Adcom GTP-870HD User manual

Proudly presenting ADCOM’s latest melding of digital precision with analog horsepower:
The GTP-870HD 7.1 Multichannel Tuner/Preamplifier
GTP-870HD
Multichannel Tuner/PreAmp
Digital precision, analog horsepower
Back to Basics-
The separate Great Tuner-Preamp.
In recent years the video-centric custom in-
stallation crowd has shifted en masse to the
specification of low-cost integrated A/V Re-
ceivers for install convenience and rack space
conservation - not for purposes of maximizing
audio and video performance.
When opportunity arises for a home theater and music playback system to upgrade from mere convenience-based “good” to actual performance-driven
“better or best” categories, A/V separates still rule. Why is that? Greater “real estate” to maximize uncompromised circuit design and component
choices. Banishment of noise-inducing elements far apart from sensitive, low-level signal information. Flexibility and upgradeability. Raw horsepower...
to name but a few.
The entirely separate new GTP-870HD preamp/processor offers superlative technical specifications along with a comprehensive list of useful features
and digital signal-processing modes. Foregoing jewelry-mart cosmetics and bazillions of buttons in exchange for premium-grade circuit components,
the GTP-870HD delivers long-lasting build quality, swappable internal circuit-card construction and robust all-discrete serial port communication for
remote control, updates and upgrades.

GTP-870HD
For consumers embracing HDTV and who have HDMI inputs on their display
the GTP-870HD includes a 1080p-capable, true-HD video scaling engine
based on National Semiconductor’s AVC2510 dual-channel video format
converter, more commonly found in products of considerably higher cost.
The HD scaler allows cable, game, DVD, satellite receiver and broad-
cast television video input to be scaled to VGA, 480i, 576i, 480p, 576p,
720p50, 720p60, 1080i, 1080p50 and 1080p60 to match the display’s
native resolution-at a remarkably affordable price.
Video signal decoding and format upconversion tasks are performed by
the high resolution TI TVP-5146, comprised of four 10-bit A-D converters
with robust sync detection for weak, noisy or off-standard input signals and
international signal system compatibility.
Video digital to analog conversion is mastered by Analog Device’s ADV-
7173, with six integral 10-bit converters that in the GTP-870HD implemen-
tation produce a beyond-broadcast quality Component Video bandwidth of
over 200 MHZ!
GTP-870HD Tuner/Preamplifier
Specifications
Audio signal processing tasks are conducted by the Cirrus Logic 493-series
DSP, a dual 24-bit 192kHz compatible engine for high fidelity decoding of
current DOLBY Digital, DOLBY Pro-Logic, DTS and other selective, useful
listening modes. Both audio D/A and A/D converters are likewise 24-bit,
192kHz solutions from Cirrus Logic, engineered for wide dynamic range,
negligible distortion and low noise, resulting in excellent sound quality. Ex-
ternal 7.1 analog inputs with full DSP bypass capacity allows the GTP-870-
HD to be used as a premium-performance analog preamplifier, with choice
of audio output on either single ended RCA or Differential-balanced XLR.
No proprietary cones of silence, no physics-beating secret circuits form
the marketing department. Just superior engineering of separates perfor-
mance and lasting value for your money. What you’ve come to expect from
ADCOM.
