Frequently Asked Questions
What is a 4-channel installation amplifier used for?
A 4-channel installation amplifier like the Lab.Gruppen E 20:4 distributes audio power across multiple zones or speakers in fixed installations such as conference rooms, retail spaces, and commercial venues. The multi-channel design allows independent control and power delivery to different audio zones simultaneously.
Can the Lab.Gruppen E 20:4 work with 70V systems?
Yes, the E 20:4 supports both 70V and 100V constant-voltage operation, making it ideal for distributed audio systems commonly used in commercial installations. It also supports direct impedance modes (2Ω, 4Ω, 8Ω, 16Ω) for flexible speaker configurations.
What does Class-D amplifier technology mean?
Class-D amplifier technology uses high-frequency switching to deliver efficient power conversion with minimal heat generation. Combined with IntelliDrive Energy Efficient Amplifier design, the E 20:4 reduces operational costs and cooling requirements in installation environments.
Is the Lab.Gruppen E 20:4 suitable for rack mounting?
Yes, the compact form factor of the E 20:4 is designed for professional rack mounting in A/V installations, making it ideal for control rooms, broadcast facilities, and integrated audio-visual systems where space efficiency is critical.
