7 Features 7.1 System Features 7.1.1 Bluetooth Audio Subsystem [R63]. The system shall wirelessly pair to a Bluetooth-enabled device. [R64]. The system shall be up to date with the latest version of the Bluetooth protocol specification v2.1 and be compatible with the Enhanced Data Rate (EDR) specification (Data Rate: 3 Mbit/s). [R65]. The operating range of the system shall meet or exceed the requirement of a Bluetooth Class 2 device (Maximum permitted power: 2.5mW – 4dBm, Range: 30 feet). [R66].
[R80]. The system shall support an auto-off mode which causes the system to transition to off after 10 minutes of inactivity (i.e. no user input or no audio). The off mode shall comply with EuP 2013 power standards. [R81]. The auto-off mode shall capable of being disabled. [R82]. The auto-off mode disable control shall be accessible via the Deckard UI or over Wi-Fi. 7.1.4 LEDs [R83]. The system shall have one LED located on the top panel of the system.
8 State Summary 8.1 Power On/Off 8.2 Power Transitions [R106]. The unit is in power off mode when the AC power is disconnected. [R107]. The system shall transition from power off to standby mode (reaching an idle state ready for user input) within 1 second upon plugging the AC power in. [R108]. The unit should transition from off to operational mode instantly. If this is not possible the unit shall blink certain LEDs while transitioning from off to operational mode (to be defined in the UI spec). [R109].
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.
[R139]. The amplifier response shall be capable of being flat between 20Hz to 20kHz. In the audio path a DSP shall be used in order to correct for any linear acoustic distortion. [R140]. The system shall also have a limiter in order to optimize the max power max bandwidth parameters. 9.2.3 System Volume [R141]. The main system volume shall have 30 steps, representing gain of –40 dB to 0 dB. 9.3 Testability [R142]. PCB shall feature test points that allow for 100% nodal coverage. [R143].
