SHIGARAKI SERIES
--------------------------------------------------------------------------------------------------------------------------------------------------
Model 4717 Shigaraki Amplifier including power supply $POA
The Sigaraki is 47 Labs' entry level amplifier featuring three inputs and one line output as well as a pair of solid speaker binding posts. The power supply is a standalone unit and volume is controlled via a simple slider on the main unit. The amplifier will drive most speaker systems with a nominal impedance 4 ohms or greater.
Specifications:
Output power 20 + 20 Watts into 8 ohms
Input Impedance 22k ohms
Line Output via fixed level RCA
Dimensions are 83mm x 198mm x 180mm for the amplifier and 145mm x 177mm x 125mm for the power supply
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Model 4716 Shigaraki Transport including ceramic power supply $POA
The Shigaraki transport features a machined alloy sheet chassis attached to a ceramic base for added rigidity. The unit is supplied with a magnetic puck to secure discs when in use and a clear acrylic dust cover to protect the mechanism when not in use. A fully functioning remote is supplied. Two digital outputs are supplied, one DC coupled and one AC coupled, both are via RCA socket. The power supply is fully ceramic encapsulated to eliminate RF.
Dimensions are 285mm x 85mm x 200mm for the transport and 76mm x 76mm x 141 for the power supply
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Model 4715 Shigaraki DAC including ceramic power supply $POA
The Shigaraki is designed specifically to complement the transport in both performance and looks. It is a two box unit encapsulated in ceramic which is electrically non-cunductive. Input sampling frequencies are 32, 41 and 48KHz selected automatically and output voltage is 2.1 volts. The unit features SPDIF unbalanced input and a pair of RCA outputs.
Dimensions are 76mm x 76mm x 80mm for the DAC and 76mm x 76mm x 141mm for the power supply.

REFERENCE SERIES
Model 4706 Gaincard with 4700 Power Supply Gaincard $POA
Power Supply $POA (50watt version)
The 4706 amplifier utilises only 9 components per channel (excluding attenuators) to achieve the worlds shortest signal path of a mere 32mm. The Negative Feedback Loop is only 9mm long. There are two versions available 25 watts per channel and 50 watts per channel.
The amplifier design is dual mono with both amps in a conjoined rigid aluminium chassis which acts a s the heatsink. Each amplifier features separate power on/off and a 12 step volume attenuator. Whilst the unit usually operates of one power supply module an optional 4706 'Dumpty' can be utilised for true dual mono operation.
Specifications:
Either 25 + 25 watts per channel into 8 ohms or 50 + 50 watts per channel into 8 ohms
Input Impedance 22k ohms unbalanced
Dimensions are 170mm x 40mm x 100mm for the amplifier and 130mm diameter x 195mm depth for the power supply making this system ideal where space requirements are at a premium.

Model 4712 Phonocube with 4700 Power Supply Phonocube $POA aud
Power Supply $POA (25 watt version)
The Phonocube is a true dual mono phono pre-amp designed for moving coil cartridges and features a true zero ohm input impedance. The unique equalising circuit features the advantages of both NF and CR filters. There both standard gain (75db) and high gain (90dB) versions available to suit your cartridges output voltage. This unit is a current amplification device featuring only 25 parts per channel and a signal path of a mere 44mm. Output impedance is the industry standard 47k ohms.
Dimensions for the Phonocube are 90mm x 100mm x 90mm. 4700 power supply dimensions quoted above.

Model 4713 Flatfish Transport with 4799 Power Supply Flatfish $POA
Power Supply $POA

The Flatfish chassis is machined from a solid billet of 16mm aluminium alloy to minimise vibrations from the motor mechanism. All drive and circuit components are rigidly attached to the chassis which results in a solid piece of engineering achieving very fast transient response. The unit features twin coaxial RCA outputs and is married to the 4799 power supply which delivers 120VA.
Dimensions: for the Flatfish are 170mm x 60mm x 245. 4799 power supply dimensions are identical to 4700.
