Pro-2123 Dual 12-Inch Line Array System Setup

The Pro-2123 dual 12-inch 3-way line array system from T.I International is engineered for high-output live sound reinforcement, suitable for churches, concerts, rental events, and large indoor or outdoor applications.

Proper setup is essential to ensure optimal performance, coverage consistency, and system safety.

1. System Configuration Overview

A standard Pro-2123 setup typically includes:

Pro-2123 dual 12-inch line array modules

Matching subwoofers (18” or dual 18”)

Power amplifiers

Digital signal processor (DSP)

Rigging frame and flying hardware

Signal cables and power distribution

The system is modular and scalable depending on venue size.

2. Determine Venue Requirements

Before installation, assess:

Audience area width and depth

Ceiling height (for indoor venues)

Expected audience size

Indoor vs outdoor environment

For large venues or outdoor events, multiple cabinets per side are recommended to ensure even SPL distribution and long-throw coverage.

3. Ground Stack or Fly Setup
Option A: Flying (Recommended for Large Venues)

Use the dedicated rigging frame

Secure cabinets using approved flying hardware

Adjust splay angles according to coverage design

Ensure weight load compliance and safety inspection

Flying improves:

Vertical coverage control

Reduced floor reflections

Better long-distance projection

Option B: Ground Stack

Place subwoofers at the bottom

Mount Pro-2123 cabinets above using support poles or stacking hardware

Maintain stable and level alignment

Ground stacking is suitable for medium-sized venues and temporary events.

4. Subwoofer Placement

For best low-frequency performance:

Place subwoofers centrally (clustered) for stronger bass focus
OR

Place subs left and right under each line array stack

Correct sub placement ensures:

Balanced low-frequency response

Reduced phase cancellation

More impactful music performance

5. Amplifier and DSP Configuration

Proper tuning is critical for the Pro-2123 system:

Set crossover frequencies according to factory recommendations

Apply correct delay alignment between subs and tops

Use EQ adjustments based on venue acoustics

Set limiters to protect drivers

T.I recommends using professional DSP processing for optimized system performance.

6. Coverage Optimization

The Pro-2123’s line array design allows controlled vertical dispersion. Adjust cabinet angles to:

Cover front-row listeners

Maintain clarity at the back of the venue

Avoid excessive ceiling reflections

Correct angle calculation significantly improves speech intelligibility and music clarity.

7. Safety and Cable Management

Secure all rigging components

Ensure stable power supply

Separate signal cables from power cables

Conduct full system test before live operation

Safety checks are especially critical for flying systems in public events.
