Quality and ease of portable recording
About the same size and construction of a first-generation Nintendo Game Boy, the Sony PCMM10 series of portable recorders (the "R" distinction means Red color; "B" for Black) is the perfect companion to any sound recordist/hobbyist capturing audio out on the field. With built-in 4 GB storage capacity, added with a 16 GB microSD chip gives me the freedom to record at will and for what feels like forever. Frequency response of 20 Hz to 40 kHz (Line in) @ 96KHz coupled with very user-friendly controls like a fluid REC LEVEL knob and MIC SENS (ATT) switch make it easy to attenuate high amplitude situations or pickup faint sounds (high sensitivity mode). I recently started to utilize the T MARK (track mark) button during non-interrupted recording to navigate more efficiently during playback as opposed to search/scanning via FFWD/RWD buttons. The PCMM10 is top quality you can only expect from Sony and at a decent price.
