The OM SYSTEM LS-P5 is a compact linear PCM audio recorder built around a three-microphone TRESMIC II system, capturing up to 24-bit / 96 kHz audio. Designed for long, unattended recordings, it runs for extended periods on two AAA batteries while remaining small enough to pocket or mount. Bluetooth control, onboard scene presets, and in-recorder editing make it easy to set levels, monitor sound and tidy files without opening a laptop.

FAQs
What makes the LS-P5 different from typical two-mic recorders?
The LS-P5 uses a three-microphone TRESMIC II system rather than the more common two-mic layout. This allows finer control over directionality, with 21 selectable steps that let you narrow or widen the pickup depending on distance and background noise. In practice, it gives you more control over focus without needing external microphones. It also helps maintain consistent tonal balance across quiet and loud sources.
Can I control and monitor recordings remotely?
Yes. Built-in Bluetooth lets you control the recorder from an Android or iOS phone using the OM SYSTEM app. You can start and stop recording, adjust mic direction, change levels and monitor status without touching the unit. This feature is handy when the recorder is mounted on a camera or a tripod, or placed out of reach.
Is it suitable for very loud sound sources?
The LS-P5 handles sound pressure levels up to 125 dB SPL, which is unusually high for a recorder of this size. This allows it to capture loud music, machinery or live events without distortion. The built-in limiter and manual level controls help keep peaks under control when conditions change suddenly.
Can I edit recordings without a computer?
Yes. The recorder includes trimming, file division, fade-in and fade-out, and basic noise reduction tools directly onboard. Playback features such as voice balancer and normalised playback also make it easier to review long recordings. For quick turnaround work, you can prepare usable audio without transferring files first.
How long can it record on batteries?
Battery life depends on format and settings, but the LS-P5 is designed for extended sessions. Even at high-quality PCM settings, it can record for many hours, whereas lower-bit-rate MP3s stretch this significantly. Using standard AAA batteries makes it easy to keep running during long projects or travel.
Does it support external microphones or line sources?
Yes. A 3.5mm mic/line input allows you to connect external microphones or line-level feeds from mixers or other devices. This adds flexibility when you need a specific mic character or want to take a direct feed, while still using the LS-P5 as the main recorder.
