Technical details:
Weight without battery: 100 gr.
Measures: 9.3 x 4.7 x 2.2 cm
Supply voltage: 6 .. (9) .. 12 Volts DC
Mean current uptake: 7 mA
Maximal amplification (1 kHz): 4 / 17 dB (low/high gain)
Input impedance: 13 kOhm
Output impedance: < 1 Ohm
The unit runs from a single 9V battery and internally the supply voltage is used to create a pair of +4.5 and -4.5V power lines.
Alternatively external power supplies can be connected with supply voltages between 6V and 12V DC. The external supply voltage is internally splitted to create a pair of +3..+6V and -3..-6V power lines.
The total buffer capacity is 4000 uF to lower the effective battery impedance.
For amplification two single AD8610 opamps are used for maximal sonic performance.(No dual or quad-opamps!)
The 3.5 mm sockets are silver-plated.
Inside the signal path only metal-resistors and high-quality film-capacitors are used (polypropylene).
The enclosure is made entirely of aluminium.
Accessories:
- mini-mini interconnect (gold plated)
- screwdriver to open the amp
- 4 rubber feet
- user manual
