Technical details (1):
Amplifier:
Class D UCD™ Technology
Power ratings: TRUE SINE WAVE AVERAGE POWER
Copyright © by Elodis Subwoofer
Please notice: The following power ratings are somewhat different (conservative) to other published
power ratings but much more practice-oriented for subwoofer applications
(measurement shows „stiffness“ of power supply)
Vrms based calculating (P=Vrms2/R) by using sine steps
Procedure: sine steps 500 ms on – 500 ms stop (below 4 Ohms 250 ms on – 500 ms stop)
- and so on, 1/6 oct, 30-5000 Hz*),
additional measurement at 50 Hz for power ratings @ 50 Hz → continuous 5 s minimum,
pre-conditioned with several series of measurements at rated power
measured at 230 Volts/50 Hz, load → precision high power ohmic resistors,
environmental temperature 25°C:
*) 30-5000 Hz is the chosen bandwidth for power measurements.
Using music signals the amplifier is able to handle frequencies down to below
10 Hz masterfully also at very high power levels
2500 Watts/2.7 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
2300 Watts/3.15 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
2000 Watts/4 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
1500 Watts/5.4 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
1050 Watts/8 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
550 Watts/16 Ohms @ 50 Hz, THD = 0,5%, THD ≤ 0,5% 30-5000 Hz
Clipping-LED begins to flash slightly below rated power!
Minimum load should be around 3 Ohms for version 4to8 (see pages 18,19)
It is recommended to use rated power for maximum 1 second continuous
by using sine wave signals (see pages 18,19)

General:
No automatic switch-on/switch-off circuits are implemented to avoid unintended
switch-on/switch-off artefacts while listening music.
This active module can be switched in a standby mode by using the power switch on the
control panel (mounted on the front of the loudspeaker cabinet). Power consumption at
standby mode is very low → 0,5 Watts!
No further remote controls are provided.
The 2-pole main switch on the electronics module will power-off this unit completely
(when not in use for a longer time period). Power consumption at this mode is 0 Watt.
This active module is not equipped with measurement software or automatic measurement
software as standard. For best possible results all settings should be done and verified
by hand based on measurement data.
Nevertheless an advanced and convenient measurement software including an optimizer
is available on request.

ELODIS-SUB DSP-2500 4to8 Some useful information (1)
Amplifier driven at loads below 3 Ohms:
This amplifier is able to drive loads down to 1 Ω.
But notice the following recommendations:
At very low impedances the amplifier shuts down at the current limit of 50 Ampere
(Hiccup mode after limiting for 40ms)
High continuous sine wave power levels (not recommended, = no proper use) are able:
• to blow the unit main fuse (T10A, time lag, 250V)
• to blow power line fuses
• to blow the 2 internal rail fuses (F16A, quick-acting, 250V)
• to overheat the amplifier (amp shuts down at 85°C heatsink temperature)
Copyright © by Elodis Subwoofer
If high power levels at very low impedances (around 2 Ohms or less) are required continual, the version
ELODIS-SUB DSP-2500 2to4 could be a better option.
The only different to the „4to8“ version are the lower rail voltages (less heating).
Fans:
The two 80 mm fans are implemented to reduce heating at higher environmental
temperatures and at the same time high continuous power levels.
The fans will never start up at „accepted“ listening habits.
Please note: By calculating a crest factor of 12 dB (music program, dynamic compressed)
the average power will be around 200–300 Watts at rated power (clipping LED begins to flash).
The fans will start up at continuous sine wave power levels > 400 Watts (4 Ohms)
at 25°C environmental temperature.
The fans are decoupled from chassis.
Due to the optimized internal airflow super-silent (low speed) fans can be used.
19
ELODIS-SUB DSP-2500 4to8 Some useful information (2)
Do not test the ampifier by using continuous sine wave signals !
That is not what an audio amplifier is made for!
High power ratings should be considered as „welcome dynamic headroom“
When this amplifier will be measured take care that NO ONE of the amplifier outputs will be
grounded to the measurement equipment or elsewhere directly
due to the bridged topology of the amplifier !! Risk of damage !
Measurements and maintenance may be done exclusively by qualified personnel !!
Risk of electric shock and amplifier damage !!
Copyright © by Elodis Subwoofer
Do not drive the amplifier in permanent clipping mode
(permanent lighting up clipping-LED);
In further consequence → amplifier shuts down.
When the clipping-LED begins to flash → reduce input level !
To improve the sound performance up to the rated power no limiters are implemented
Power ratings are specified at 230 Volts/50 Hz
Increased or decreased voltages at the power supply line
will increase or decrease the specified power ratings
Do not use power strips! Use 1 wall power outlet for 1 ELODIS-SUB DSP-2500
High distorted power lines are able to decrease the performance of transformers
This unit must be earthed/grounded (Class 1)

Some recommendations regarding DSP settings
Your immediate action should be to find the best possible position for your loudspeaker(s)
Electronic „room corrections“ should be done with a small number of targeted and carefully
chosen adjustments based on 1/3 oct smoothed measurements.
Filter orders should not be higher than needed.

LP 80 Hz, Butterworth 5th, HP 80 Hz, Butterworth 5th

DSP - Example Application Subwoofer-Mainspeaker:
Small listening room with poor (but typical) room conditions
Crossover frequencies = LP 80 Hz, Butterworth 5th, HP 80 Hz, Butterworth 5th
Targeted usage of 5 EQ‘s for subwoofer and 10 EQ‘s for main-speaker
results in a (as was intended) slightly falling and well-balanced summarized frequency response.

ELODIS-SUB DSP-2500 4to8
This active module is designed for very high performance home audio
subwoofer/active-loudspeaker applications.
Copyright © by Elodis Subwoofer
The version 4to8 is optimized to supplies:
One subwoofer drive unit with a nominal impedance ≥ 4 Ω
Two parallel-connected subwoofer drive units
with nominal impedances ≥ 8 Ω
Several parallel-serial-connected drive units with a total
nominal impedance ≥ 4 Ω
To adapt a subwoofer best possible to the whole system
(room conditions, remaining audio equipment) is not an easy issue!
Many users fail!
Therefore:
Users should have the necessary basic skills and experiences
in measuring of audio equipment and room acoustics
as well as generally in electroacoustics!
Appropriately applied this active module will provides
an enormous powerful and accurate bass performance to any
above recommended subwoofer drive unit(s)
as well as generally amazing sound performance
to all connected loudspeakers due to the wide-ranging adaptabilities
and the high performance of the built-in DSP
All cables can be supplied as needed (standard length 1 m)
Different colors for the chassis parts are possible
All required installation parts (screws, …) supplied
