The LINO series are column speaker series designed for a wide variation of general-purpose applications in acoustic difficult environments, ranging from speech and announcement applications to background music systems. Typical applications are houses of worship, auditoria, presentation rooms, public transportation hubs, … and many more. They are solid constructed using solid aluminum materials and finished through a rigid finely perforated front grill.

The LINO4 column speaker consists of 4 x 2” low/mid-frequency drives with a 1” central positioned tweeter for the high frequencies. It reaches a power handling of 20 Watt, while a multi-tapping line transformer allows it to be connected in 70V/100V public address systems with power taps for 20W, 10W and 5W (2.5 W for 70V use only). It offers solutions for uniform acoustic performance in any type of system in reverberant venues, while reducing echo and microphone feedback to optimizes the intelligibility of music & speech.

Mounting is done through an L-shaped bracket on top and bottom, offering optimal flexibility for fixation and directional placement. The distance from the speaker to the wall is 10mm, while it can be vertically inclined 4°. Connections are made through multi-tapping terminal block connector and A multi-tapping line transformer allows them to be connected to 70/100V public address systems with various power tapping settings, while connections in low impedance systems are also possible.

*Given dispersion values are the average beamwidth within the 1 kHz – 4 kHz frequency range (-6 dB - 1/3 oct) , which are critical for the speech intelligibility in the main application field of these loudspeakers.
