Lab Gruppen FA2402 240W Commercial Amplifier with Direct Drive Technology and Energy Star Certification - 000-DA502-00010

Product Overview

The Lab Gruppen FA2402 is a 2-channel, 2x240W commercial power amplifier with Direct Drive Technology, designed for analog distributed audio installations requiring high output power and 70V/100V constant-voltage capability without external transformers. It is the analog counterpart to the FAD2402, suited for installations where Dante network audio is not required and a DSP or analog mixer provides signal routing upstream. The FA2402 is Energy Star certified and appropriate for retail, hospitality, corporate, and institutional commercial audio deployments.

Product Description

The FA2402 delivers 240 watts per channel across two independently switchable output zones, each configurable for low-impedance (4/8 ohm) or high-impedance (70V/100V) constant-voltage speaker loads via rear-panel dipswitch. Lab Gruppen's Direct Drive Technology outputs 70V or 100V distributed audio directly from the amplifier stage, eliminating the need for an external step-up output transformer and reducing equipment cost and rack depth in commercial AV systems. Balanced analog inputs via Euroblock connectors accept signals from DSPs, mixers, and other commercial audio source equipment. A switchable high-pass filter per channel protects small ceiling and pendant speakers from damaging low-frequency content. Fanless convection cooling provides completely silent operation, and Auto Ramp circuitry enables signal-activated power-on with an automatic 20-minute sleep timer for energy-efficient operation in spaces with variable occupancy. The unit ships in a 1U half-rack enclosure with joining brackets for rack, wall, or table mounting, making it adaptable to a variety of equipment cabinet and rack configurations.

Frequently Asked Questions

Q: What is the difference between the FA2402 and the FAD2402?

A: Both are 2x240W Direct Drive amplifiers. The FAD2402 adds a Dante network audio interface for IP audio distribution over Ethernet. The FA2402 uses only analog Euroblock inputs and is suited for installations where a separate DSP or mixer handles audio routing without a Dante network.

Q: Does the FA2402 require an output transformer for 70V speaker systems?

A: No. Direct Drive Technology allows the FA2402 to output 70V or 100V directly from the amplifier stage. Standard 70V speaker tap transformers at each speaker are still required, but no amplifier-side transformer is needed.

Q: What type of input connector does the FA2402 use?

A: The FA2402 uses 3-pin Euroblock (also called Phoenix-style) balanced analog input connectors, which are standard for commercial AV installations and compatible with most commercial DSPs and mixers.

Q: Can the two output channels be configured for different speaker impedances?

A: Yes. Each output channel is independently switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) operation via rear-panel dipswitches.

Q: How much power can each 70V output channel support?

A: Each channel provides 240W at 70V. The combined tap wattage of all speakers on that channel must not exceed 240W for reliable, undistorted operation.

Q: Is the FA2402 fan-cooled or passively cooled?

A: The FA2402 uses fanless convection cooling with no moving parts, providing completely silent operation suitable for occupied commercial spaces including offices, hotel lobbies, and conference rooms.
