Inter-M L-1400 เครื่องขยายเสียง 2-Channel 280W (8Ω)/450W (4Ω)/700W (2 Ω) Professional Amplifier

The new L-Series Power Amplifiers deliver high-efficiency and powerful sonic performance for audio professionals.

Our engineers used Class-H technology to create amplifiers with high efficiency and improved reliability. Extensive 

protection circuitry guards against over-voltage and excessive current, temperature-related problems, shorted outputs, 

and DC voltages. 

Additionally, clip-limiting circuitry, variable-speed cooling fans, and a damping factor greater than 400, combine together 

to make impressive high-power professional amplifiers. All models feature popular connectors for inputs and outputs: balanced

inputs (combination 1/4” TRS and XLR); and locking speaker connectors and 5-way binding posts on the outputs. 

This combination of advanced design and extensive protection circuitry offers you reliability, stability, and exceptional performance 

for the most exacting sound reinforcement applications.

Feature

- 2Ω - load stable per channel, 4Ω - load stable in bridge mono

- 2U rack space

- Selectable High Pass Filter on each channel

- Clip limiter circuitry

- Forced air cooled (front panel intake, rear panel exhaust)

- Front panel indicators for different operating modes

- Front panel indicators for output signal level, clip, protect, and power

- Rack Ears for permanent installation in a standard 19” (rack mount width) enclosure.

- Detachable AC power cord
