Lab Gruppen CA602 2 x 60W Commercial Amplifier with Energy Star Certification

Product Overview

The Lab Gruppen CA602 is a 2-channel, 2x60W commercial power amplifier with Energy Star certification, designed for permanent installation as a dual-zone amplification endpoint in small commercial distributed audio systems. It accepts balanced analog signals from an upstream DSP, zone controller, or commercial mixer and delivers 70V/100V or low-impedance audio to two independent speaker zones, providing reliable two-zone amplification in a compact, Energy Star certified half-rack unit. The CA602 is the entry-level two-channel model in the CA series and is well suited for small retail areas, hotel rooms, small offices, and compact commercial spaces.

Product Description

The CA602 provides 60 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, and mixer amplifiers. Rear-panel dipswitches configure output voltage and input gain per channel, providing straightforward installer setup without software. A switchable 80Hz high-pass filter per channel protects small commercial ceiling and pendant speakers from low-frequency content. Auto Ramp circuitry activates the CA602 on signal detection and enters sleep mode after 20 minutes of inactivity, maintaining Energy Star compliance and reducing operating costs. Fanless convection cooling ensures completely silent operation in hotel rooms, small offices, and other quiet commercial spaces. The unit ships with joining brackets for rack, wall, or table mounting as a 1U half-rack unit. The CA602 is an appropriate low-power two-zone amplification endpoint in DSP-based commercial AV systems where mixing and routing are handled upstream.

Frequently Asked Questions

Q: What is the difference between the CA602 and the CA1202?

A: Both are 2-channel Energy Star commercial power amplifiers with the same form factor and features. The CA1202 provides 120W per channel versus 60W per channel for the CA602. Choose the CA602 for smaller rooms and shorter 70V speaker runs, and the CA1202 for larger spaces with more speakers.

Q: Does the CA602 include a mixer?

A: No. The CA602 is a power amplifier with one balanced input per channel. For multi-source mixing, pair it with a Lab Gruppen CM41 or CM82 mixer, or use a CMA series mixer amplifier instead.

Q: Can the CA602 power 70V speaker systems in both zones simultaneously?

A: Yes. Each output channel is independently switchable to 70V or 100V constant-voltage operation, so both channels can drive 70V speaker systems simultaneously, each supporting up to 60W of total speaker tap load.

Q: How many ceiling speakers can each CA602 channel support at 70V?

A: Total speaker tap wattage per channel must not exceed 60W. With 5W speaker taps, up to 12 speakers per channel; with 8W taps, up to 7 speakers per channel.

Q: Is the CA602 suitable for wall mounting?

A: Yes. The included brackets support wall mounting, allowing the CA602 to be installed close to the speaker zone to minimize speaker cable runs while an analog balanced cable carries signal from upstream equipment.

Q: Does the CA602 power down automatically during periods of inactivity?

A: Yes. Auto Ramp monitors the input signal level. After 20 minutes without an input signal, the CA602 transitions to a low-power sleep mode, then resumes normal operation automatically when signal returns.
