Finnish Letu PAW-V digital recorder/pen (interview machine)

Detailed introduction
Two-way high-quality microphone
The built-in microphone adopts a differential pressure high-quality microphone, which can be adapted to recording in a variety of environments. The frequency response range of the microphone channel is ~, and it has strong directivity. It can collect the sound within the directional range very well and shield the noise.
High-quality front-end amplification circuit
This series of recording products has been committed to creating the best recording quality, and the built-in circuit adopts a multi-stage design. The built-in front-end amplification circuit allows this machine to achieve unprecedented sound quality. This circuit has a high signal-to-noise ratio and a large dynamic range. It amplifies the input signal while suppressing noise, better restoring the live sound, and making the recording clearer and more dynamic. Whether you're recording a session or recording a large symphony live, you can achieve perfect results.
Rich recording functions
Two recording templates
It continues the series of recording template concepts and breaks the limitations of fixed recording formats. You can set the recording according to your needs, especially suitable for people with special needs. In-demand musicians, journalists and other professionals. The recording format, color page frequency, and bit rate can be freely adjusted in the recording template.
,, multiple recording formats
Linear format recording has the highest fidelity level and excellent sound quality, but the file size is larger and the format file is smaller, which can meet your daily voice recording needs, such as in class records or general meeting minutes, etc.
Automatic gain control
The automatic gain control function can automatically adjust the gain according to the volume of the audio source. If the sound source volume is low, the level will be automatically increased to make the recorded sound clearer. When the sound source volume is too loud, the level value can be reduced so that it does not exceed the level limit.
Especially suitable for conference recording, it can effectively reduce the difference in sound size caused by different distances.
High-pass filtering
Can be used to cut off low-frequency sounds. You can use this function under appropriate circumstances to cut off low-frequency noises, such as wind noise, etc.
Close, you can record the sound of ~. Open, you can record the sound of >.
The function of adding mark points
can be used as recording segments or prompts, which can facilitate you to quickly find marked positions in long recording files later. Each recording file supports up to multiple points.
Voice-activated recording function
It has a voice-activated recording function, that is, it automatically detects the ambient sound source level during the recording process. During the recording process, if the level is lower than the preset level value, the recording will be paused, and when the ambient sound source level is greater than the set level value, the recording will be restarted. The voice-activated recording function can effectively save storage space.
Supports pre-recording in seconds at most
Turn on pre-recording, and the sound files within the set time will be dynamically saved in the cache, and automatically saved to the beginning of this file after the official recording starts, thus ensuring that the recording file is more accurate whole.
Peak Detection
The peak detection function can detect the current recording level. If the level is too high, the light will light up to remind you that the current level exceeds the limiter value and will be clipped. Please adjust the gain to keep the bar of the recorded program around the cue point to obtain the best recording experience.
Super long recording time
Card storage medium
Use /, support or larger capacity, which can fully meet your long-term recording needs.
Perfect playback enjoyment
Multiple equalizers
Built-in multiple equalizers, you can modify the playback sound effects by adjusting the gain value of each frequency band. Proper use of equalizer can make the sound rounder and have better effect.
When you use headphones to monitor recording files, you can use a variety of equalizers such as normal, bass, jazz, headphones, dance music, industrial, rock, pop, classical, etc.
Smart Level
The unique smart level function can dynamically monitor the level value of the playback file during the volume adjustment process, increase the smaller level while ensuring that the larger level will not be overloaded. Thus maintaining perfect sound quality. The smart level function uses digital dynamic amplification to amplify the playback level to twice the original level, giving you a clearer experience.
Built-in speakers
Built-in high-fidelity speakers on the back of the fuselage, you can share your recording results anytime and anywhere.
