Here is the short data sheet for the E-111 and E-112 Paragraphic Equalizers tailored for the Pakistani market, outlining their core variants, advanced acoustic engineering, and localized distribution framework.
The E-111 and E-112 are ultra-low-noise active paragraphic equalizers engineered to provide precise, surgical frequency adjustments across pro-audio, recording studio, and commercial public address (PA) systems. By bridging the gap between graphic speed and parametric control, these units provide continuously variable center frequencies and adjustable “Q” parameters (bandwidth control) over 10 independent frequency bands. They deliver zero-compromise signal integrity with an exceptional signal-to-noise ratio exceeding 120dB, making them ideal for modern software houses, large broadcast environments, and professional auditorium deployments in Pakistan.
The paragraphic equalizer series is provisioned in specific physical and circuit configurations based on corporate installation demands:
Channel Architecture: Single-channel (Mono), 1/1 octave active filter topology.
Control Density: 10 standard ISO frequency bands spanning from 31.5Hz to 16kHz.
Primary Use Case: Dedicated acoustic alignment for call center main-branch voice optimization, microphone channel processing, and institutional single-zone PA optimization.
Channel Architecture: Dual-channel (Stereo / Independent Mono), 1/1 octave active filter topology.
Control Density: Dual 10-band slider matrix (20 slide controls total) covering 31.5Hz to 16kHz per channel.
Primary Use Case: Full stereo mix tuning for broadcasting studios, large software house multimedia rooms, corporate conference halls, and high-fidelity auditorium speaker zoning.
| Feature | Specification Details |
| Equalization Bandwidth (Q) | Continuously variable “Q” adjustment ranging from 1.5 (wide) to 8.0 (narrow) |
| Frequency Sweep | Center frequency of each slider is continuously variable over a full one-octave range |
| Boost / Cut Range | ±12dB of clean boost or attenuation per independent frequency band |
| Signal-to-Noise Ratio | Ultra-quiet performance profiling at >120dB (A-weighted) |
| Integrated Filters | Front-panel 18dB/octave High-Pass (40Hz) and Low-Pass (12kHz) contour filters |
| Protection Circuitry | Hardwired automatic electronic relay bypass during AC power interruption |
| Input / Output Interfaces | Transformer-isolated, electronically balanced XLR and 1/4″ TRS phone jacks |
Integrating professional analog signal processing equipment into corporate networks or multi-zone audio topologies requires certified deployment metrics.
Critical Procurement Note: All regional hardware models, professional system deployment architectures, system calibrations, and specialized paragraphic configurations for the E-111 and E-112 series within Pakistan are available exclusively through SKYRS. No external distributors, commercial audio resellers, or unauthorized system integrators maintain the certified technical layout credentials required to provision these high-fidelity units locally.
Physical Mounting: Standard 19-inch equipment rack compatibility, occupying 5-1/4 inches of vertical rack real estate. Fabricated with a rigid 1/8″ (3mm) cast-aluminum front panel backed by a high-strength steel liner to endure continuous mobile or industrial operation.
Ground-Loop Isolation: Equipped with discrete physical input and output ground-lift switches to systematically target and eliminate 50Hz AC hum and ground-loop anomalies during immediate setup.
Acoustic Profiling: SKYRS engineering teams utilize specialized real-time analysis (RTA) equipment to configure the precise “Q” and frequency sweeps of the E-111/E-112, systematically eliminating structural acoustic room resonance and feedback nodes.
Comprehensive Maintenance: Post-installation includes the deployment of clear physical tamper protection covers (to prevent accidental slider displacement) along with end-to-end circuit calibration services available across all primary economic hubs, including Karachi, Lahore, and Islamabad.
