This document describes the Panasonic SA-HE40 AV Control Receiver, an amplifier and tuner designed for home theater use.

Function Description:

The SA-HE40 is a versatile AV Control Receiver capable of decoding various digital audio signals and providing surround sound effects. It functions as an amplifier, FM/AM tuner, and a central control unit for a home theater system.

Amplifier: The unit features a multi-channel amplifier with RMS output power of 150 W per channel (6 Ω) for the front channels and 80 W per channel (4 Ω) for surround and center channels in Dolby Digital mode. In stereo mode, it delivers 150 W per channel (6 Ω) for the front channels. The total RMS output power is 540 W. It supports tone controls for Bass and Treble, adjustable from +10 dB to -10 dB at 50 Hz and 20 kHz respectively.
Tuner: It includes an FM/AM tuner. The FM frequency range is 87.50 MHz to 108.00 MHz, with a usable sensitivity of 2.2 µV/75 Ω (IHF'58). The AM frequency range is 522 kHz to 1611 kHz (9 kHz steps) or 530 kHz to 1620 kHz (10 kHz steps). It supports RDS (Radio Data System) broadcasts, displaying information like program service (PS), program type (PTY), and frequency.
Digital Input Decoding: The receiver can decode Dolby Digital, DTS, and PCM signals, including PCM with sampling frequencies of 96 or 88.2 kHz. It cannot decode other digital signals like MPEG or Dolby Digital RF signals from a laser disc player.
Surround Sound Processing: It incorporates Dolby Pro LogicII for adding surround effects to stereo sources, offering MOVIE, MUSIC, and PANORAMA modes. It also features Sound Field Control (SFC) modes for enhanced sound experiences with PCM or analogue stereo sources, including LIVE, POP/ROCK, VOCAL, JAZZ, DANCE, PARTY, DRAMA, ACTION, SPORTS, MUSICAL, GAME, and MONO.
Recording Functionality: The unit allows recording from any analog source (except DVR/DVD-P IN) to a connected DVR/DVD-P OUT device. Digital sources cannot be recorded directly.

Usage Features:

Speaker Setup: Detailed instructions are provided for optimal speaker placement (front, center, surround, subwoofer) and connection to the receiver. Speaker size (LARGE, SMALL, NONE) and distance from the seating position (1.0 to 10.0 m) can be configured. A bass cut-off filter (80 Hz, 100 Hz, 120 Hz, 150 Hz, 200 Hz) for front speakers is adjustable.
Digital Input Settings: Input settings for digital terminals (TV, DVR/DVD-P) can be changed between optical and coaxial to match connected equipment.
Speaker Output Level Adjustment: Individual speaker output levels (center, surround right, surround left, subwoofer) can be adjusted from -10 dB to +10 dB relative to the front speakers. The subwoofer level has specific settings: MIN, 5, 10, 15, MAX, or OFF. A test signal helps balance levels.
Tone and Balance Control: Bass and treble levels, as well as the balance of front speakers, are adjustable via the menus.
Surround Effect Customization:
- Dimension Control (DIMEN): Adjusts the effect of Dolby Pro LogicII MUSIC and PANORAMA modes, shifting sound between front and surround speakers (-3 to +3).
- Center Width Control (C-WDTH): Adjusts the effect of Dolby Pro LogicII MUSIC and PANORAMA modes to create a more natural sound image, from center-dominant (0) to spread-out (7).
- Center Focus: Enhances dialogue clarity from the center channel, making it seem to originate from the television.
- SFC Effects Adjustment: Speaker levels and delay times for surround speakers can be adjusted for each SFC mode.
Sleep Timer: Allows setting a timer (30, 60, 90, 120 minutes) to automatically turn off the unit.
Dimmer: Adjusts the display brightness (levels 1, 2, 3, or OFF) for better viewing in dark rooms.
Muting: Temporarily mutes the audio output.
Radio Tuning: Supports direct tuning by frequency, automatic presetting of stations, manual presetting, and channel selection. AM frequency step (9 kHz or 10 kHz) is selectable. Features for reducing excessive noise during FM stereo (monaural mode) and AM reception (BEAT PROOF mode) are available.
Remote Control: The supplied remote control (N2QAYB000010) operates the receiver and can also control Panasonic DVD recorders, DVD players, and televisions by setting specific codes. It requires two AA batteries.
Safety Precautions: Emphasizes proper placement on a flat, stable surface, avoiding direct sunlight, high temperatures, humidity, and excessive vibration. Warns against blocking ventilation, placing heavy objects or open flames on the unit, and using incorrect power sources. Advises against self-repair and handling the power plug with wet hands.

Maintenance Features:

Cleaning: The unit should be wiped with a soft, dry cloth.
Chemicals: Avoid using alcohol, paint thinner, or benzine for cleaning. If using chemically treated cloths, follow their instructions.
Power Saving: The unit consumes 1 W in standby mode. For long periods of disuse, unplugging it from the AC mains socket is recommended to save power, though some memory items may need to be reset afterward.
Cooling Fan: The cooling fan operates only at high power output levels. Ensure the fan is not obstructed.
