1. Unpacking
KINKI STUDIO EX-P7 comes with：
- Preamplifier
- Remote Control
- Instruction Manual
- El cheapo Power Cord (Please use your own audiophile power cord for best sound)
Note:

2. Placement & Cold Start
KINKI STUDIO EX-P7 preamplifier, like all high-quality amplifiers, generates a certain amount
of heat and must be properly dissipated. To ensure good heat dissipation and cooling, do not
place temperature sensitive equipment on top of the amplifier.
3. Operational Voltage
The normal working voltage of the EX-P7 is AC 100-120V for AC110 option, and AC
200V~245V for AC230 option. If your normal operating voltage is outside the above range,
please consult us.
The EX-P7 is protected by a fuse located at the IEC inlet, rated at 2A slow blow fuse.

4. Connections
Connect the power cord to the IEC inlet of the amplifier and plug it into the power plug socket.
For safety reasons, a 3-wire grounding (earth) plug must be used, whenever possible.
In order to get the best sound from the amplifier, avoid using any multiple plugs socket or
extension cords.
The signal input connections are located at the center of the rear panel withindicationof
“LEFT IN” and “RIGHT IN” respectively.
You may use either RCA or XLR connection to source devices. The XLR Pinout is as follow:
- Pin 1 (Shield)
-Pin2(Hot)
- Pin 3 (Cold)
Note: The same set of inputs pair should be connected. For example, LEFT IN uses CH1, and
RIGHT IN must also use CH1.

5. Control
Power Up
The power inlet IEC of the EX-P7 is located at the rear panel. After the power is supplied to the
amplifier, it will be in Standby state.
Press the front panel left knob (SELECT) once. The display indicator light flashes signify a Start Up
sequence. The input signal source (CH1-3) and volume display appear once the amplifier is started
in Operational state.
Under normal working conditions, press and hold the left button (SELECT) onthefrontpanelfor
five seconds, then release it, the amplifier will go into Standby. The indicator in the lower right
corner lights up.
Note: Whenever you turn it on, the volume will be automatically set to 10 position to avoid
damage to the speaker caused by excessive volume.
Volume adjustment
Rotate the front panel right knob (VOLUME) to adjust the volume, to reduce volume, turn left; to
increase volume, turn right. Each step is 0.5db, there are total 256 steps.

5. Control – Con’t
Mute
Under normal working conditions, press the right knob (VOLUME) once, the display will show MUTE,
the input source number and volume display will disappear, the amplifier will be in the Mute state.
To un-mute, press the right knob again to return the amplifier to the Operational state.
Input Source Selection
By turning the left knob（SELECT）to switch between Input CH1, CH2, CH3.

6. Optimization
Placement platform
The EX-P7 has extraordinary dynamic capabilities and sound transparency. To fully unleash its
performance, it must be placed on a rigid platform or proper HiFi rack. Please avoid the use of
any soft materials such as carpets underneath the amplifier.
Warm Up
When the preamplifier has not been used for a while, it will take 20 to 45 minutes to "warm-up".
In order to achieve the best operating temperature, the circuit must be warmed up to
approximately 40 degrees Celsius. It is advisable to keep the supply power on all the time for
optimal performance.
Note: The EX-P7 amplifier takes about 300 hours to burn in. Please don't worry, the sound will
and can only be improved as it burns in.

8. Product Care
The EX-P7 usually requires no maintenance and requires only occasional cleaning of the physical
surface.
The power must be turned off and removed before cleaning the amplifier. Clean the surface of
the amplifier with a soft, slightly damp cloth. Wipe gently with a soft cloth dampened with water
or a mild detergent solution. Please avoid the use of harsh detergents (i.e. product containing
sodium carbonate).
