Overview: The Zoom H4n Pro Handy Recorder is a portable 4-track digital audio
recorder with two analog inputs, two built-in microphones, and a stereo mic
input. It is ideal for recording audio for music, film, podcasting, and other
activities. The H4n Pro can record in either WAV or MP3 onto SD or SDHC memory cards. A 1.9"
backlit LCD screen (128 x 64 dots) shows the input levels of all four tracks, and lets you
maneuver through the menu with ease. The unit includes Steinberg Cubase LE and WaveLab LE music production software (free via download), and a hard plastic carrying case.
Main Inputs: The H4n Pro has two main inputs with
combo connectors that can accept either XLR or 1/4" balanced or unbalanced
plugs. The inputs can handle both mic-level and line-level signals with
ease, with internal switching contacts automatically detecting the signal type.
If you are using
condenser microphones, a simple menu option provides Phantom Power
(+24 or +48 volts) to the main inputs.
Built-in Microphones: The H4n Pro has two built-in condenser microphones
in an X/Y configuration. The mic capsules can be rotated to change the angle from 90° to 120°
for a wider stereo image. The microphones can record up to 140 dB SPL. The H4n
Pro uses the same mic preamps as the Zoom H5 and H6 recorders. The preamps offer
a lower noise floor (-120 dBU EIN) to allow you to record audio at lower volume
with less noise. A stereo 3.5mm input lets you connect an
external stereo microphone instead of the built-in mics.
Outputs: The H4n Pro features a 3.5mm unbalanced headphone/line output,
located on the side panel. You can monitor your recordings in real time with
headphones, or send a stereo signal to a camera, camcorder or other device. A Mini-B USB port (2.0
Hi-Speed compatible) allows you to directly connect the recorder to a computer
for transferring files. You can also use it as an audio interface, or as an SD
card reader for your computer.
File Types: The Zoom H4n Pro can record in the following
- WAV: Uncompressed WAV files can be recorded at 44.1kHz, 48kHz,
or 96kHz, and
16-bit or 24-bit. In 4CH mode, only 44.1/48kHz, 16/24-bit are available. WAV files are automatically time-stamped, making
them compliant with the Broadcast Wave Format (BWF). This allows you to
precisely synchronize the audio with on-screen action in video post
- MP3: MP3 files are compressed to reduce file size,
making them easier to store, upload and download. You can record only stereo
files in MP3. Available bit rates for recording MP3 include: 48, 56, 64,
80, 96, 112, 128, 160, 192, 224, 256, and 320kbps, plus VBR (variable bit rate).
Recording Modes: The H4n Pro offers the following recording modes:
- Stereo: In Stereo mode, you can select either Mic or Input 1
& 2 as the input source. This mode is convenient to record live performances,
acoustic instrument, voice, or lecture.
- 4CH: In 4CH mode, the unit records two stereo WAV
files: one stereo WAV file for the built-in microphones (or connected
external microphone) and one stereo WAV
file for the main inputs. This allows you to record both live sounds from the
built-in mic and direct instruments via the external inputs simultaneously.
- MTR: In MTR (multi-track recording) mode, you can record tracks in Mono or
Stereo from Input 1, Input 2, or the internal microphones. You can
combine them with tracks recorded in other modes or overdub additional
tracks. This mode allows you to record using effects, overdub recordings,
and use previously recorded sound files.
Stamina Mode: The Stamina mode is designed to save battery
power when recording under battery power, and when AC power is not available. It
is similar to Stereo mode, but has less functions. When recording in Stamina
mode, you can only record/playback in WAV 44.1kHz/16-bit and MP3 formats.
Activating Stamina mode requires flipping a switch under the battery compartment
door while the unit is turned off.
Recording Media: The H4n Pro records audio files up to 2 GB
in size, directly to SD and SDHC memory cards from 16 MB up to
32 GB. No SD cards are included. Typical recording time with a 4 GB SDHC card is
- WAV (44.1kHz/16-bit Stereo): 380 minutes
- MP3 (44.1kHz/128 kbps Stereo): 68 hours
Auto-Record: The Auto Record function can detect when the input level
surpasses a preset level, and can automatically start recording from
the recording standby mode. You can independently set a start level and a
stop level. Likewise, you can set the recorder to stop recording automatically
once the input level goes below a pre-determined level.
Pre-Record: The H4n Pro's Pre-Record function can help
prevent missing the beginning of an event. When Pre-Record is engaged, the H4n
continuously record in the background while you wait for the event to begin.
When you hit the Record button, the recorder keeps the previous two seconds
and adds it to the beginning of the file.
Mixer: In 4CH mode, you can use the mixer to adjust the
playback level and pan settings of two stereo files.
Effects: The unit has studio-grade effects modules, including
compression, limiting, low-cut filter, modulation, reverb, delay, and amp
- Preamp Module: The Preamp Module offers multiple
guitar, bass, and mic preamp effects.
- EFX Module: The EFX Module has compressor/limiter
effects, modulation effects, and delay/reverb effects.
Musical Tools: The H4n Pro offers some tools designed to help
- Tuners: The recorder can be used as a standard
chromatic tuner to help keep everyone in tune. In addition to chromatic,
there are other tuning modes such as guitar, bass, open A, open D, open E,
open G, and DADGAD. The tuner can be calibrated between 435 Hz to 445 Hz in
1 Hz intervals. The input source can come from the microphone or the line
- Metronome: The built-in metronome provides audible cues
to help you set and keep the tempo. The metronome can provide a pre-count of
1 to 8 beats, or a special pre-count. The tempo can be set between 40 and
250 beats per minute by 0.1 bpm. You can also adjust the level (0-10),
pattern (0/4--no accent, 1/4 to 8/4, and 6/8 time signatures), and sound
(bell, click, stick, cowbell, or Hi-Q).
- Karaoke: Music files can be converted into Karaoke form
for recording vocals or additional guitar sounds over those files. You can
apply center cancellation to the karaoke track, as well as variable key
Variable Pitch/Playback Speed: You can adjust the playback speed in a
range from 50% to 150% of normal, in increments of 5%, without changing the
pitch. In addition, you can raise and lower the pitch of the playback without
effecting the playback speed.
AB Repeat: The AB Repeat function allows you to continuously
and repeatedly play back a portion of the track. You can set marks at the
beginning and ending of the desired portion.
Optional Remote Control: The H4n Pro is compatible with the
optional RC4 wired remote control. The RC4 plugs into the side of the recorder
and gives you the following controls: Start/stop recording, fast forward,
rewind, change input source, and set recording and playback levels.
Mounting Options: The H4n Pro has a 1/4" threaded tripod mount
on the bottom. The optional
hot shoe adapter (sold separately), you can mount the recorder to the top of a DSLR or
shoe-equipped camcorder. A mic clip adapter (MA-2) is available that will let
you mount the H4n Pro on a standard microphone stand.
Power Requirements: The H4n Pro comes with two "AA"
batteries for powering the recorder. Either alkaline or nickel-metal hydride (NiMH)
batteries can be used. A segmented remaining battery charge indicator appears in
the display. You must correctly set the battery type in the menu to accurately
calculate remaining battery power. You can record continuously for about 6 hours
using alkaline batteries or about 8 hours using NiMH (2450mAh) batteries. In the
Stamina mode, battery life is extended to about 10 hours (alkaline) and 12 hours
(NiMH). When using the H4n Pro as an SD card reader or audio interface, you can
power the unit by USB bus power while connected to a computer. The optional Zoom
AD-14 AC adapter (5V 1A) is recommended for long recording or playback sessions.
Included Software: The H4n Pro comes with free download
licenses for Steinberg's Cubase LE music production software and WaveLab LE
audio editing software. Cubase LE and WaveLab LE work with Windows 7, 8/8.1, and 10, and Mac OS X
10.11, macOS 10.12 and macOS 10.13.
