Terms used in this manual

Podcast

This is one way of sharing audio files on the Internet. Content that is easy to listen to casually on smartphones, computers and other devices can be made and then distributed through the Internet.

Audio interface

This is a device that can be used to input audio from a mic to a computer, smartphone or tablet and also output audio from that device to headphones, for example.

Background music can be added to podcasts by outputting music and other sound played back on a computer, smartphone or tablet to the P2.

AIF Mix Minus

Phone guests can participate remotely in podcast recording by using the P2 as an audio interface for a computer, smartphone or tablet.

By enabling the AIF Mix Minus function during remote participation, input from the call participant will not be returned to them, preventing feedback on their end.

Podcasting flow

● Preparations

  • Connect USB mics and headphones. (→ Making connections)

    • By using one USB mic for each person, levels can be adjusted according to the volume of each individual, enabling recording that is easier to understand.

    • Adjust the distances between the USB mics and the participants. Then, set the input levels to suit the volumes of the individual voices so they can be recorded at stable levels.

    • In addition to checking the inputs from USB mics, headphones are necessary to hear the voices of guests participating remotely and sounds played back from computers, smartphones and tablets.

  • Check the level of the background music being recorded.

● Measures for environmental noise at recording locations

  • Blowing noise caused by wind can be reduced by putting windscreens on USB mics. For other environmental sounds, adjust the USB mics so that they are oriented away from the sound sources.

  • Mute channels that are not being used to prevent them from picking up noise. (→ Muting USB mics)

  • Touching the USB mics or power cables being used during recording could cause a rustling noise. Use mic stands and keep cables organized. Noise could be picked up if USB and power cables are too close together.

  • By turning on the AI NOISE REDUCTION function of the P2, vibrations, wind and other environmental noises picked up by USB mics can be reduced. (→ Adjusting the sound)

● Recording themes

Confirm the content of the discussion with the participants, ready reference materials and make other preparations in advance to enable recording conversations with a good rhythm.

● Speaking tips

While focusing on speaking clearly, try to keep sibilant (hissing “s”) and fricative (popping “p”) sounds from becoming too loud.

● Background music and other sounds

Add excitement to programs by playing music, effects and other sounds from a computer, smartphone or tablet. (→ Using as an audio interface)

● Public release

Recorded files can be transferred by connecting the P2 to a computer, smartphone or tablet. (→ Transferring files to computers) 
Upload them to the hosting service* or server being used.

    Confirm that USB mics are connected using USB cables that support data transfer.

    Connect headphones to the headphone jacks on the P2.

  • Check the orientations and level settings of the USB mics.

  • Confirm that the headphone volume and the USB mic levels are not too low. (→ Adjusting the monitoring level, Adjusting USB mic levels)

  • Check the mute setting. (→ Muting USB mics)

Monitored sound is distorted

  • Confirm that level indicators are not lighting to their highest levels. If they are lighting, use the (INPUT LEVEL 1) and (INPUT LEVEL 2) knobs to adjust the levels of the USB mics. (→ Adjusting USB mic levels)

  • Use the (HEADPHONE VOLUME) knob to adjust the headphone volume.

Recorded audio is too loud, too quiet or silent

  • Use the (INPUT LEVEL 1) and (INPUT LEVEL 2) knobs to adjust the levels of the USB mics. (→ Adjusting USB mic levels)

  • Adjust the levels on the USB mics.

  • If the input sound is too loud, speak further away from the USB mic.

  • Confirm that the (MUTE 1) and (MUTE 2) buttons are not lit and that the mics are not muted.

Recording is not possible

  • Confirm that the USB mics and the computer, smartphone or tablet are recognized.

    If the LEVEL indicators are blinking red, the sampling frequency, bit depth or channel count of the USB mic is not supported.

    Communication with the USB mic could also have been interrupted.

    See the ZOOM website (zoomcorp.com/help/p2) for information about USB mics that have been confirmed to work with this unit.

  • Confirm that the microSD card has open space. The available recording time can be checked on the ZOOM P2 Editor screen. (→ Checking the microSD card state)

  • Confirm that a microSD card is loaded properly in the card slot. (→ Inserting microSD cards)

The recorded sound breaks up

  • Use the P2 to format the microSD card. (→ Formatting microSD cards)

  • We recommend using microSD cards that have been confirmed to operate with this recorder.

    See the ZOOM website (zoomcorp.com/help/p2) for information about microSD cards that have been confirmed to work with this unit.

Other trouble

Not recognized by a computer, smartphone or tablet even though a USB port is connected to it

Date and time data for recorded files are very inaccurate

  • If power is not supplied by a USB AC adapter or batteries for a long time, date and time settings will be reset. Use a USB cable (Type-C) to reconnect the P2 with a computer, and launch ZOOM P2 Editor to acquire date and time data. (→ Setting the date and time)

Battery operation time is short

Making the following settings could increase the battery operation time.

  • Set the type of battery used correctly. (→ Setting the type of batteries used)

  • Disconnect unnecessary cables from connectors.

  • Due to their characteristics, using rechargeable nickel metal hydride batteries (especially high-capacity ones) or lithium batteries should enable longer use than alkaline batteries when power consumption is high.

All LEVEL indicators are blinking

If a USB mic with high current consumption is connected, all LEVEL indicators will blink and “USB mic uses too much power. Please power off.” will be output as audio guidance.

  • Turn the P2 power off and disconnect the USB mic.

  • Use a separate AC adapter, for example, to supply power when connecting USB mics with high current consumption.
