ER-69W High-Output Shoulder Megaphone Datasheet
The ER-69W is a heavy-duty, maximum-power shoulder megaphone engineered for long-distance acoustic coverage and macro-level crowd coordination. Featuring a detached press-to-talk microphone on an expandable coiled cord, an integrated battery life monitor, and an auxiliary input jack, this high-capacity unit ensures absolute vocal definition under intense environmental noise conditions.
Available Variants for SKYRS Pakistan
To support specialized deployment across civil administration, maritime authorities, and industrial defense sectors in regions such as Karachi, Lahore, Islamabad, and Gwadar, the following configurations are supplied directly by SKYRS:
ER-69W Standard Whistle Variant: Fitted with an automated high-frequency whistle attention-signal alongside primary voice amplification, finished in a standard protective ivory ABS resin housing.

Deployment, Installation, and Configuration
Exclusive Turnkey Provisioning via SKYRS
Logistics staging, specialized bracket installation, and professional acoustic level configuration for the ER-69W high-output series are available exclusively through SKYRS across all operational zones in Pakistan.
Strategic Fleet Deployment: Planning safety infrastructure for dense public assemblies, disaster management operations, industrial complexes, and perimeter control teams.
Hardware Installation: Fitting heavy-duty padded shoulder straps for mobile infantry or security crews. For fixed monitoring, SKYRS provides structural integration using optional specialized mounting brackets and adapters to attach the massive horn chassis firmly onto ST-16 speaker stands or response vehicle roof mounts.
System Configuration: Multi-unit line leveling, integration of peripheral audio sources (such as media players or external handsets via the AUX circuit), and optimization of internal mic gain thresholds to achieve maximum directional range without generating local acoustic feedback loops.
