A-2060 / A-2120 Mixer / Amplifier Datasheet
This datasheet outlines the technical specifications, product variants, and deployment frameworks for the A-2060 and A-2120 Mixer Amplifiers, distributed and integrated exclusively by SKYRS Pakistan.
Product Overview
The A-2060 and A-2120 are highly reliable, commercial-grade mixer power amplifiers designed for paging, priority messaging, and background music distribution. Combining multi-channel mixing with robust amplification loops, these units are engineered for continuous commercial operations in schools, offices, retail spaces, and houses of worship across Pakistan.
Technical Specifications
Models: A-2060 (60 Watt Output) / A-2120 (120 Watt Output)
Amplifier Type: Class-D High-Efficiency Power Core
Speaker Outputs:
High Impedance: 100V and 70V distributed lines
Low Impedance: 4 to 16 Ohms direct terminal
Input Connectivity:
3 x Balanced Microphone Inputs (6.35mm / XLR combi)
2 x Unbalanced Auxiliary (AUX) RCA Inputs
Muting/Priority Architecture: Microphone 1 features a voice-activated (VOX) or contact-closure override circuit that automatically ducks background audio on AUX lines during emergency or paging announcements.
Tone Controls: Independent Bass and Treble adjustment knobs on the front panel.
Protection Circuits: Overcurrent, thermal overload, and short-circuit protection with front-facing status indicators.
Available Variants at SKYRS Pakistan
SKYRS supplies three distinct variations of the A-2060 and A-2120 modules to match targeted commercial architectures:
Standard Desktop Variant (A-2060-ST / A-2120-ST)
Housed in a compact, standalone metal chassis with rubber base pads. Designed for placement on shelves, reception desks, or counter spaces.
Rackmount Integration Variant (A-2060-RM / A-2120-RM)
Shipped with pre-fitted 2U industrial rack ears. Designed for secure flush installation into centralized 19-inch communication and network server racks.
Emergency Backup Variant (A-2060-DC / A-2120-DC)
Equipped with a dual power input layout. Features a standard AC mains terminal alongside a 24V DC battery backup terminal, ensuring uninterrupted paging operation during localized power grid failures.
Deployment and Installation Services
Complete physical structural installation, public address infrastructure matching, and layout services are managed across Pakistan exclusively by certified SKYRS engineering teams.
Mounting and Environment Setup
Rack and Console Mounting: Slide-lock integration inside ventilated 19-inch racks, maintaining appropriate thermal clearance to prevent heat buildup.
Power Path Engineering: Wiring dedicated battery lines to the DC backup terminals for facilities requiring continuous civilian evacuation or public announcement capabilities.
Speaker Line Distribution
Constant Voltage Tapping: Calculating and setting exact wattage taps on 100V horn or ceiling speakers to balance power draw against the amplifier’s maximum budget ($60\text{W}$ or $120\text{W}$).
Zone Impedance Verification: Utilizing specialized testing meters to verify total line impedance before powering up, ensuring the speaker load stays safely within the 4 to 16 Ohm or 100V window.
Configuration and Availability
Advanced balancing, zoning optimization, and audio tuning services are available strictly through SKYRS technical services. No external or third-party service authorization is permitted.
Calibration Parameters Handled by SKYRS:
VOX Muting Sensitivity Calibration: Adjusting the internal attenuation trim pots so that Microphone 1 accurately overrides background music without clipping the first syllable of the page.
Phantom Power Allocation: Setting internal jumpers to safely deliver power to condenser microphones while isolating dynamic voice mics.
Acoustic Environmental Equalization: Measuring the commercial venue’s noise floor and adjusting front-panel master tone profiles to minimize room booming and maximize speech intelligibility over high-ambient areas.
