Lab Gruppen CMA602 2 x 60W Commercial Mixer Amplifier with 8 Inputs

Product Overview

The Lab Gruppen CMA602 is a 2-channel, 2x60W commercial mixer amplifier with an integrated 8-input mixer section, designed for permanent installation in small commercial distributed audio systems requiring two independently controlled audio zones. It provides all the mixing and amplification needed for a compact dual-zone background music system in small retail areas, cafes, hotel corridors, and small offices in a single half-rack 1U unit. The CMA602 supports both low-impedance and 70V/100V constant-voltage speaker configurations.

Product Description

The CMA602 delivers 60 watts per channel across two independently controlled output zones, each switchable between low-impedance (4/8 ohm) and high-impedance (70V/100V) constant-voltage operation via rear-panel dipswitch. Its 8-input mixer provides six balanced mic/line Euroblock inputs and two additional line inputs, each with individual volume controls. Rear-panel input routing dipswitches allow each input to be assigned to Output A, Output B, or both zones simultaneously, enabling flexible zone coverage from a single compact unit. Priority muting on Input A automatically reduces background music when a paging or announcement signal is detected, supporting basic public address capabilities. Front-panel master volume, bass, and treble controls per output zone allow on-site adjustment by facility staff without rear-panel access. Fanless convection cooling ensures silent operation in noise-sensitive small commercial spaces including offices and hospitality rooms. Auto Ramp circuitry with a 20-minute sleep timer supports Energy Star energy efficiency for spaces with variable occupancy. The unit ships with joining brackets for rack, wall, or table mounting.

Frequently Asked Questions

Q: What is the difference between the CMA602 and the CMA1202?

A: Both are 2-channel 8-input commercial mixer amplifiers with the same feature set and form factor. The CMA1202 provides 120W per channel versus 60W per channel for the CMA602. Choose the CMA602 for smaller rooms with lower speaker tap totals, and the CMA1202 for larger spaces.

Q: Can the CMA602 drive 70V speaker lines in both zones simultaneously?

A: Yes. Each output channel is independently switchable to 70V or 100V constant-voltage operation via rear-panel dipswitch. Both channels can operate at 70V simultaneously, each supporting up to 60W of speaker tap load.

Q: How many 70V speakers can the CMA602 support per zone?

A: The total tap wattage on each output channel must not exceed 60W. With common 5W speaker taps, up to 12 speakers per zone could be supported within the power budget.

Q: Can all 8 inputs be sent to both output zones at the same time?

A: Yes. Each input can be independently routed to Output A, Output B, or both zones simultaneously using the rear-panel routing dipswitches.

Q: Is the CMA602 suitable for installation in a 19-inch rack?

A: Yes. The half-rack 1U unit includes joining brackets. Two units can be mounted side-by-side to fill a standard 1U rack space, or each unit can be rack-, wall-, or table-mounted individually.

Q: Does the CMA602 require any external power supply?

A: No. The CMA602 has an internal power supply and connects directly to a standard AC mains outlet. No external power supply or separate amplifier chassis is required.
