Lab Gruppen CPA1201 120W Commercial Mixer Amplifier with 5 Inputs, Bluetooth

Product Overview

The Lab Gruppen CPA1201 is a single-channel, 120W commercial mixer amplifier with a 5-input mixer section, integrated Bluetooth streaming, and a USB media player, designed for single-zone commercial distributed audio in small to medium commercial spaces. It combines source selection, mixing, and amplification in a compact half-rack 1U unit, making it an efficient solution for background music in small retail areas, hotel rooms, offices, and conference rooms where a single audio zone is sufficient. The CPA1201 supports both low-impedance and 70V/100V constant-voltage speaker systems.

Product Description

The CPA1201 delivers 120 watts into a single output channel, switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation. Its 5-input mixer includes balanced mic/line Euroblock and line-level RCA inputs with individual volume controls for flexible source management. Integrated Bluetooth receives wireless audio from mobile devices, and the USB media player with LCD display provides standalone playback from USB storage without a dedicated source component. Front-panel master volume, bass, and treble controls allow facility staff to adjust audio levels without rear-panel access. Priority muting on Input A automatically reduces background music when a paging or announcement signal is detected, making the CPA1201 suitable for retail, hospitality, and small office public address applications. Fanless convection cooling ensures silent operation, and Auto Ramp circuitry with a 20-minute sleep timer keeps operating costs low in spaces with variable daily occupancy. The unit ships with joining brackets for rack, wall, or table installation.

Frequently Asked Questions

Q: What is the difference between the CPA1201 and the CPA1202?

A: The CPA1202 is a 2-channel unit delivering 120W per channel across two independent zones. The CPA1201 combines all 120W into a single output channel for applications where only one speaker zone is needed.

Q: Can the CPA1201 drive a 70V speaker system?

A: Yes. The output channel is switchable to 70V or 100V constant-voltage operation via rear-panel dipswitch, driving standard distributed speaker systems with individual tap transformers at each speaker.

Q: What is the maximum number of speakers the CPA1201 can support on a 70V system?

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

Q: Does the CPA1201 include a microphone input for paging?

A: Yes. The balanced mic/line Euroblock inputs accept microphone signals. Input A includes configurable priority muting, which reduces all background sources when a paging microphone signal is detected.

Q: Is the CPA1201 suitable for wall mounting?

A: Yes. The included joining brackets support rack, wall, and table mounting, giving installers flexibility to position the unit close to the speaker zone or in a central equipment rack.

Q: Can Bluetooth and USB sources both be routed to the output zone?

A: Bluetooth and USB are selectable sources on the media player section. Only one can be active at a time. The active media source is treated as one input among the 5 available, subject to the same volume control and priority muting as other inputs.
