Musical applications for the H4N include the ability to use the device as a multi-track (four-channel) recorder; the device also includes tools like a built-in tuner, metronome and effects processor for line-level instruments like guitars. The H4n has a rubberized casing, [1] a larger screen and buttons that differ from the H4. The H4n (with ...
The H4 is shorter than a pencil Field recording with H4 on a simple tripod H2 and H4 with 10 eurocents for scale. The H4 Handy Recorder is a handheld digital audio recorder from Zoom, featuring built-in condenser microphones in an X-Y stereo pattern, [1] priced from around US$280 depending upon memory capacity as of 2011.
The amplifier's output impedance may be matched to the characteristic impedance of the transmission line. Line drivers are commonly used within digital systems, e.g. to communicate digital signals across circuit-board traces and cables. [1] In analog audio, a line driver is typically used to drive line-level analog signal outputs, for example ...
Voltage vs. time of sine waves at reference and line levels, with V RMS, V PK, and V PP marked for the +4dBu line level. A line level describes a line's nominal signal level as a ratio, expressed in decibels, against a standard reference voltage. The nominal level and the reference voltage against which it is expressed depend on the line level ...
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
When connected to a host computer via USB, the H2 can act as a microphone, audio input (with microphone or line input) and output device with stereo line output. It can also be used as a USB file storage device. Typical prices in the United States as of 2011 were around US$350 for the H4n and around $200 for the H2 and H2n. [9]
The Zoom H2n is a portable digital sound recording device manufactured by Zoom and was introduced in 2011 [1]. It is the successor of the Zoom H2 recorder. The Zoom H2n has four microphone capsules (including one bidirectional) built inside it.
X10 controllers: A simple controller (bottom left), a radio controller (top center), and an original controller (bottom right) usable with an ultrasonic remote control. X10 controllers range from extremely simple to very sophisticated. The simplest controllers are arranged to control four X10 devices at four sequential addresses (1–4 or 5–8).
