Q1. What should I do if my in-ear monitoring keeps cutting out?

Wireless channels work like roads—when too many devices share the same frequency, interference or dropouts may occur.

Please try the following steps:

  • Change the wireless channel
    The ES-10T provides four channels (A / B / C / D). Switch channels to find one with less interference.

  • Avoid interference sources
    EverSync operates in the 5.8 GHz band. Avoid placing the system near Wi-Fi routers or other 5.8 GHz wireless devices.

Q2. What is the AUX IN on the ES-10R receiver used for?

The 3.5 mm TRS AUX IN on the ES-10R allows you to add a third audio source directly into your headphones.

Notes:

  • Volume must be adjusted on the playback device

  • Audio from AUX IN is not sent to speakers

  • Audio from AUX IN is not recorded via USB Audio

Typical use cases:

  • Personal click track

  • Reference tracks from a mobile phone

Q3. Why is the volume very low when using a dynamic microphone with EverSync?

EverSync IEM does not include a built-in microphone preamp.
Dynamic microphones produce low-level signals and require pre-amplification.

Correct signal flow:

  • Microphone → Preamp or mixer

  • Send a line-level signal into EverSync

Q4. How can I troubleshoot noise during use?

Noise is usually related to power or cabling. Please check the following:

  1. Power source (ground noise)

    • Avoid powering multiple devices from the same power bank or extension

    • Try a different power source to prevent ground loops

  2. Cables

    • Check for oxidation, damage, or poor shielding

    • Test with alternative cables

  3. XLR Ground Lift

    • When using XLR input on the ES-10T

    • Try enabling the Ground Lift switch

Q5. How do I power the ES-10T, and what do the indicator lights mean?

Power options (choose one):

  • 9V DC power supply

  • USB Type-C power

When powered successfully, the display will show the CloudVocal startup animation.

Indicator lights:

  • Red: Mute mode ON

  • Blue: Mute mode OFF

  • Blue flashing: Pairing mode

Additional notes:

  • 9V DC power provides better dynamic range

  • USB power offers higher convenience with slightly reduced dynamics

  • Choose based on your usage needs

Q6. Why does Input 2 have two input jacks, and how should I use them?

Input 2 provides two connectors:

  • 6.3 mm TS

  • 3.5 mm TRS

Usage:

  • Either input can be used independently

  • Both inputs can be used at the same time (signals are summed)

Note:
When using both inputs simultaneously, lower the 3.5 mm input level to avoid overload and distortion.

Q7. How do I adjust the monitoring balance?

The ES-10T supports two simultaneous audio inputs.

How to adjust:

  • Enter the Audio menu

  • Set the monitoring level and balance between the two inputs

Note:

  • These adjustments affect headphone monitoring only

  • Wired output levels and balance are not changed

Q8. Why do I hear distortion in my headphones?

The most common cause is input signal overload.

How to identify:

  • The level meter shows clipping, rough edges, or stays fully to the right

Solution:

  • Enter the Audio menu

  • Reduce the level of the corresponding input

  • Avoid keeping the meter at maximum for extended periods

Q9. How do I pair the ES-10T with ES-10R, and how do I add more receivers?

Pairing steps:

  1. Power on the ES-10T and wait for startup to complete

  2. Power on the ES-10R by holding the power button until the main LED flashes

  3. Enter the Radio menu on the ES-10T

  4. Activate pairing mode (PAIRING screen, blue LED flashing rapidly)

  5. Place the ES-10R close to the transmitter and press the pairing button

  6. When the receiver LED stays solid, pairing is complete

Notes:

  • Factory sets are pre-paired before shipping

  • When pairing mode is reactivated, previously paired receivers will reconnect automatically

Q10. How do I use the ES-10R USB Audio recording function?

EverSync uses broadcast transmission, allowing:

  • Multiple users to monitor simultaneously

  • Recording via ES-10R USB Audio at the same time

The ES-10R USB Audio function works like a standard audio interface.

Basic steps:

  • Confirm wireless pairing is completed

  • Use the original CloudVocal USB-C cable

  • Use the correct adapter if needed

  • Open a recording or video app

  • A purple LED indicates USB Audio is active

Mobile device compatibility:

  1. Automatically supported devices (e.g., iPhone)

    • Plug and play

    • Works with Voice Memos or Camera apps

    • Purple LED confirms success

  2. Manual activation required (some Android devices)

    • Enable USB Audio in system settings

    • Use apps that support external audio input

    • Recommended sample rate: 48 kHz

  3. Devices that do not support USB Audio

    • ES-10R cannot be used for recording

Important notes:

  • USB compatibility depends on the device, OS, app, and cable

  • Device-side USB Audio limitations are not covered under EverSync warranty or return policies

  • Please confirm device compatibility before purchase
