• Metal grid over woofer.
• One-year warranty.
• Interfacing: Four 1/4" TRS balanced line inputs with ?10 to +4dB
• sensitivity; one high-gain XLR mic input. 1/4" effects send and return jacks.
• Balanced XLR and unbalanced 1/4" line outputs. Standard IEC AC power in.
• Dimensions: 17.5" W x 12" D x 20.5" H, 37.8 lbs. Pros: Big, beautiful sound out of a reasonably compact cabinet.
• Cons: Controls on the back.
• Bottom Line: Straightforward and simple, the Sona 23c delivers exquisite sound quality and gracefully covers the audio bandwidth at volumes ranging from whisper-quiet to the threshold of pain.
• Its lone transgression is the placement of its controls and jacks, which are hidden in the back.
• XLR and 1/4" line-level outputs allow you to route your synth signals to another amp, the house P.A., or a recording console.
• The 23c's line output level is unaffected by adjustments to the master volume knob, which is the way it should be.
