Lab Gruppen CA2401 240W Commercial Amplifier with Energy Star Certification

Product Overview

The Lab Gruppen CA2401 is a single-channel, 240W commercial power amplifier with Energy Star certification, designed for high-power single-zone amplification in commercial distributed audio systems. It delivers 240W into a single 70V/100V or low-impedance output zone, making it the highest-power single-channel option in the CA series and appropriate for large commercial spaces including retail showrooms, restaurant dining areas, hotel ballrooms, and auditoriums where maximum mono output power is needed from a compact, Energy Star certified amplifier. Signal processing and source selection are handled by upstream commercial DSP or zone controller equipment.

Product Description

The CA2401 provides 240 watts into a single output channel, switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation via rear-panel dipswitch. A balanced analog Euroblock input accepts line-level signals from commercial DSPs, zone controllers, matrix mixers, and mixer amplifiers. Rear-panel dipswitches configure output voltage and input gain without software or front-panel menu navigation, keeping installation straightforward for commercial AV integrators. A switchable 80Hz high-pass filter protects commercial ceiling and pendant speakers from low-frequency content. Auto Ramp circuitry activates the CA2401 automatically when input signal is detected and transitions to sleep mode after 20 minutes of inactivity, supporting Energy Star compliance and reducing operating costs in spaces with variable occupancy. Fanless convection cooling provides completely silent operation in noise-sensitive commercial environments. The unit ships with joining brackets for 1U half-rack, wall, or table mounting. The CA2401's 240W output makes it suitable for larger 70V speaker runs where lower-power single-channel amplifiers would be insufficient.

Frequently Asked Questions

Q: What is the difference between the CA2401 and the CA2402?

A: The CA2402 is a 2-channel unit delivering 240W per channel across two independent zones. The CA2401 combines all 240W into a single output channel for maximum single-zone power. Use the CA2401 when one high-power zone is needed, and the CA2402 when two zones are required.

Q: How many 70V speakers can the CA2401 support?

A: The total wattage of all speaker tap settings on the 70V output must not exceed 240W. With 8W speaker taps, up to 30 speakers could be supported within the power budget.

Q: Does the CA2401 include any mixing capability?

A: No. The CA2401 is a power amplifier only with a single balanced input. For multiple sources, pair it with a Lab Gruppen CM41 or CM82 mixer, or choose a CPA or CMA series mixer amplifier instead.

Q: Can the CA2401 power both 4-ohm and 70V loads?

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

Q: Is the CA2401 suitable for installation in a standard equipment rack?

A: Yes. The CA2401 is a 1U half-rack unit with included brackets for rack, wall, or table mounting. Two CA2401 units can be joined side-by-side to occupy a full 1U rack space.

Q: What happens when the CA2401 is left on without any audio signal?

A: Auto Ramp monitors the input signal level. After 20 minutes of inactivity, the CA2401 transitions to a low-power sleep mode and resumes full operation automatically when signal returns.
