HD9 4-Pair + HP4 + RCM01 4-Pack

This bundle builds a monitoring and recording setup for four people at once, combining the HD9/HP4 headphone pack with four RCM01 condenser microphones. Each HD9 headphone uses 45mm neodymium drivers in a closed-back design with a 10Hz to 26kHz frequency response, and the included HP4 amplifier drives all four from one source with independent level control and mono summing per channel, plus balanced outputs for daisy-chaining more amps if needed.

On the microphone side, each RCM01 brings a 25mm diaphragm and a unidirectional cardioid pattern that focuses on the sound source while rejecting noise from the sides and rear, backed by a low 18dBA noise floor for clean recordings even in quiet rooms. A metal shock mount comes with every microphone, and each ships with both a phantom-power XLR cable and a 3.5mm-to-XLR cable, so it works with a mixer or connects directly to a computer sound card. With four headphones, one amplifier, and four microphones in the same order, this bundle is built for a four-person podcast, a small vocal group, or any session where several people need to record and monitor at the same time.
