Safety Precautions
!
!
Listening with earphones for extended periods of time can cause serious damage to hearing.
-
Volume of the unit is xed to the maximum size and is congured to be adjusted on the input device.
- Be sure to check the volume position of the input device before using.
Please refrain from the use in case of thunder or lightning.
- There is a risk of re or electric shock caused by lightning.
USB power must be for DC5V.
- A power supply must be genuine and otherwise, it may cause severe noise.
Do not use the earphones when driving (bicycles, motorcycles, cars, etc.) or walking.
- May be a cause of an accident and may be illegal depending on a country and an area.
Use only accessories and components specified by the seller or manufacturer.
- In case of non-specied accessories and components, there is a risk of injury, overheating, re and so on.
- For an injury or accident caused by damage and malfunction of the product due to any changes or modications
by users, the seller or the manufacturer cannot take responsibility.
Since this unit is an electronic device to which power is supplied, do not handlewith wet hands
when handling.
- This may result in a serious injury due to electric shock when handling with wet hands.
Since this unit should transmit the audio signal wirelessly, it causes interference with the
reception to be the impediments to normal transmission.
- Please refer to this manual and use where there is no obstruction between the product and transmission equipment.
Be sure to select the switch located (see product structure) on the side of the unit prior
to use and apply the power.
- If you operate the switch during using, a large noise (pop noise) is generated and may damage the hearing when using
the earphone, and if connected to the audio device, it may cause problems with the audio unit and speaker system.

Wireless connection with smart devices is possible through a simple connection process,
so if music stored in smart devices can be played or streamed through AUX (external input)
terminals and sound devices that support external connection, by minimizing sound source
loss due to high sound quality codec application You can enjoy sound close to the original
sound.

How to set impedance adjustment switch
ⷈYou should adjust the impedance value of the equipment connected and can hear the best sound quality.ⷈ
The switches on the side are composed of two groups from #1 to #4.
The switches are divided into left and right channels, and the two groups must be adjusted in the same location.
If you adjusted each other dierently, the volume and quality of both the left and right can be printed dierently.
Correct Example Incorrect Example

If you do not know the input impedance of the connected device, rst turn all the switches
on the device to the OFF state and then try to listen. If there are lots of treble and lack of bass,
turn switch 1 only ON and then listen again.
But if it is the same though, increase to #2, #3 and #4 switches in the same way.
If the sounds stuy or too much bass,
> Since the number of switches in combination (the number of the ON position) is too large,
it is recommended to lower the number of combinations.
If there are lots of treble and lack of bass,
> Since the number of switches in combination (the number of the ON position) is too small,
it is recommended to increase the number of combinations.

How to set impedance adjustment switch
Do not operate the switch while wearing earphones or being on a connected device.
- A loud noise (POP noise) may be caused to damage the hearing or may cause a problem with the connected device and speaker system.
This unit is output at the same time in parallel at a 3.5mm stereo jack and a standard RCA Jack,
but if you connect all devices to the two outputs, it can be problematic on quality and performance.
- If possible, choose one of the two outputs, and use it after connecting the sound device.
You can expect a good characteristic to match the input impedance of the device that is connected to
Cave Audio Receiver (output impedance).
The value as illustrated above, is not an absolute value. It may dier depending on the device you wish to connect,
please use it after adjusting while listening.
As seen in page 7, the larger the sum of the combined switches, the lower the impedance.
Can be used to connect devices
same with 16Ω, 32Ω
1 2 3 4 ON
Example) Switch sum calculation
Can be used to connect devices such as home
audio with more than 10KΩ
1 2 3 4 ON
ⴘⴙ
Low impedance devices such as earphones (16Ω ~ 32Ω) = (# 3 to be On) or (#4 to be On)
High input impedance such as home audio (higher than 10KΩ) = ( only 3 time On) to be in place.
It is possible to use only one of switch no. 1, 2, 3 and 4 at the ON location or use all at on the ON location at the
same time, but switches can vary depending on the sound devices, so please select the most harmonious case.
