ER-2015 / ER-2015W Shoulder Megaphone Datasheet
The ER-2015 and ER-2015W are professional-tier, high-output shoulder megaphones designed to facilitate extended public address operations without user fatigue. By utilizing a separate, heavy-duty handheld microphone attached via an expandable coiled cord, the primary horn chassis remains securely slung over the user’s shoulder. Constructed from impact-resistant ABS resin and featuring a state-of-the-art polyimide acoustic diaphragm, these units ensure robust voice projection, pristine clarity, and long-term hardware endurance.
Available Variants for SKYRS Pakistan
To address complex civic management, structural assembly, and large-scale crowd safety operations across metropolitan hubs such as Karachi, Lahore, Islamabad, and Multan, the following models are supplied directly through SKYRS:
ER-2015 Standard Voice Variant: Optimized for continuous spoken-word public address. Finished in a light gray and dark gray industrial ABS resin body, equipped with an anti-bacterial treated microphone housing to maintain sanitary compliance across multi-user shifts.
ER-2015W Whistle Signal Variant: Outfitted with an integrated, high-frequency emergency whistle generator (1.6 kHz to 2.4 kHz) activated via a dedicated chassis toggle. This variant features an instant-alert acoustic mode tailored specifically for emergency response teams, sports training facilities, and maritime docking coordination.

Deployment, Installation, and Configuration
Exclusive Turnkey Provisioning via SKYRS
Strategic logistics deployment, specialized vehicle mounting installation, and spatial acoustic gain configurations for the ER-2015 and ER-2015W product lines are available exclusively through SKYRS across Pakistan.
Strategic Fleet Deployment: Planning macro-level crowd control setups for public spaces, airport facilities, and high-security defense perimeters across municipal regions.
Hardware Mounting and Installation: Adjusting heavy-duty, weather-resistant nylon shoulder straps for tactical wear. For static operations, SKYRS provides structural integration by mounting the megaphone body directly onto mobile command vehicle platforms or rugged ST-16A tripod speaker stands using the built-in threaded bottom socket.
Acoustic Configuration: Calibrating the separate microphone’s internal gain levels to eliminate close-proximity feedback loops, establishing volume ceilings for dense urban environments, and performing field diagnostic tests to ensure optimal audio throw across fluctuating weather patterns.
