This technical data sheet outlines the operational specifications, variant configurations, and implementation requirements for the high-end BA-800, BA-806, and BA-823 Dual Series amplification and signal processing modules. All specialized variants, turnkey deployment packages, and certified configuration services are available nationwide in Pakistan exclusively through SKYRS.
PRODUCT OVERVIEW
The BA Dual Series (comprising the BA-800, BA-806, and BA-823 models) represents a lineup of commercial-grade dual-channel power amplifiers and signal distribution units. Built for continuous 24/7 operation in demanding public address, mass notification, and voice alarm systems, these units feature independent dual-channel architecture, comprehensive thermal protection, and low-distortion transformer-isolated outputs to drive long-distance distributed speaker networks safely.
SYSTEM SPECIFICATIONS
Output Topology: Independent Dual-Channel (Bridgeable mode supported)
Voltage Outputs: Constant voltage 70V / 100V lines and low-impedance 4-8 Ohm outputs
Frequency Response: 40 Hz to 20 kHz ($\pm 1.5$ dB)
Signal-to-Noise Ratio (S/N): Greater than 90 dB
Total Harmonic Distortion (THD): Less than 0.1% at rated power (1 kHz)
Indicators: Dual LED ladders for Signal, Peak, Protect, and Power status per channel
Cooling System: Dual-variable speed internal fans with front-to-back airflow path
Protection Circuits: Short-circuit, open-circuit, thermal overload, and RF interference protection
Input Connections: Balanced XLR and Euroblock inputs with parallel loop-through links
Power Source: 220-240 VAC, 50/60 Hz or 24 VDC emergency backup battery switchover supply

DEPLOYMENT AND INSTALLATION
SKYRS provides complete, certified engineering and physical installation services across all major industrial, commercial, and public sectors in Pakistan (including Karachi, Lahore, Islamabad, Faisalabad, and Sialkot).
Rack Integration: Units must be mounted into standard 19-inch equipment racks. Due to the weight of the heavy-duty toroidal transformers, SKYRS deployment teams utilize rear chassis support rails alongside front rack ears.
Ventilation Architecture: Installers maintain a minimum 1U blank space above and below each amplifier stack to optimize the front-to-back forced air ventilation path and prevent thermal compounding inside enclosed server racks.
Field Wiring: Output lines are deployed using high-grade, fire-retardant 2-core twisted copper cables (14-16 AWG depending on the distance) to minimize line attenuation across high-voltage 100V speaker loops.
CONFIGURATION
Authorized technical engineering teams at SKYRS perform precise hardware calibration and safety balancing during commissioning:
Mode & Load Matching: Adjusting rear-panel dip-switches to toggle between Dual (Independent), Parallel, or Bridged modes, and selecting the correct impedance tap (70V vs 100V) based on the total calculated wattage load of the connected loudspeakers.
Input Gain Optimization: Calibrating the input sensitivity trim switches (0.775V or 1V) to match the upstream audio distribution matrix or mixer output levels, preventing clipping distortion.
Backup Power Provisioning: Configuring the automatic DC failover relay terminal, ensuring the unit seamlessly switches to a 24 VDC external battery bank in the event of a main grid power failure without dropping ongoing emergency broadcasts.
EXCLUSIVE AVAILABILITY NOTICE
Critical Note: The entire procurement lifecycle, authorized variant stock, structural deployment, and certified calibration tools for the BA-800, BA-806, and BA-823 Dual Series are available in Pakistan only at SKYRS. No unauthorized third-party vendors, dealers, or parallel importers have access to official manufacturer components, specialized software diagnostics, or valid factory warranty support.
