4175
Monitor Amplifier with Buffers |
| |
In the case
of the 4175, the board consists of two balanced IN &
OUT buffer amps totally independent of the Power Amplifier.
The PSU provides regulated outputs of +/-12v DC at a
nominal 750mA per rail and further provides the Power
Amp with unregulated DC as the TDA2030 has built in
regulation. The board comes fitted with a DIN41612 edge
connector (type B).
The 12/0/12 ac voltage should be fed via the DIN41612
Connector, (pin 28 ct, Pin 30 12v ac, Pin 32 12v ac)
The mains transformer can be mounted on the board, if
required.

Headphone Amplifier (4
x Line I/p, 8 x Line Drive)
| |
Although called
a Headphone System the board has a number of applications.
Four balanced Line Inputs are provided as well as eight
Line Drivers (unbalanced, although they could be balanced
by the addition of off-board transformers).
All amplifiers are independent allowing the user to
define his own application. Gain is provided (+26dB)
in the Line Drivers so a fader can be inserted between
Input amp and Output drive.
The outputs are low impedance but we advise against
the use of very low impedance headphones at high levels,
the 4075/4175 Monitor amplifier is better suited to
this kind of application
