Overview

The NAD T 760 is a Surround Sound Receiver designed for home theater systems, offering a comprehensive set of features for audio and video processing, amplification, and radio reception. It is equipped to handle various audio and video sources, including digital and analog inputs, and provides multi-channel amplification for a surround sound experience.

Function Description:

The T 760 serves as the central hub for a home entertainment system, integrating a tuner, pre-amplifier, and multi-channel power amplifier into a single unit. It supports Dolby Digital and DTS surround sound modes, as well as Dolby Pro Logic and NAD's proprietary EARS (Enhanced Ambiance Retrieval System) Surround Mode. The receiver allows users to select active audio and video inputs, control volume, adjust tone, and configure speaker settings for optimal sound performance.

For video, the T 760 handles both composite video and S-Video signals, routing them to a monitor output for display on a television or video projector. It features multiple video inputs (Video 1-5) to accommodate various video devices like DVD players, VCRs, satellite/cable receivers, camcorders, and video game consoles.

The audio section includes inputs for CD players, tape recorders, and external 5.1 channel decoders. It also incorporates an AM/FM tuner with RDS (Radio Data System) capabilities, allowing for the display of station names and radio text where available. The built-in power amplifiers drive up to five speakers (Front Left, Front Right, Center, Surround Left, Surround Right), and a dedicated subwoofer pre-out is provided for connecting an active subwoofer.

The NAD-Link feature enables centralized control of other NAD components (like CD players or cassette decks) equipped with NAD-Link connectors, allowing the receiver's remote control to manage a complete system.

Important Technical Specifications:

  • Amplification: Five built-in power amplifiers for Front Left, Front Right, Center, Surround Left, and Surround Right speakers.
  • Speaker Impedance: Minimum 4 ohms per speaker for Front, Center, and Surround channels.
  • Subwoofer Output: Dedicated pre-out for active subwoofers.
  • Digital Audio Inputs: Three digital audio inputs (one optical, two coaxial) for DVD, CD, or other digital sources. Optical Digital Input 1 is linked to Video 1 input. Coaxial Digital Input 2 is linked to Video 2 input. Coaxial Digital Input 3 is linked to Video 3 input.
  • Analog Audio Inputs: Multiple RCA inputs for CD, Tape 1, and various video sources (Video 1-5).
  • Video Inputs: Multiple composite video and S-Video inputs (Video 1-5). Video 4 only supports composite video.
  • Monitor Outputs: Composite video and S-Video outputs for connecting a TV or video monitor.
  • Tuner: AM/FM tuner with RDS (PS, RT) support.
  • AM Tuning Steps: Switchable between 10kHz (120V version) and 9kHz (230V version).
  • FM Tuning Steps: 0.1 MHz (120V version) or 0.05 MHz (230V version).
  • Volume Control: Ranges from ∞ to +18dB.
  • Tone Controls: Bass and Treble controls with a 'flat' detent at 12 o'clock position.
  • Soft Clipping: NAD's proprietary circuit to minimize audible distortion when the amplifier is overdriven.
  • NAD-Link: For system integration and control with other NAD components.
  • Switched AC Outlets (120V North American versions only): Total 120W, 1A max.
  • Cooling: Internal cooling fan that operates when internal components reach a certain temperature.
  • Display: Vacuum Fluorescent Display (VFL) for showing operational information.
  • On-Screen Display (OSD): Elaborate OSD facility for setting up surround sound parameters, accessible via a connected TV or monitor. Supports PAL and NTSC video systems.

Usage Features:

  • Input Selection: Front panel buttons and remote control allow selection of active audio and video inputs (Video 1-5, Tape Monitor, CD, FM, AM, EXT. 5.1).
  • Surround Mode Selection: Dedicated buttons on the front panel and remote control to cycle through available surround sound modes (Dolby Digital, DTS, Pro Logic, EARS, Stereo). The receiver automatically detects Dolby Digital or DTS signals when a digital audio input is used.
  • Speaker Configuration: Comprehensive speaker settings via OSD, allowing users to define speaker size (Large/Small) and activity (On/Off) for Front, Center, and Surround channels, and Subwoofer (On/Off). Three factory presets are provided for typical installations.
  • Channel Balance: Individual trim adjustments for Center, Surround Left, Surround Right, and Subwoofer channels (±10dB range) to achieve equal loudness at the listening position. A test signal generator is available for calibration.
  • Channel Delays: Adjustable delay times for Center (0-5ms) and Rear (0-15ms for Dolby Digital, 15-30ms for Dolby Pro Logic) speakers to ensure synchronized sound arrival at the listening position. Not available in DTS mode.
  • Dynamic Range Control: For Dolby Digital sources, allows incremental reduction of dynamic range (100%, 75%, 50%, 25%) for comfortable listening at various volume levels.
  • Tuner Presets: Stores up to 40 radio stations (30 FM, 10 AM) for quick recall.
  • FM Mute/Mono: Toggles between stereo and mono reception and engages/disengages muting to reduce noise from weak signals.
  • Sleep Timer: Remote control feature to automatically switch off the unit after a preset time (90, 60, 30 minutes, or off).
  • Headphone Output: 1/4" stereo jack for private listening, with volume and tone controls active. Automatically mutes speakers and Audio Pre-Outs when headphones are inserted.
  • Soft Clipping: User-selectable feature to gently limit output and minimize distortion when the amplifier is overdriven.
  • Remote Control: Full-function remote handset with access to all key functions, OSD navigation, and control of other NAD components via NAD-Link.

Maintenance Features:

  • Cleaning: Use a dry soft cloth; lightly dampen with soapy water if necessary. Avoid benzine, thinner, or other volatile agents.
  • Power Management: Disconnect from AC socket if unused for a long period.
  • Ventilation: Ensure adequate ventilation by not blocking air-flow openings; avoid placing on soft surfaces or in enclosed spaces.
  • Troubleshooting Guide: The manual provides a troubleshooting section for common issues like no sound, channel imbalance, remote control malfunction, and tuner reception problems, along with suggested causes and solutions.
  • Servicing: Refer servicing to qualified service personnel. Do not attempt to open the unit or remove the cover, as there are no user-serviceable parts inside. Use only factory-authorized replacement parts for repairs.
  • Battery Replacement: Replace AAA (R03) batteries in the remote control, ensuring correct polarity.
  • Antenna Placement: Experiment with AM loop antenna and FM ribbon antenna placement for best signal strength and lowest background noise. External antennas are recommended for poor reception areas.
