept
The powerful drive module concept allows for abstraction from device centric to speaker based control. The TX10 and TX20 use drive module presets, which are defined as a number of outputs driven from one DSP input. This system allows for better flexibility and greater functionality when loading and storing presets. Drive modules allow for a less processor-centric and more speakerorientated system design. The TX amplifiers allow 50 drive module presets to be stored. Presets are stored permanently inside the amplifiers and so will always be available even if the devices are not being used with the NOVA.Net software.

Protection Systems
Under all circumstances the control and protection systems will endeavour to deliver the maximum power possible for a given set of conditions, applying limiters only in extreme circumstances.
Muting will only occur when a dangerous situation is detected, normal operation automatically resuming when the condition clears. An inbuilt notification system is provided to indicate
problems to remote devices either via the network or the volt‐free changeover relay contacts accessible on the rear panel.
System protection
• Excessive power supply current or amplifier output current
• Excessive temperature per sub system: PSU, amplifier and DSP
• Mains voltage within acceptable limits
• Internal power rails producing correct output
• Fans operating at correct speed
Power distribution protection systems
• Mains inrush current limiting for soft start and anti‐surge
• Mains average current limiting for mains breaker management
• Randomised initialisation when remotely powered up
Monitoring, measurements recorded against time
• Supply current
• Supply voltage
• Thermal capacity
• Each driver current
• Each driver impedance
• Protection
• Limiting for each output
Speaker protection
• Sustained clipping prevention
• DC offset protection
• Excessive HF energy (VHF) limiter
VX audio output limiters
Vx provides a linear phase virtual crossover and two limiter paths on each output.
This unique system delivers effective protection for systems that incorporate
passive crossovers.
Vx Limit: Multiband peak limiter, two per output
Vx Max: Multiband overshoot limiter, two per output
X‐Max: Driver excursion limiter
T‐Max: Driver thermal limiter (long term power limiter)
