1. GENERAL DESCRIPTION
IP- 001AF is a network audio signal conversion processor. It can transform analog audio signals to digital
audio signals or transform digital audio signals to analog audio signals for long-distance transmission via
local area networks or wide area networks, featuring low signal transmission loss, good anti-jamming
capability and simple wiring.

3.NOTICES
 Input cables and output cables shall be placed separately; or otherwise resonance may occur.
 The processor shall be used in an environment with the temperature of 0~+40℃ and relative humidity
of no more than 90% (no dew formation).
 Before cleaning of the unit, it shall be disconnected from the power source. Then use a dry towel to
wipe it. For any difficult-to-remove smear, dip the towel with proper amount of neutral detergent for
cleaning. No gasoline, diluents, alcohol and the like chemicals shall be used for cleaning; or
otherwise deformation or discoloration may be caused.
 When the unit is connected to a DC power source, the DC power source or a power adapter of above
the unit’s rated current shall be used.

4.CONNECTION METHOD OF REMOVABLE TERMINAL PLUG
Notes
 For audio input and output, shielded lines shall be used.
 Avoid soldering cable conductor, as contact resistance may increase when the cable is tightened and
the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
 AWG 20～28 wire shall be used.
 Wire terminal treatment
 Wiring steps
Step 1: Hold down the button on the connection plug.
Step 2: Plug the wire with the terminal treated into the wire inlet hole, and release the button.
Step 3: Check the wire for proper location and against short circuit with adjacent wires, make sure it
will not be pulled off.

6.INSTALLATION
6.1 Wall mounting
By using additionally procured MB-15B connecting fittings, the unit may be wall-mounted.
Step 1: Use the M x8 screws provided along with the unit to fix the MB-15B connecting fittings on both
sides of the unit.
Step 2: Provide installation screws with proper sizes for wall-mounting based on the actual installation
environment to fix the unit onto the wall.

(to be provided by the user)
Step 1: Screw M x 8 (provided along with the unit) x 4
Note: it is not allowed to use other types of screws;
or otherwise damage may be caused to the internal
parts of the unit, resulting in failure of the unit.
6.2 Pa installation
When the unit is put on a table for use, the plastic pads can be fixed to the bottom of the unit with the
M x6 screws provided along.
Installation screws: M x 6 (provided along with the unit) x 4
Note: it is not allowed to use other types of screws; or otherwise
damage may be caused to the internal parts of the unit, resulting
in failure of the unit.

6.3 Power cor fastener installation
Use a power cord fastener to prevent fall of the power plug due to gravity of the adapter.
Step 1: Wind the adapter wire on the power cord fastener.
Step 2: Use the M x 6 screws provided along with the unit to fix the power cord on the side of the unit.
Step 2: Installation screws M x 6 (provided along with the unit) x 1
Note: it is not allowed to use other types of screws; or otherwise damage
may be caused to the internal parts of the unit, resulting in failure of the unit.
Step 1: Wind the adapter wire on the power cord fastener.
