·         XLR input connectors for balanced system configuration.

·         RCA input connectors for unbalanced system configurations.

·         Dual Speaker Output Terminals on each channel for bi-wiring applications.

·         User selectable switching between balanced and unbalanced connections.

·         Transformer coupled inputs provide universal compatibility with other components and eliminate ground loop noise and EMI.

·         High efficiency ICEpower@ power conversion technology generates high output power with very little heat.

·         Fully-balanced topology implemented in both input and output circuitry.

·         Power Factor Correction (PFC) in power supply reduces AC line harmonic noise pollution and increases AC line power utilization to 99%.

·         Proprietary switch-mode power supply technology ensures consistent performance under all operating conditions.

·         12V remote ON/OFF remote power switching via 1/8” jack on rear panel.

·         Standby power mode reduces warm-up time.

·         CE approved speaker output terminals require no tools for secure, low resistance connections.

·         Fail-safe operation provided by user-resetable thermal circuit breaker located on rear panel.

·         Quiet, transient-free operation during power ON/OFF and input configuration switching.

·         Selectable overall gain of 26 or 32 dB.

·         Ultra-low resonance, structurally rigid chassis, precision-machined from a solid block of aircraft grade 6061-T6 aliminum.

·         3-point self-leveling chassis support.
