No noticeable scratches or stains. Only recording and playback with the built-in microphone have been checked. Linear PCM allows for the recording of pure sound without compressing the sound source, allowing for the recording of each and every original sound in its entirety, realistically capturing even the expression and presence of the interweaving of sounds. Recording at 96kHz 24-bit, which is the standard format used in recording studios, enables recording with sound quality that exceeds the density of DAT (48kHz 16-bit) and music CDs (44.1kHz 16-bit). In addition, the recording has a flat frequency response from low to high frequencies, enabling recording with rich sound quality. The circuit board consists of four types of circuits: input circuits, output circuits, digital circuits for recording, and power circuits. By placing independent power supplies for each circuit, current interference is prevented and noise generation is suppressed. As a result, a high signal-to-noise ratio of 93 dB or higher is achieved. Furthermore, the output signal reproduces the input signal with high precision, enabling linearity of nearly -96dB. Two AD converters are used per channel to ensure that the signal is always 12 dB lower than normal audio. When an excessive input occurs, the recording data is replaced back to that point. This provides a negative limiting time constant, which is not possible with analog, and prevents sound distortion. Sony’s proprietary “Super Bit Mapping” technology is incorporated. This technology dramatically expands the auditory dynamic range by reducing noise, which is particularly noticeable within the human audible bandwidth, and incorporates the equivalent of 20 bits of information into 16 bits to improve the sound quality to an even finer level. Filters and attenuates low frequency sounds below 75Hz/150Hz to reduce noise from air conditioning equipment and outdoor wind noise. Built-in high-sensitivity electret condenser microphone with an output sensitivity of approximately -35.0 dB/Pa 1 kHz. It has excellent frequency response and allows recording with rich and extended sound quality in the mid and low frequency range. The microphone is movable, allowing the user to select from two positions with different sound collection ranges. For example, the X-Y position can be selected for recording a solo performance or a 2-3 person session where the sound source is close to the microphone. This gives a natural and deep stereo effect. For recording a large group performance such as an orchestra or chorus in a large space, select the “Wide Stereo Position”. This position provides a realistic and expansive sound. The linear PCM format, which does not compress sound, allows for long recording times with the rich and delicate sound quality of original sound as it is. 1 hour and 55 minutes of recording is possible on the unit, even at 96 kHz 24-bit sound quality, which exceeds DAT (48 kHz 16-bit). When used in combination with Memory Stick PRO-HG Duo , even longer recording time is possible. When the “prerecord function” is set to ON and recording is paused, 5 seconds of sound is always stored in memory, so that when the REC button is pressed, recording starts from the previous 5 seconds. This allows you to record birdsongs and other sounds before they start singing, so you will never miss an opportunity to record at a moment’s notice. Recording level can be adjusted with the REC volume while checking the peak meter on the LCD display and the maximum peak value. The peak LED lights green for proper level (-12 to -1 dB) and red for over level (-1 dB or more) according to the input signal of each left and right channel. Equipped with DPC (Digital Pitch Control), which allows only the speed to be changed while keeping the pitch natural. For example, MP3-format music files can be imported and listened to at a pitch close to natural pitch, making it ideal for checking performance practice. In addition, it is equipped with a high-performance headphone amplifier with excellent frequency response. It can also be used as a high-quality music player. The body is made of a combination of magnesium (sides) and aluminum panels (front and back). The lightweight and highly rigid body is resistant to vibration and comfortable for outdoor recording. The unit can also record for approximately 24 hours with four AA alkaline batteries. An AC adapter is also included for convenient indoor recording. 44.1 kHz 16-bit recording (without monitoring).
