Stage Amplifiers

Features and Benefits

Value Engineered

Stage amplifier provides true JBL performance at an affordable price while now lacking the features needed to properly tune and optimize performance. 

Compact footprint

With it becoming more and more difficult to find spacious locations for amplifier mounting, Stage has been developed in a small compact form factor 
to allow more location versatility. 

Full On-Board Protection

Stage amplifier has on-board circuitry to protect them from shorts, temperature, overvoltage and undervoltage. An LED indicator is included on all 
four models to let you know when one of these conditions exists. 

Reliability 

JBL is one of the greatest audio brands in the world. This is not a coincidence given the arduous testing and quality control. We take our craft seriously 
and want every consumer to have a world-class experience that lasts and lasts. 

Input Level Control

When Low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 5.0Vrms. When High-level inputs are used,  
this control adjusts the input sensitivity between 0.5Vrms and 15Vrms.

Switchable bass EQ

This provides an available bass boost at 45Hz of 6dB or 12dB, serving as a great tool to optimize subwoofer and loudspeaker performance based 
on location and enclosure type.

Cool industrial design

Black with deep grooves, silver silkscreen, anodized JBL badge top-center with orange end panels and bottom.

Crossover mode switch*

LPF crossover controls is switchable between 0dB to 12dB at 45Hz giving user ability to adjust sound to the environment and/or application.
