Lab Gruppen C 88:4 — buyer FAQs
What is the Lab Gruppen C 88:4 and what is it designed for?
The Lab Gruppen C 88:4 is an 8,800 Watt, 4-channel amplifier built specifically for installation applications. It delivers up to 2,200 Watts per channel into 2 Ohms and sits in a compact 2U rackmount chassis. NomadLink network connectivity allows monitoring and control via DeviceControl software, making it suited to fixed installations where remote management and reliable long-term operation are priorities.
Who makes the C 88:4 and where does it sit in the Lab Gruppen range?
Lab Gruppen is a Swedish manufacturer founded in 1979, focused on professional power amplifiers for touring and installed sound and part of the Music Tribe group. The C 88:4 is the flagship of the C Series, positioned as the most powerful single-frame, 4-channel installation amplifier in that line, delivering 4 x 2,200 Watts into 2 Ohms.
What output configurations does the C 88:4 support across different load impedances?
The C 88:4 offers flexible output across a wide range of loads: 4 x 2,200 W into 2 Ohms, 4 x 2,100 W into 4 Ohms, 4 x 1,250 W into 8 Ohms, 4 x 650 W into 16 Ohms, 4 x 2,200 W into Hi-Z 70 V, and 4 x 1,700 W into Hi-Z 100 V. Selectable gain, scalable Voltage Peak Limiter and bridge-mode operation allow further configuration for specific installation requirements.
What technology does the C 88:4 use to balance audio quality with efficiency?
The C 88:4 uses a Class-TD output stage, which is designed to deliver Class-A/B audio quality while operating at Class-D efficiency levels. A Regulated Switch Mode Power Supply maintains consistent power output regardless of mains fluctuations. The Intercooler copper cooling system dissipates heat to support extended peak output, and a removable dust filter grille assists airflow in long-term install environments.
What should I check when buying a used C 88:4?
When buying a second-hand C 88:4, confirm that all four channels are fully functional across the impedance loads relevant to your installation, that the NomadLink network monitoring operates correctly, and that the Intercooler cooling system and dust filter are intact. Check the condition of the Phoenix connector inputs and barrier strip outputs. Used units on 10K Used carry a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide.
