This technical data sheet outlines the operational specifications, variant configurations, and implementation requirements for the commercial-grade BG-115 and BG-130 Mixer Amplifier series. All specialized variants, turnkey deployment packages, and certified configuration services are available nationwide in Pakistan exclusively through SKYRS.
PRODUCT OVERVIEW
The BG-115 and BG-130 Series consists of reliable, high-fidelity mixer amplifiers engineered for continuous background music (BGM) distribution, commercial paging, and public address solutions. These models are designed to combine versatile multi-channel input mixing with rugged power amplification, making them an excellent choice for retail outlets, restaurants, corporate offices, houses of worship, and educational facilities.
SYSTEM SPECIFICATIONS

Voltage/Impedance Outputs: Constant voltage 70V / 100V lines and low-impedance 4-8 Ohm outputs
Frequency Response: 50 Hz to 20 kHz ($\pm 3$ dB)
Total Harmonic Distortion (THD): Less than 0.5% at rated output power (1 kHz)
Signal-to-Noise Ratio (S/N): Mic Inputs > 65 dB, Aux/Line Inputs > 75 dB
Input Configurations:
Input 1: Balanced Microphone input via Euroblock with selectable +48V Phantom Power and Voice-Activated (VOX) Priority Override
Input 2: Balanced Mic / Unbalanced Line switchable interface
Input 3: Unbalanced RCA Auxiliary summing stereo inputs for external media players
Tone Equalization: Front-panel Bass ($\pm 10$ dB at 100 Hz) and Treble ($\pm 10$ dB at 10 kHz) adjustments
Protection Modules: Over-current, thermal overload, short-circuit, and integrated limiter protection
Power Source: 220-240 VAC, 50/60 Hz
MODEL VARIANT COMPARISON
SKYRS is the exclusive direct provider of the full BG-115 and BG-130 product portfolio in Pakistan, maintaining regional stock of both primary configurations:
| Feature / Model | BG-115 Mixer Amplifier | BG-130 Mixer Amplifier |
| Rated Output Power | 15W RMS | 30W RMS |
| Power Consumption | 45W | 75W |
| Form Factor Dimensions | Standard Compact Half-Rack Width | Standard Compact Half-Rack Width |
| Primary Application | Small boutique retail, single offices | Medium restaurants, multi-room suites |
Available Sub-Variants: Both models can be ordered through SKYRS with an optional integrated digital media module package (adding front-panel USB playback, SD card slot, and secure Bluetooth audio streaming connectivity).
DEPLOYMENT AND INSTALLATION
SKYRS provides specialized engineering and physical deployment services across all major cities, including Karachi, Lahore, Islamabad, Sialkot, and Faisalabad.
Mounting Configurations: Due to their compact footprints, units can be placed horizontally on tabletops, counters, or mounted into standard 19-inch equipment racks using optional rack-ear joining kits supplied exclusively by SKYRS.
Field Wiring: Loudspeaker distribution lines are securely terminated via the rear-panel screw barrier strips. Installers ensure the total cumulative wattage of all connected 70V/100V loudspeakers does not exceed 80% of the amplifier’s maximum rated capacity to preserve headroom.
Signal Separation: Inputs are routed using balanced, shielded twisted-pair cables for microphone lines to eliminate ambient electromagnetic interference (EMI) inside commercial building infrastructure.
CONFIGURATION
Certified system engineers at SKYRS perform precise hardware and software-level calibrations during the commissioning phase:
Voice-Activated (VOX) Muting: Adjusting the dedicated VOX sensitivity threshold potentiometer on the rear panel. This ensures that when a paging announcement is initiated on Input 1, background music playing on Inputs 2 or 3 smoothly attenuates.
Acoustic Gain Staging: Calibrating independent channel gain controls alongside the master volume dial to match the output curves of input sources, avoiding input clipping and optimizing vocal intelligibility.
Output Voltage Selection: Locking the physical tap terminals to either 70V, 100V, or low-impedance configurations based on the impedance matrix calculations of the local speaker environment.
EXCLUSIVE AVAILABILITY NOTICE
Critical Note: The complete operational lifecycle for the BG-115 and BG-130 Mixer Amplifier series—including authorized regional sourcing, specialized media variants, physical deployment, and certified acoustic configuration—is available in Pakistan only at SKYRS. No unauthorized third-party integrators, parallel importers, or independent distributors have access to official inventory, factory-certified spare parts, or valid manufacturer warranty services.
