Important Precautions
To reduce the risk of electrical shock or f ire, do not expose this unit rain or
moisture.
Make sure that the AC Mains voltage is correct and matches the voltage painted
on the rear panel of the amplifier (110 V or 220V)
Do not spill water or other liquids into or on to your unit.
Do not attempt to operate this unit if the power cord has been frayed or broken.
Do not attempt to remove or break off the ground prong from the electrical cord.
This prong is used to reduce the risk of electrical shock and f re in case of an
internal short.
Disconnect main power before making any type of connection.
Do not remove the cover under any conditions. There are no user serviceable
parts inside.
Never plug this unit in to a dimmer pack.
Always be sure to mount this unit in an area that will allow proper ventilation. Allow
about 6” (15cm) between this device and a wall.
Do not attempt to operate this unit, if it becomes damaged.
This unit is intended for indoor use only, use of this product outdoors voids all
warranties.
During long periods of non-use, disconnect the unit’s main power.

During long periods of non-use, disconnect the unit’s main power.
Always mount this unit in a safe and stable manner.
Power cords should be routed so they are not likely to be walked on, pinched by
items placed upon or against them.
Cleaning -The outside of the unit should be wipe down with a soft cloth and mild
cleaner when needed.
Heat -The amplifier should be situated away from heat sources such as radiators,
heat registers, stoves, or other appliances (including amplifiers) that produce heat.
The fixture should be serviced by qualified service personnel when:
A. The power-supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the unit.
C. The appliance has been exposed to rain or water.
D. The fixture does not appear to operate normally or exhibits a marked change in
performance.

Introduction
Congratulations and thank you for purchasing TD14000 amplifier. This amplifier is a
representation of UNiKA’s continuing commitment to produce the best and highest quality
audio products at an affordable price. These amplifiers are designed to provide a big
impact in sound reproduction. Please read and understand this manual completely
before attempting to operate your new amplifier. This booklet contains important
information concerning the proper and safe operation of your new amplifier.
Unpacking: Every TD14000 amplifier has been thoroughly tested and has
been shipped in perfect operating condition. Carefully check the shipping carton
for damage that may have occurred during shipping. If the carton appears to be
damaged, carefully inspect your unit for any damage and be sure all accessories
necessary to operate the system have arrived intact. In the event damage has
been found or parts are missing, please contact your dealer for further
instructions.
Installation: This amplifier is designed to mount into a standard 19”rack. The
front panel provides four holes used to screw the unit into a rack. The unit also
provides a way to rear mount the unit into a rack for added security. Rear mounting
the unit is especially recommended if the unit is to mounted into a mobile rack.

1. Carry/protection handle - Both handles can be used to carry the amplifier, they also
act as protection for the front panel.
2. Input level attenuators - These controls are used to alter the signal level entering the
amplifier. They are calibrated in dB to help set up active loudspeaker systems or cut
down unwanted noise from the input signal.
3. Over temperature protect indicator - This indicator lights if the amplifier tries to
operate above its maximum operating temperature (90oC). The indicator first comes
on as a warning to either turn down the input level or check the cooling arrangements
after which point the amplifier will mute the input signal. When the cooling fans have
returned the output heat sinks to the normal operating temperature the input signal is
unmuted.
4. VHF protect indicator - This indicator lights when constant signals, above 12 kHz at
full power, are present at the output terminals. When this happens the input signal is
muted and the process cycles until the VHF signal is no longer present.
5. Clip/limit indicator - This indicator tells when the amplifier output is clipping or
limiting. The two different states can be told apart:
When the clip limiter is engaged it flickers briefly.
When the clip limiter is not engaged it lights for a longer period.
6. Fan grill filter - A foam filter is located behind the front panel to prevent dust entering
the amplifier.
7. Power switch - This is used to start the amplifier.

Level selections vary by model within the TD14000 amplifier.
Mode - Select VPL mode to either Hard or Soft operation. For channels driving sub-woofers
and low-frequency drivers, it is recommended to use the Hard setting for optimal operation.
For mid-and-high-frequency drivers, always select Soft.

Operation and Performance
Signal flow blocks
All TD14000 amplifiers have the same signal flow, and the same feature sets. The only
internal differences are in the maximum output current per channel and VPL settings.
The input stage of all Td14000 amplifiers has a high sensitivity to provide ample system
headroom. This in effect means that the input stage is almost impossible to clip.
Overall amplifier input gain is adjusted using the input stage DIP-switches. Please note
that the gain setting is global, affecting all channels. Following the input stage, the
dedicated level control on each channel allows signal attenuation from 0 dB to minus.
The Current Peak Limiter(CPL)section dynamically limits the input signal based on three
parameters: sensed current level, feedback from the output stage, and sensed voltage
clip from the VPL (and output amplifier voltage clip if “Soft Clip” is activated). This
ensures that power output is maintained within the design limits of the amplifier.
The adjustable Voltage Peak Limiter(VPL) sets the maximum output voltage and
therefore also the maximum output power. Eight different voltage stages are available
using the DIP-switches on the rear panel.
The sophisticated output section monitors faults and generates appropriate warnings,
which are displayed on the amplifier front panel These alerts allow the operator to adjust
system settings and thereby avoid problems. In the rare event that condition are
extraordinarily severe, the amplifier will shut down until the fault or problem setting ha
been rectified or adjusted. These sensing circuits level information, via a side chain, to
the limiters. Sensing circuit also transmit local amplifier module temperature and power
supply temperature to the appropriate protection mechanisms. Read the Protection,
Faults and Warnings section for further details.
