Earthworks SR30 Cardioid Condenser Instrument Microphone
The SR30 is a multi-purpose cardioid condenser built for instrument miking, with a consistent cardioid pattern that holds its shape across the whole frequency range and delivers more than 30 dB of off-axis rejection. That combination captures a source cleanly while keeping the rest of the stage out of the channel, so it excels on guitar amps, drums, percussion, and acoustic instruments.
A lightning-fast transient response resolves sharp attacks and subtle detail, and the wide 20 Hz to 30 kHz range keeps the tone open and natural. It handles 139 dB SPL and runs on 24 to 48 V phantom over XLR. Available as a single mic or a factory-matched pair for stereo work - select above.
