Cool and Powerful

The Meridian 258 is our dedicated rack-mount Eight Channel Power Amplifier. This powerful, high performance, cool-running Class D amplifier is suitable for a wide range of applications. At only 1U high, the compact 258 is a category changing amplifier; bringing Meridian high resolution sound quality to every zone it powers.

Featuring a highly efficient, cool and fan less construction, the Meridian 258 provides a truly ‘fit and forget’ solution when driving multiple zones. An audiophile approach has been taken to the 258’s component selection, resulting in a level of performance typically associated with power amplifiers offered at a significantly higher price.

Key Features:

• Delivers >100W per channel into 4 ohms or >70W per channel into 8 ohms.
• Short signal path construction delivers excellent isolation between the 258’s eight channels.
• Linear power supply provides isolation from the AC supply to deliver both unbeatable audio performance and reliability.
• High efficiency (>95%) Class D amplifiers generate minimal heat, making the 258 a cool-running and stackable solution.

HIGH POWER FROM ALL CHANNELS
Delivers >100 watts per channel into 4 ohms, or >70 watts per channel into 8 ohms, regardless of how many channels are driven simultaneously.

EXEMPLARY SOUND QUALITY
Short signal path construction is combined with extremely high isolation between the 258’s eight channels.

LINEAR POWER SUPPLY
A linear power supply using a massive toroidal transformer delivers both unbeatable audio performance and reliability.

COMPACT DESIGN
Measuring only 1U high, the 258 is a compact unit that requires minimal space in-rack.

SILENT OPERATION
Designed to run within temperature limits with no need for internal cooling fans.

ADVANCED CLASS-D IMPLEMENTATION
Highly-efficient Class-D amplifiers with post-filter feedback are extremely well isolated from each other.
