The Astone MX-1400-P is a powered analog mixer with 14 Mic/Line channels, featuring 14 XLR microphone inputs and corresponding line channels. Its built-in amplifier delivers 2 x 200 W at 8 Ω or 2 x 350 W at 4 Ω.

It provides 48 V Phantom Power for condenser microphones. Features include dual 7-band graphic equalizers and a 16-bit digital echo effect with an adjustable delay of 24.6–393.2 ms. The Master outputs include a balanced output with a +4 dB level and an impedance of approximately 600 Ω, and an unbalanced output with an impedance of approximately 75 Ω. The headphone output supports a 100 Ω impedance and delivers 3 mW at 32 Ω.
