•
Amptastic Mini-1 amplifier
•
Amptastic power supply unit (optional)
•
IEC power lead (optional)
INTRODUCTION
The Amptastic Mini-1 amplifier provides audiophile sound quality, low
power consumption and beautiful design – all in a small, affordable
package. Drawing on the several years of research, this amplifier
represents the very best in Tripath digital audio design.
INSTALLATION
1
Carefully unpack and inspect all items, set aside and store safely all
packaging for future use.
2
Connect the IEC power lead to the Amptastic power supply unit and
plug in to the AC wall socket. Ensure LED is illuminated on power
supply, switch on AC wall socket if required.
3
Position the Mini-1 central to loudspeakers, away from sources of
moisture, excessive heat or cold. Do not use in or near water.
4
Connect loudspeaker cables to the Mini-1 speaker binding posts,
using either bare cable or 4mm banana plugs. Ensure correct
polarity matching, +ve and -ve to each speaker and post.
5
Connect RCA stereo interconnect to the R/L input on the Mini-1,
the other side to input source.
6
Ensure Mini-1 power switch is off. Connect DC plug on Amptastic
PSU to the DC input socket.
7
Set volume to low level and power on the Mini-1 unit via the power
button. The LED indicator on the Mini-1 should glow blue.

SPEAKER COMPATIBILITY
The Mini-1 is an efficient, low power audio amplifier. To get the best
experience it is recommended to partner with speakers of a high
sensitivity e.g. 85dB+ and 4g8ohm impedance.
The digital audio amplifier is internally bridged. It is therefore not possible
to operate in mono or tied output configuration. For more information
contact Support.
CONFIGURATION
It is possible to change the behaviour of the amplifier by changing
internal jumper link positions.
ACCESSING INTERNAL JUMPERS
1
Turn off and disconnect the Mini-1 from power supply unit.
2
Gently pull volume knob from the front panel.
