GENERAL
DFseries with DSP (DF1400DSP, DF2000DSP, DF3200DSP) are modern
amplifiers for professional entertainers, who require maximum performance and sound
quality on a limited budget. Amplifiers are designed for application in
PA systems with high requirements for precise tuning of the parameters, but without the
need for operative change.
Built-in DSP accurately handles the audio signal due to its functions of equalization,
filtering, delay and limiter. Processor has 2 inputs and 2 outputs and provides free signal
routing from any input to any output.
DSP enables users to choose between eight factory preset settings. Setting
presets (operation modes) is performed by DIP switch. Any of presets can be modified
using a computer connected via USB interface (software – SigmaStudio by Analog
Devices, Inc.).
ATTENTION! The DF1400DSP, DF2000DSP and DF3200DSP amplifiers have the
same design and functional features and differ only in the schematics elements, output
power and weight. Unless specified otherwise, the word «amplifier» hereinafter applies to
any of the above models..
To ensure the most advantageous and faultless operation of the amplifier, please,
read this Manual before use.
UNPACKING
The manufacturer’s quality control system provides for careful examination of each
product before it leaves the factory to ensure its flawless appearance. After unpacking,
please, check the unit for any physical damage. In case of damage, please, contact your
local dealer. Keep the shipping carton and all packing material, as you may require them
for reshipment of the unit.

DESIGN FEATURES
Physical Design
The amplifier is enclosed in a metal (steel) case of 88 mm (2U) height. The amplifier
is designed to be standard rack-mounted (RACK 19").
Power Supply Unit
Both channel of the amplifier share the same pulse power supply unit.
Power Factor Correction (in DF2000 DSP only)
The amplifier has power supply with Power Factor Correction, which significantly
reduces load to the mains and also reduces noise and distortion in the mains. What is
more important, the amplifier output power is no longer rigorously dependent on the mains
voltage. The amplifier provides full power at the mains voltage from 160V to 250V (with ~ ~
no need to use of external AC voltage stabilizer).
Cooling System
The amplifier features a forced cooling system which is common for both channels.
The amplifier and the power supply unit are cooled with a single fan blowing front to rear.
The cooling system provides for a double-step intensity-cooling rate switching. At a normal
temperature, the fan runs at a low speed, thus generating the least noise possible. When
the amplifier is set to deliver a high output power or when the ambient temperature is
higher than normal, the cooling system may switch the fan to the other (higher) cooling
rate.
Output Stage
The output stage of this digital power amplifier is designed according to Class D
technology to deliver high efficiency and least heat. The high switching rate ensures the
high sound quality comparable with the best analogue amplifiers.
Balanced Inputs
The use of balanced inputs provides for an essential reduction of the environment-
induced hum and noise interference with long input connecting cables.
Line Outputs
The line outputs have a post-DSP signal. The signal parameters are determined by
the selected preset setting. You can change the signal parameters using the USB
interface.
DSP
Built-in DSP accurately handles the audio signal due to its functions of equalization,
filtering, delay and limiter. Processor has 2 inputs and 4 outputs and provides free signal
routing from any input to any output.
DSP enables users to choose between eight factory preset settings. Preset
parameters are listed on the insert in the Owner’s Manual.
Any of presets can be modified, using a computer connected via USB interface
(software – SigmaStudio by Analog Devices, Inc.).
The installation package of the SigmaStudio ver.3.10 software (32-bit and 64-bit
program versions available) and user manual can be downloaded from the site
parkaudio.ua (Download section on the pages of the corresponding amplifiers).

DSP PRESET Switch
The amplifier modes (DSP presets) can be switched by the DIP switch, located on
the rear panel.
Input Level Attenuators
These allow setting the amplifier to the required sensitivity (each channel
individually) which is very helpful when several amplifiers are used to drive different types
of loudspeakers or are used within multi-speaker sound reinforcement systems. The
attenuators are located on the front panel.
Detachable Power Cord
This feature is provided for convenience of transportation and rack mounting.

FUNCTIONAL FEATURES
Overload and Short-Circuit Protection
Individual per each channel. This protective system becomes active in case of short-
circuited output or overload caused by reduced load impedance. It disables the output
signal of the respective channel for 0.5 second and then the amplifier gradually resumes
its delivery.
DC Output Protection
The amplifier’s schematics precludes transit of any clicks or noise during the power-
on/off transition process. The power source unit is responsible for preventing any DC
damage to loudspeakers. In the event of output DC voltage or any powerful LF
fluctuations, the power source unit goes off and all indicators, including the POWER LED,
go off too.
The amplifier can be restarted in 2 or 3 minutes by de-energizing and re-energizing
the amplifier with the POWER switch. If the DC is an occasional problem (which is unlikely)
the amplifier goes on and resumes its normal functioning. If, otherwise, the DC output
problem persists through the fault of the amplifier, then upon switching, the amplifier goes
on, the POWER amplifier goes on but in a short while the DC output protection system
disables the power supply source.
Thermal Protection
Independent for each channel. In this case upon reaching 85°C, the independent
protection system disables the respective channel of the amplifier. The CLIP LED goes on
and the SIGNAL LED of the affected channel goes off.
As soon as the amplifier cools down, the affected channels gradually regain their
amplification level up to the set value.
Soft Signal Start
During the power-on process, this feature ensures smooth gain from zero to the
maximum level to provide for a smooth rise of the sound level emitted from the loud-
speakers.

CABLE REQUIREMENTS
Input Cables
Make sure to use only shielded cables whether balanced or unbalanced. Shielding,
when properly grounded, protects a signal against external electrical interference.
As a rule, unbalanced lines over 3 meters long are not acceptable. Greater distances
require a balanced cable. Avoid placing input cables close to power cords or power
transformers.
Output Cables
The amplifier is capable of delivering high level output current; therefore, the wire
gauge used for speaker cables is particularly important. Inadequate wire gauge adds
significant resistance to the speaker’s own impedance, reducing the power, which is
actually delivered to the speaker. It will also result in a decreased damping factor and
possible fire hazard.
Since the power, applied to the loudspeaker, is of primary concern in system design,
we have included the table below to allow you determine the appropriate wire gauge for
your application.
Power Loss in a 10-meter Cable
The table shows the percentage of the power loss in a 10-meter copper multiple-core
cable. This table reflects the power loss as a percentage of the output power of the
amplifier applied to the load. Use this table to determine the power loss to the load at other
cable lengths. For example, if you plan to deliver 100 Watts to 8-Ohms load through 20-m
2
cable of 0.75-mm gauge, the power loss in the cable would be 5.8% x 2=11.6% of 100W
or 11.6W lost in the cable.

RACK-MOUNTING REQUIREMENTS
The amplifier is designed to fit a standard 19” rack. While mounting, make sure to
provide unhindered air access to the front and rear sides of the rack. Fan direction is from
front to back. It is not necessary to leave empty space above or below the amplifier.
For stationary use, it will be enough to fix securely only the front panel of the amplifier
to the rack. However, never attempt to transport the unit unless its rear end is properly
supported and/or securely fixed, as it may be fraught with danger of damage.
AC POWER REQUIREMENTS
The amplifier is supplied with a three-conductor grounded AC power cord, and
should be plugged into a standard 3-wire grounded electrical outlet, which supplies
230VAC 50/60Hz.
In the event of line voltage sag, the amplifier without PFC will continue to operate
normally, albeit with less power. The mains lower voltage limit for the amplifier to retain its
operability is ~160V.
The amplifier with PFC operates at the mains voltage range from ~160V to ~250V,
giving the full rated output power.
The amplifier is connected to the mains via cable, supplied with the amplifier. When
connecting to mains, make sure that no other devices with high power consumption are
connected to it, as the normal operation of several such devices may be impossible.
The actual AC current consumption depends on the audio signal level and the load
impedance. For system design purposes it must be noted, that for typical audio program
material the amplifiers, driving all channels at nominal impedance, just peaking at the
clipping level, have the following average power consumption:
– 2.4 A* for amplifier DF1400 DSP at 4 Ohm load;
– 1.2 A* for amplifier DF1400 DSP at 8 Ohm load;
– 3.4 A* for amplifier DF2000 DSP at 4 Ohm load;
– 1.7A* for amplifier DF2000 DSP at 8 Ohm load;
– 5.5A* for amplifier DF3200DSP at 4 Ohm load;
– 2.8A* for amplifier DF3200DSP at 8 Ohm load.
Note.
* At the mains voltage 230V AC. For the amplifiers DF2000DSP (with PFC) at low mains voltage
the current consumption increases.
In order to reduce the AC hum, please, plug all sound equipment, interconnected with
signal cables, into the same power mains outlet.
11

AMPLIFIER OPERATION MODES
The amplifier can operate in two or one-channel modes (respectively: each channel
independently, the two channels in a bridge mode). The amplifier has two input channels.
Signals routing for four channels is performed by the DSP engine.
DSP settings control, presets storing and the creation of the original signal
processing template is performed by personal computer with SigmaStudio editor,
installed to it.
Setting the high-pass filter and crossover filter parameters, EQ settings, desired
signal delay, as well as a number of other parameters can be performed by the DSP
engine, as described in SigmaStudio User Manual .
For the consumer’s convenience the amplifier has 8 presets, which provides a
number of the most frequently used switch configurations and settings. DSP presets
settings and block diagrams of the connections to the amplifier are in the Owner’s Manual.
Switching the amplifier DSP presets is performed by the DIP switch, located on the rear
panel of the amplifier.
