The DSPPA DA4060 is a 4-channel Class-D power amplifier with 60W per channel on 70V or 100V lines and an independent volume knob for each channel. It suits buildings split into four small to mid-size zones, such as school floors, clinic wings or restaurant dining areas.
====
The DSPPA DA4060 splits your sound system into four independent zones from one chassis, with 60W per channel on a 70V or 100V line. Its strength is control rather than raw power: every zone has its own volume knob, so classrooms can sit at one level and the playground at another. It fits in 1U and accepts a 24V DC supply as well as mains AC.
DSPPA DA4060 specifications
The DA4060 is the entry 4-channel model in the DA series, followed by the DA4125 and DA4250 in the same chassis.
- 4 channels at 60W each.
- 70V or 100V output via a rear switch.
- Frequency response 80 Hz to 15 kHz; THD below 0.3%.
- Channel separation above 70 dB, so one zone does not bleed into the next.
- Power draw 347.6W on AC 220V, 57.5W at idle.
Four zones, four separate knobs
The front panel carries four knobs labelled CH1 to CH4. In a three-storey school, give each floor a channel and the outdoor yard the fourth. Each channel takes up to 60W of speakers, roughly ten 6W ceiling speakers.
Priority paging and battery operation
A balanced priority input and a 100V priority input mute the normal inputs when an announcement arrives and bring them back 2-3 seconds after it ends, so a message from the office cuts across all four zones. The unit also runs from 24V DC, which lets it sit on backup batteries, with rated output 3 dB lower on DC.
Protection and status at a glance
Five front LEDs, PRO, LIM, CLP, SIG and 70V, tell you what is happening. CLP means turn the level down; LIM on its own means the limiter has halved the output after 2-4 seconds at full power. Protection covers power-on, high temperature, DC on the output and short circuits, and the fan speed follows temperature.
Where the DA4060 fits in Saudi Arabia
- Schools: morning assembly and period bells spread across floors and the yard.
- Clinics and medical centres: patient calls in separate waiting areas.
- Restaurants and cafes: different background music levels for family halls and outdoor seating.
- Offices and branches: internal paging across four departments.
What you need with it
Inputs take line-level audio at 775 mVRMS through HT-3.81 Phoenix terminals, and the datasheet lists no mic input. Put a preamplifier or mixer such as the DSPPA MP9811P in front, then wire ceiling or wall speakers to each channel.
DA4060, DA4125 or DA2250?
The DA4125 keeps the chassis and four channels but raises output to 120W per channel, drawing 653W; choose it if any zone needs more than 60W. The DA2250 has two 250W channels instead, a better fit for two large zones than four small ones.
Frequently Asked Questions
How many ceiling speakers can the DSPPA DA4060 drive?
Each channel takes up to 60W of speakers, roughly ten 6W ceiling speakers per channel and about 40 across all four.
What is the difference between the DA4060 and DA4125?
Same 1U chassis, four channels and inputs. The DA4125 delivers 120W per channel and draws 653W; the DA4060 gives 60W per channel and draws 347.6W.
