This document is a service manual for a range of Panasonic speaker systems, specifically the SB-MAF7000PU/GS, SB-MAG7000PU/GS, SB-MAW7000PU/GS, and SB-MAX7000PU/GS models. It provides detailed information for experienced repair technicians on the specifications, disassembly, assembly, wiring connections, and replacement parts for these speaker systems.

Function Description

The manual describes various speaker units designed for audio output. The SB-MAF7000PU/GS and SB-MAG7000PU/GS models are standard speakers, while the SB-MAW7000PU/GS is a subwoofer speaker. The SB-MAX7000PU/GS appears to be a complete speaker system that includes both standard speakers and a subwoofer, as indicated by its packaging diagram showing multiple speaker units. These systems are designed to reproduce sound, with the standard speakers handling a broader frequency range and the subwoofer specializing in low-frequency sounds (bass). The inclusion of "Lighting Wire P.C.B. Assembly" in the disassembly instructions suggests that some models incorporate lighting features, enhancing the aesthetic or functional aspects of the speakers.

Important Technical Specifications

The manual provides specific technical specifications for the different speaker types:

Speakers (SB-MAF7000PU/GS, SB-MAG7000PU/GS):

Speaker unit(s):
- Tweeter: 6 cm cone type
- Woofer: 20 cm cone type
Impedance: 3 Ω
Dimensions (W x H x D): 407 mm x 260 mm x 258 mm
Mass: 5.5 kg

Subwoofer Speaker (SB-MAW7000PU/GS):

Speaker unit(s):
- Super Woofer: 30 cm Cone type
Impedance: 6 Ω
Dimensions (W x H x D): 402 mm x 450 mm x 386 mm
Mass: 13 kg

Notes on Specifications:

Specifications are subject to change without notice.
Mass and dimensions are approximate.
Total harmonic distortion is measured by a digital spectrum analyzer.

The wiring connection diagrams further detail the internal electrical configuration. For the standard speakers (SB-MAF7000PU/GS, SB-MAG7000PU/GS), the tweeter (SP1) is connected in series with a 2.7µF 50V capacitor, indicating a crossover network to filter frequencies, allowing higher frequencies to pass to the tweeter. The woofer (SP2) is connected directly to the speaker terminal. The subwoofer speaker (SB-MAW7000PU/GS) shows a direct connection for its super woofer (SP3) to the speaker terminal, implying that any necessary filtering for the subwoofer is handled externally or by an integrated amplifier not detailed in this specific wiring diagram.

Usage Features

While primarily a service manual, some usage features can be inferred:

Modular Design: The breakdown into "Speakers" and "Subwoofer Speaker" suggests that these units might be used together as a complete sound system (e.g., the SB-MAX7000PU/GS package) or potentially as standalone components, depending on the user's audio setup.
Color Option: The "Product Color: (K)... Black Type" indicates that at least one color option for these speakers is black.
Lighting Elements: The presence of "Lighting Wire P.C.B. Assembly" and "LED Cover" in the exploded views and replacement parts list implies that these speakers incorporate LED lighting, likely for aesthetic purposes or to indicate operational status. This could be a user-facing feature that enhances the visual appeal of the speaker system.
Stacking and Stability: The "STACKING PIN," "PLASTIC BRACKET," and "LEG CUSHION" listed in the accessories bag for the SB-MAX7000PU/GS suggest features for stable placement and potentially stacking multiple speaker units, which is common in modular audio systems.

Maintenance Features

The manual is explicitly designed for maintenance and repair, offering comprehensive guidance for technicians:

Target Audience: "This service information is designed for experienced repair technicians only and is not designed for use by the general public." This emphasizes the complexity and potential hazards involved in servicing these devices.
Safety Warnings: A prominent "WARNING" section highlights the risks of servicing electrical products and stresses that only experienced professional technicians should attempt repairs to prevent serious injury or death. An "IMPORTANT SAFETY NOTICE" further identifies critical components marked with a triangle (▲) in diagrams, emphasizing that these parts must be replaced with manufacturer-specified parts to prevent shock, fire, or other hazards, and prohibits modification of the original design.
Detailed Disassembly and Assembly Instructions: The "Disassembly and Assembly Instructions" section provides step-by-step procedures for accessing and replacing various components, including:
- Front Panel Block
- Tweeter Speaker (SP1)
- Woofer Speaker (SP2)
- Subwoofer Speaker (SP3)
- Lighting Wire P.C.B. Assembly
- Specific instructions are given for removing screws, detaching wires, and carefully separating components to avoid damage. For reassembly, technicians are instructed to reverse the procedures and to clean up bosses and holes and align components properly.
Screw Type Identification: A dedicated section, "Type of screws," lists specific part numbers for different screw types (e.g., XTB4+16AFJK, XTB4+10GFJ, XTB3+10GFJK) and advises using original screws at correct locations, which is crucial for maintaining structural integrity and safety.
Exploded Views and Replacement Parts List: These sections are critical for maintenance:
- Exploded Views: Detailed diagrams show the breakdown of the speaker cabinets and internal components, with numerical callouts corresponding to the parts list. This helps technicians identify the location and arrangement of each part.
- Replacement Parts List: This comprehensive list provides part numbers, descriptions, quantities, and remarks for all replaceable components, including speakers, cabinet parts, PCBs, screws, and accessories. This ensures that technicians can order and use the correct manufacturer-specified parts.
Retention Time Limited (RTL) Parts: The manual introduces the concept of "RTL" parts, indicating that the availability of certain components is limited after production discontinuation. This is an important consideration for long-term maintenance and parts sourcing.
Handling Precautions: Technicians are advised to handle components with care during disassembly/assembly due to potential sharp edges on chassis components.
Cleaning: Instructions for reassembly include "Remove and clean up the bosses and holes," indicating that proper cleaning is part of the maintenance process.

Overall, this service manual provides a robust framework for the professional maintenance and repair of Panasonic's speaker systems, ensuring safety, correct part replacement, and adherence to original design specifications.
