Lab Gruppen CA1202 2 x 120W Commercial Amplifier with Energy Star Certification

Product Overview

The Lab Gruppen CA1202 is a 2-channel, 2x120W commercial power amplifier with Energy Star certification, designed for permanent installation as a dual-zone amplification endpoint in commercial distributed audio systems. It accepts balanced analog signals from an upstream DSP, zone controller, or mixer and delivers 70V/100V or low-impedance audio across two independent speaker zones, providing reliable two-zone amplification without an integrated mixer for commercial installations where signal processing is handled separately. The CA1202 is fanless, convection-cooled, and configurable via rear-panel dipswitches.

Product Description

The CA1202 provides 120 watts per channel across two independently switchable output channels, each configurable for low-impedance (4/8 ohm) or high-impedance (70V/100V) constant-voltage speaker loads via rear-panel dipswitch. Balanced analog Euroblock inputs accept line-level signals from commercial DSPs, zone controllers, matrix mixers, and other professional audio source equipment. Rear-panel dipswitches allow installers to set output voltage and input gain per channel without software. An 80Hz switchable high-pass filter per channel protects commercial ceiling and pendant speakers from low-frequency overload. Auto Ramp circuitry activates the CA1202 on signal detection and enters sleep mode after 20 minutes of inactivity, maintaining Energy Star compliance and reducing operating costs. Fanless convection cooling provides completely silent operation appropriate for offices, hotel spaces, and conference rooms. The unit ships with joining brackets for rack, wall, or table mounting as a 1U half-rack unit. The CA1202 is an appropriate two-zone amplification endpoint in DSP-based commercial AV systems where mixing, EQ, and zone routing are handled upstream.

Frequently Asked Questions

Q: Does the CA1202 include a built-in mixer?

A: No. The CA1202 is a power amplifier with one balanced input per channel. For multi-source mixing, pair it with a Lab Gruppen CM82 or CM41 mixer, or use a CMA or CPA series mixer amplifier instead.

Q: What is the difference between the CA1202 and the CA2402?

A: Both are 2-channel Energy Star commercial power amplifiers. The CA2402 provides 240W per channel versus 120W per channel for the CA1202. Choose the CA1202 for smaller rooms and shorter 70V runs, and the CA2402 for larger spaces with higher total speaker tap wattage.

Q: Can both output channels be configured for 70V simultaneously?

A: Yes. Each output channel is independently switchable between low-impedance and high-impedance operation, so both channels can operate at 70V simultaneously for dual-zone 70V distributed speaker systems.

Q: What upstream equipment is the CA1202 designed to work with?

A: The CA1202 accepts balanced line-level signals from commercial DSPs, zone controllers, matrix mixers, and mixer amplifiers with balanced line outputs. It functions as the amplification endpoint in structured commercial AV system architectures.

Q: Is the CA1202 quiet enough for conference room installation?

A: Yes. Fanless convection cooling produces no mechanical noise during operation, making the CA1202 suitable for conference rooms, private offices, and other noise-sensitive commercial spaces.

Q: How does the high-pass filter help in commercial installations?

A: The switchable 80Hz high-pass filter removes low-frequency content below 80Hz from the amplifier output. This protects small commercial ceiling and pendant speakers from reproducing bass frequencies they cannot handle, reducing distortion and preventing driver damage.
