Integra Announces 'Dot 2' Network AV Receivers

Integra has announced the next iterations of its reference-grade network A/V receivers with the company's new “Dot 2” series. The new offerings step up from 7.2 to 9.2-channels and are the first available Integra units to receive the “Works With Sonos” certification. The three new products are as follows: DRX-5.2 9.2-Channel Network A/V Receiver (MSRP: $1,700 USD / $2,200 CAD), DRX-4.2 9.2-Channel Network A/V Receiver (MSRP: $1,400 USD / $1,800 CAD) and the DRX-3.2 9.2-Channel Network A/V Receiver (MSRP: $1,000 USD / $1,400 CAD).

Both the DRX-5.2 and the DRX-4.2 include THX Certified Select approval for theater reference sound, and support Enhanced HDBaseT LAN connection to achieve HDCP 2.2-compliant 4K/60Hz video transmission. Power Over Cable (POC) is combined with an optional HDB-RX1 HDBaseT Receiver, and IR and RS-232C control. The now THX Certified DRX-3.2 has received a 'massive across-the-board upgrade' including Zone 2 HDMI with matrix switching, Zone 2 OSD and Powered Zone 3 capabilities for audio. The three units will support Dolby Atmos and DTS:X formats up to 5.2.4 or 7.2.2 channels, with both the DRX-4.2 and DRX-5.2 able to support 7.2.4-channel configuration with an external amp.

All three units include HICC (High Instant Current Capability), an all steel/aluminum chassis for an enhanced anti-resonant environment to surround the internal circuitry, and 'hand-selected parts with nearly zero tolerances,' claims Integra. There is also gold-plated connectivity for optimal signal to noise ratios.

Integra’s new Dot 2 series carries the “Works with Sonos” certification. Once the Integra receiver is connected to Sonos Connect, it will enable owners to send any music or source on their Sonos app to the receiver. The receiver can be grouped to other Sonos devices on a network or it can be used independently. Firmware enabling this function will be available early in June.

Onboard all three units is AccuEQ Advance, a new multi-point room-acoustic calibration system that eliminates standing waves (dead areas where sound-wave peaks don’t move spatially, and compromise reproduction quality when sounds of the same frequency interact). Users can place the setup mic in three positions to assure optimal imaging across a wide soundstage following an automated calibration process. AccuEQ Advance is enhanced by AccuReflex technology, which aligns the phase of directional and non-directional sounds for cohesive object-based audio reproduction through Dolby Atmos-enabled speaker systems.

Integra’s audio performance is driven by a low-impedance amplification system with a 'discrete output stage circuitry and custom-made capacitors.' The DRX-5.2 is rated at a claimed 120 Watts per channel (8 Ohms, 20 Hz–20 kHz, 0.08 % THD, 2 Channels Driven, FTC), while the DRX-4.2 boasts 100 W/channel (8 Ohms, 20 Hz–20 kHz, 0.08 % THD, 2 Channels Driven, FTC). The base model DRX-3.2 packs is rated at 90 W/channel (8 Ohms, 20 Hz–20 kHz, 0.08 % THD, 2 Channels Driven, FTC).

Connected to a wireless access point, the Integra Dot 2 series also includes the following wireless audio capabilities:

• Chromecast built-in wireless audio streaming to work with the Google Assistant

• Music streaming from DTS Play-Fi-enabled applications

• FlareConnect™ multi-room network and analog wireless audio distribution to compatible components and speakers

• On demand services such as Amazon Music, Spotify, TIDAL, TuneIn, Pandora and Deezer

• AirPlay Audio Streaming from iTunes and iPad, iPhone, and iPod touch

Each unit supports the following custom install features:

• Bi-directional ethernet with IP Control for home automation

• RS232 port for control

• HDBaseT output capability on selected models

• Zone 2 Pre-/Line Out for distributed audio playback in another room

• Zone 2 DAC for S/PDIF, NET and analog sources

• Independent Zone 2 bass/treble/balance control

• IR inputs and 1 output

• Three 12V trigger outs with adjustable delay
