9 Technical Requirements
9.1 Power
[R125]. The main shall conform to local Energy Efficiency laws and regulations in the country of
destination.
[R126]. For the European Union this requires compliance with “DIRECTIVE 2005/32/EC on Energy Using
Products” (as amended) as implemented by “COMMISSION REGULATION (EC) No 1275/2008” and /
or “COMMISSION REGULATION (EC) No 278 2009”. When in Standby State, the power amplifier,
DSP are turned off and the MCU is in low power consumption mode. In standby state, the EuP
requirement for power consumption is 0.5W for 2013. The 2013 standard is mandatory.
[R127]. Countries outside the European Union also have requirements. Examples include, but are not
limited to, Australia, Canada, Korea, Switzerland, USA
[R128]. The power supply shall be a wall-wart type universal switching power supply in order to
accommodate world wide use.
[R129]. The captured 1.5 meter long 2-conductor power output cable shall terminate in a barrel type
connector with the power input jack on the rear of the Pan unit (see section 6.3.1.1)
[R130]. The power supply shall have the following characteristics:
Input
100-240 V AC 50/60 Hz
Output
12V DC 2A
[R131]. It is highly desired for the AC power cord to be as thin and flexible and also to have a small as
possible connector. This way the user can elegantly route the power cord to their desire. If possible,
the power cord should have 2 conductors and no ground as long as it passes all regulatory
requirements.
[R132]. The EMEA power supply shall have interchangeable plugs for EU and UK.
[R133]. The following images are descriptions for each power supply type. They are grouped by SKU.

9.2 DSP
9.2.1 Audio Routing
[R134]. The unit shall support playback of any one audio source at any time. The sources are:
[R135]. Bluetooth Subsystem
[R136]. Wi-Fi Subsystems (For Caprica Module Only)
[R137]. System Sounds
9.2.2 Filters and Limiter / Compressor
[R138]. The signal processing block of the system shall be capable of processing a minimum of 5 biquads
per channel. Provisions shall be made for Phorus to access the DSP to modify the filter coefficients
for acoustic tuning.
