Torus Power AVR ELITE SERIES Overview
Torus Power AVR ELITE models deliver clean AC power with noise attenuation from 2 KHz to beyond 1 MHz. They
provide true isolation (using large toroidal transformers) along with low source impedance and high
instantaneous current for today’s most sophisticated and powerful audio amplifiers. The performance level is far
beyond what any typical power conditioner using discrete filters can provide.
Torus Power AVR ELITE series products are full-feature state-of-the art power transformers and voltage
stabilizers, with a built-in web browser interface for Local Area Network and Cloud based connectivity for
monitoring and control of audio/video systems. It is not necessary to use either as the AVR ELITE provides all the
standard features, performance, and benefits right out of the box.
The AVR ELITE series provides multiple output zones that can be separately turned on or off through the web
browser or via user defined schedules. A key feature is the voltage stabilization that keeps an optimal output
voltage range (North America models +/- 4V, Europe/Asia/Australia +/- 8V of nominal operating voltage)
regardless of fluctuations in the line voltage. Voltage sags, brownouts, and surges can stress components and
shorten equipment life with worst case catastrophic events destroying valuable equipment. In such real world
conditions, the Torus Power AVR ELITE can protect your equipment and improve the quality of your audio and
video experience.
Series mode surge suppression is built into each AVR ELITE to provide protection against lightning strikes and
other power disturbances, meeting IEEE endurance standards of 6000 volts, 3000 amps, with 1000 repeats.
Summary of AVR ELITE Series Features

Voltage Fault Protection
If the AC voltage supplied to the AVR ELITE is too high or too low voltage (see reference chart at the end
of this section) for 1 second or more, a voltage fault message is displayed and the back panel fault
output is turned on. The unit automatically goes into shut down mode so the voltage to each power
output is automatically turned off even while the mains power to the unit remains in the ON position.
The front panel display will alternate to show either of the following message pairs:
OR
When the AC supply voltage has returned to a normal operating range for 1 minute consecutively the
AVR ELITE will resume normal operation and the High or Low AC Voltage advisory message will no longer
appear on the LCD display. The output zones will provide power again and be turned on in sequential
order with the delay between zones as defined in System Setup.

Notes:
1. The AVR ELITE unit needs to be switched ON at all times for series mode surge protection to be
active. If the AVR ELITE and connected components will not be used for an extended period of
time, it is recommended to disconnect the AVR ELITE unit from main power.
2. There is a 20-second delay built into the AVR ELITE system, to prevent nuisance switching. The AVR
ELITE will take approximately 20-seconds to change relay taps to switch to the properoutput
voltage setting.
3. North American models: Torus AVR ELITE will keep the output constant within the rangeof
120±4V, with an input voltage of 180V to 260V. Between 170V to 180V, and between 260V and
270V, the regulation will be reduced.
4. International models: Torus AVR ELITE will keep the output constant within the range of 240±8V,
with an input voltage of 180V to 260V. Between 170V to 180V, and between 260V and 270V, the
regulation will be reduced.
5. The output current (Amps) displayed on the LCD is the RMS reading of the load. It doesnot
indicate the peak current loads.
6. A drop in the input voltage is normal when increasing the load on the AVR ELITE. This is a result of
the impedance of the power line, a function of the distance from the electrical panel and
transformer regulation.

Component Connection Zones
All Wall Mount AVR-2 ELITE units have of 7 Zones + R IP Addressable zones.
•Zones A to G can be individually controlled and programmed.
•Each zone can be scheduled to turn ON or OFF at any time or day of the week.
•Each zone can also be individually turned ON or OFF through the local web browser interface or Torus Power
Connect account
•Zone R can be programmed as either a controlled outlet or an automatically rebooted Router
outlet.

Toronto, Canada

9 | Page
The Zones on the AVR ELITE switch on in sequence: Zone A first, Zone B second and so on. This will
allow you to select the order in which your components are switched on. For example, components
that should be switched on first (such as front end components) can be connected to Zone A and Zone
B. Components to be switched on last (such as power amplifiers) can be connected to Zones C, D (or
Zones E, F, G in higher capacity units). All output zones will be turned to the ON state when the AVR
ELITE is turned ON. This also applies when output zone(s) were OFF prior to cycling its main power by
turning it OFF and then ON again.
Routers should be connected to Zone R if the automatic reboot feature is to be utilized; if this feature is
NOT to be used, Zone R can be used as an extra controllable output zone. Zone R switches on last. Since
every output on the AVR ELITE is capable of providing full current with no restriction, connecting
components for preferred sequencing will NOT compromise performance.
