STR Series Integrated Amplifier: The STR Integrated
Amplifier has a well-earned reputation
for being incredibly stable under difficult, low-impedance speaker loads.
Reliability and performance is maintained using carefully selected components,
many of them engineered exclusively in-house at Anthem. Short path design,
superior DAC, and redundant systems (with Advanced Load Monitoring and other
exclusive protective technologies) ensure that peaks are surmounted
effortlessly, and guarantee a long life of high performance.
Massive Toroidal Power Supply: The STR Integrated Amplifier delivers
incredible dynamics thanks to a massive, conservatively rated power supply,
designed with high rail voltages. The advanced-generation toroidal power
transformer minimizes stray magnetic field radiation and ensures ultra-quiet
performance. The resulting power is pure, clean, low-noise; capable of
effortlessly and instantly reproducing the full dynamics of even the most
complex audio recording.
High Current, High Output Amplifier: The massive power supply operates
in harmony with the high-current, high-output amplifier section to continuously
produce an astounding 200 watts per channel into 8 ohms, 400 watts per channel
into 4 ohms, and 550 watts per channel into 2 ohms (20-20kHz w/ <1%THD). Peak production is
effortless and instantaneous with even the most challenging material. The use of
multiple (8) bipolar output devices dramatically reduces distortion while ensuring
extreme linearity, extensive bandwidth, and stress-free reliability.
Advanced Load Monitoring (ALM) Circuitry: Anthem's non-invasive
Advanced Load Monitoring (ALM) circuitry protects the output section of the STR
integrated amplifier by constantly monitoring temperature, current and voltage
to ensure optimum long-term performance. ALM is totally non-invasive; it is not
in the signal path and only engages in the most extreme circumstances to protect
the amplifier from damage by maintaining the safe operating area of the output
Upsampling DAC & Digital Audio Inputs: The Anthem STR integrated
amplifier includes a high-resolution DAC with support for 32-bit/384kHz PCM and
DSD 2.8/5.6 MHz digital audio sources. It will even up-sample lower resolution
digital audio sources to 24-bit/192kHz. The Anthem STR Integrated Amplifier is designed with the shortest possible
signal paths, and differential digital to analog circuitry to cancel artifacts
and keep noise to a minimum. The integrated amp offers USB, AES/EBU, coaxial, &
optical digital audio connectivity.
- Asynchronous USB-B Input: Your Windows PC or Mac computer can
also be connected to STR Integrated Amplifier's asynchronous USB-B input.
Stereo PCM (up to 32-bit/384kHz) and DSD (2.8/5.6MHz) formats are supported
through this connection. Simply connect your computer and use its media
playing software to have music playing through the Anthem STR. If using a Windows PC, a USB DAC driver must first be downloaded
from Anthem's website and installed. Mac OS does not require a separate USB
driver. This high-quality USB audio input transforms digitally stored audio from
your Windows or Mac computer into warm, natural analog sound.
- Digital Audio Inputs: The STR Integrated Amplifier is equipped
with two optical (toslink) digital inputs, two coaxial (RCA) digital inputs,
and one AES/EBU (XLR) digital input. These digital inputs support 2ch PCM
audio (up to 24-bit/192kHz). They are not compatible with Dolby Digital,
DTS, or multichannel PCM.
Analog Audio Inputs: The Anthem STR Integrated Amplifier is outfitted
with balanced, unbalanced, and phono analog inputs. Unwanted changes in volume
when switching to or from an analog source can be prevented by adjusting the
analog input levels from -20 to 20dB in 0.5dB increments. This is especially
useful for some XLR sources that produce higher than typical output level, and
for the phono inputs since cartridge output levels vary considerably between
- Balanced & Unbalanced Analog Inputs: The Anthem STR integrated
amplifier is equipped with a single pair of balanced XLR analog inputs and
four sets of unbalanced stereo RCA inputs. A balanced XLR connection offers
the highest analog transmission quality, particularly over long cable
lengths because it rejects noise and hum pickup.
- Separate MM & MC Phono Inputs: Anthem has also taken into
consideration the resurgent popularity of vinyl long-playing records, and has
included separate inputs for moving magnet (MM) and moving coil (MC) cartridges,
with the phono section completely shielded to maintain signal purity. The MM
input is suitable for turntables using moving-magnet and high-output
moving-coil phono cartridges. The MC input uses input impedance and gain
tailored to low-output moving-coil cartridges. There is also a ground wire
terminal on back of the integrate amp to connect your turntable's ground
wire to prevent excessive hum.
Heavy Duty Binding Posts: Anthem's custom-designed, oversized
binding posts give you the flexibility you need for large-gauge speaker wire (up
to 8AWG), pin-connectors, spade-lugs, and banana plugs (single only). Insulated, non-conductive, color-coded jackets make easy, fast, and
solid connections with no interference or ghosting.
Front & Line-Level Outputs: The Anthem STR Integrated Amplifier
features variable preamp outputs for connection of an external power amplifier.
It also offers fixed line-level outputs suitable for a headphone amp or
Dual Subwoofer Outputs: The STR Integrated Amplifier is
outfitted with two subwoofer outputs & bass mangement giving you more options
for subwoofer configuration. Use one subwoofer or two for both channels, or two
independent right-and-left channel specific subwoofers. The bass management in
conjunction with ARC is uniquely engineered for seamless subwoofer
blending, achieving an incredibly accurate and lifelike performance.
- Crossover Frequency: The subwoofer output crossover frequency can
be set from 25 to 160Hz in 5Hz steps. If you will be using the personal
computer version of ARC, you do not need to select the crossover frequency
since it will be set while running the program.
- Polarity & Phase: Certain subwoofer positions can cause bass
frequency cancellation. When the front speakers and subwoofer are out of
phase or misaligned, they work against each other resulting in weak and
dislocated sounding bass. This can be corrected by adjusting Phase and
Polarity. As a general guide, set Polarity to Normal if the subwoofer is
near the front speakers and to Inverted if the subwoofer is near the back of
the room. Compare Normal to Inverted and use the setting that provides
louder bass. Continue fine-tuning the crossover region using the Phase
control which provides adjustment from 0 to 180 degrees in 5 degree
Anthem Room Correction (ARC): Anthem Room Correction (ARC) is a
proprietary digital signal processing system that allows you to quickly and
accurately optimize the performance of your audio equipment to better suit the
unique parameters of your room. By listening to your room's acoustic signature,
ARC can tune your equipment to correct for the performance-robbing effects
(reflections, resonances, standing waves, etc.) of the various surfaces and
other obstacles in your room. ARC is
easy to use, and just a few simple steps can optimize your speakers for your
unique listening space. ARC is one of the most sophisticated, accurate,
and detailed digital room correction technologies available today. There are 3
ways to calibrate your system using ARC or ARC Mobile.
- Mobile App: Download
Anthem's ARC Mobile app to
your Apple iOS 9.2+ device. This method uses your iOS device's built-in
microphone for measurements. Not compatible with Android.
- Mobile App + ARC Universal Mic: Download
Anthem's ARC Mobile app to
your Apple iOS 9.2+ device, select "ARC Universal Microphone" on the app,
and connect the ARC Universal Microphone to your iOS device for
measurements. Not compatible with Android.
- Windows PC App: Download and install Anthem's ARC software to
your Windows PC. Connect either the calibrated ARC PC Microphone or ARC
Universal Microphone to your Windows PC, and connect the STR integrated
amplifier via USB or LAN. After running your measurements, you can customize
the results, set up multiple configurations, and print correction curve
graph. Not compatible with Mac.
Note: ARC digitally compares a room's acoustic signature to that of the
lab standard. It measures the response of each speaker relative to the listening
area. Then it uses advanced algorithms to eliminate the negative effects of the
obstacles in the room, adjusting response and correcting phase effects. When ARC
removes the obstacles, what's left is the lab standard performance.
Listener Position: Through the Listener Position setting, sound coming
from all speakers is coordinated to reach the listening area at the same time.
This way, proper imaging is achieved. The channel with the greatest distance
setting will have no delay while channels with shorter distance settings will be
delayed accordingly. Distances can be set between 0 to 29' Distances may be set
before or after running ARC (ARC does not set distances).
Listening Modes: The Anthem STR Integrated Amplifier offers four
listening modes to choose from - Stereo, Mono, Both Left, or Both Right.
- Stereo: Left channel audio is output from the left speaker
while right channel audio is output from the right speaker.
- Mono: Blends the left and right channels into both speakers which
can be useful when playing mono records with a stereo cartridge.
- Both Left: Sends the left input to both speakers and can be
useful when playing a mono record with a stereo cartridge when the left
groove wall has less wear and sound better than the right groove wall.
- Both Right: Sends the right input to both speakers and can be
useful when playing a mono record with a stereo cartridge when the right
groove wall has less wear and sound better than the left groove wall.
Volume & Level Adjustments: The Anthem STR allows you to
configure the integrated amplifier's Power-On Volume, Maximum Volume, and Mute
Front-Panel Display: The large Thin Film Transistor (TFT) display on the front-panel
can be seen from across the room, and gives you surprisingly easy operation over
the STR Integrated Amplifier via front-panel and remote control. Each input can
be renamed, up to 10 characters long for easier identification on the
front-panel display. The display's brightness can be set to Max, High, Medium,
Low, or Off.
Remote Control: In addition to front-panel control, the Anthem STR
integrated amplifier comes with an IR wireless remote control. The included IR
remote provides wireless operation of the STR Integrated Amplifier. The
integrated amp also offers IP & system control through its LAN & RS-232 ports,
as well as provides a 12V trigger output and IR input.
