Lab Gruppen CA1201 120W Commercial Amplifier with Energy Star Certification

Product Overview

The Lab Gruppen CA1201 is a single-channel, 120W commercial power amplifier with Energy Star certification, designed for permanent installation as a single-zone amplification endpoint in commercial distributed audio systems. It accepts a balanced analog signal from an upstream DSP, zone controller, or mixer and delivers 70V/100V or low-impedance audio to a commercial speaker system, providing straightforward amplification without the added cost of an integrated mixer. The CA1201 is fanless, convection-cooled, and suitable for installation in offices, hotel spaces, conference rooms, and other noise-sensitive commercial environments.

Product Description

The CA1201 provides 120 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, matrix mixers, zone controllers, and other professional audio source equipment. Rear-panel dipswitches control output voltage selection and input gain, allowing straightforward configuration without software or front-panel menus. An 80Hz switchable high-pass filter protects commercial ceiling and pendant speakers from damaging low-frequency content. Auto Ramp circuitry activates the CA1201 automatically when input signal is present and enters sleep mode after 20 minutes of inactivity, reducing energy consumption in spaces with variable occupancy and supporting Energy Star certification. Fanless convection cooling eliminates all mechanical noise, making the CA1201 suitable for installation in occupied offices, hotel rooms, conference rooms, and other quiet commercial spaces. The unit ships with joining brackets supporting rack, wall, or table installation as a 1U half-rack unit. As a pure power amplifier, the CA1201 is best deployed as part of a structured commercial AV system where a separate DSP or zone controller handles signal routing and mixing.

Frequently Asked Questions

Q: Does the CA1201 include a mixer or source selection?

A: No. The CA1201 is a single-input power amplifier. For multiple sources or paging capability, pair it with a commercial mixer such as the Lab Gruppen CM41 or CM82, or use a CMA or CPA series mixer amplifier instead.

Q: What is the difference between the CA1201 and the CA1202?

A: The CA1202 is a 2-channel unit delivering 120W per channel across two independent zones. The CA1201 provides 120W into a single output channel for single-zone applications.

Q: Can the CA1201 power a 70V speaker system?

A: Yes. The output is switchable to 70V or 100V constant-voltage operation via rear-panel dipswitch. Standard 70V tap transformers at each speaker are required.

Q: What upstream equipment does the CA1201 work with?

A: The CA1201 accepts balanced line-level signals from DSPs, zone controllers, matrix mixers, and other commercial audio equipment with balanced analog outputs. It is commonly used as an amplification endpoint in structured commercial AV systems.

Q: Is the CA1201 fan-cooled?

A: No. The CA1201 uses fanless convection cooling with no moving parts, providing completely silent operation suitable for hotel rooms, private offices, and conference rooms.

Q: How many speakers can the CA1201 drive on a 70V circuit?

A: The total wattage of all speaker tap settings on the 70V output must not exceed 120W. With 8W speaker taps, up to 15 speakers could be connected within the power budget.
