A-706 Integrated Mixer/Amplifier Datasheet
This datasheet outlines the technical specifications, product variants, and deployment frameworks for the A-706 Integrated Mixer/Amplifier (60W),TOA distributed and engineered grains exclusively by SKYRS Pakistan.
Product Overview
The A-706 is a high-performance, professional-grade 60W integrated mixer power amplifier engineered for premium public address, zoning paging, and multi-source background music distribution. Designed for continuous commercial operation, it offers advanced multi-channel mixing, excellent acoustic clarity, and flexible output options for corporate offices, retail environments, educational spaces, and houses of worship across Pakistan.
Technical Specifications
Model: A-706
Rated Power Output: 60 Watts RMS
Amplifier Topology: High-Efficiency Class-D Core
Speaker Output Interface:
Constant Voltage Lines: 100V and 70V distributed terminal blocks
Low Impedance: 4 to 16 Ohms direct terminal connection
Input Channels:
4 x Balanced Microphone/Line Inputs (XLR / 6.35mm Combi jacks)
2 x Auxiliary (AUX) Stereo RCA Inputs
Priority and Muting: Microphone 1 features a Voice-Activated (VOX) or dry contact-closure override circuit that automatically mutes or ducks background audio during active announcements.
Frequency Response: 50 Hz to 20 kHz (optimized for crisp vocal projection and balanced music rendering)
Tone Controls: Independent front-panel Bass and Treble adjustment knobs.
Protection Architecture: Built-in safety arrays against short circuits, open circuits, thermal overload, and output overcurrent with front-facing LED status indicators.
Available Variants at SKYRS Pakistan
SKYRS builds, configures, and supplies three tailored hardware variations of the A-706 platform to match targeted infrastructure demands:
A-706-Standard Desktop (A-706-ST)
Housed in a compact, standalone matte-black metal enclosure with anti-vibration rubber feet. Designed for direct placement on reception counters, desks, or open AV shelving unit configurations.
A-706-Rackmount Integrated (A-706-RM)
Shipped with pre-fitted 2U industrial rack ears for seamless, secure flush installation inside central 19-inch communication, networking, or broadcast server racks.
A-706-Emergency DC Backup (A-706-DC)
Equipped with an auxiliary 24V DC power input terminal alongside the standard AC mains terminal. This configuration guarantees uninterrupted public address operations during localized electrical grid failures by instantly drawing from backup battery banks.
Deployment and Installation Services
Complete physical deployment, public address system architecture planning, and line infrastructure matching are managed across Pakistan exclusively by certified SKYRS field technician teams.
Mounting and Environment Setup
Enclosure and Rack Integration: Slide-lock 2U installation inside ventilated enclosures, maintaining strict thermal budget clearances to prevent heat accumulation.
Shielded Cable Management: Strategic routing of low-smoke zero-halogen (LSZH) shielded mic lines away from high-voltage electrical mains to prevent 50Hz hum and electromagnetic cross-talk.
Distributed Line Management
Constant Voltage Tapping: Precision calculation and tapping of 100V/70V speaker arrays to balance individual space wattages against the amplifier’s maximum $60\text{W}$ budget.
Loop Impedance Verification: Utilizing specialized audio load meters to verify total line impedance before powering up, protecting the internal output transformer from premature component wear.
Configuration and Availability
Advanced system balancing, signal path optimization, and priority zoning configurations are available strictly through SKYRS technical teams. No third-party field maintenance, calibration, or debugging is authorized.
Calibration Parameters Handled by SKYRS:
VOX Overriding Sensitivity Thresholds: Adjusting internal attenuation trim pots so that primary paging microphones accurately override background music without cutting off the speaker’s first words.
Phantom Power Allocation: Setting internal motherboard jumpers to safely deliver power to specialized condenser paging microphones while isolating dynamic voice mics.
Acoustic Environmental Tuning: Measuring the venue’s localized noise floor and modifying master tone profiles to minimize architectural booming and maximize speech intelligibility over high-ambient noise areas.
