INTRODUCTION
Intertek Milton Keynes were commissioned by AEA Technology, to carry out research on behalf of the DEFRA Sustainable Products and Materials team to produce data on the energy performance of analogue and digital radio receivers and a model of the projected changes in energy consumption resulting from the proposed switchover to digital in 2015. This report covers Phase 1 of this study, specifically the energy consumption measurements of analogue and digital radios. This is Issue 2 of the report and replaces Issue 1. Amendments and additional evaluation tables have been included in this issue. This report should be read in conjunction with Excel spreadsheet 66198 DAB Radios Results Table Issue 2.xls. This also replaces Issue 1 of the results table. Changes are highlighted in red. Testing was carried out at Intertek Milton Keynes during March 2010. The tests have been carried out in accordance with the test programme, and as such, the results are only applicable to the sample tested and the conditions of the test. Sample variability and changes in test conditions could influence some results, and the result(s) as stated may not be representative of the mean result if a number of different samples were tested under a variety of test conditions. Taken on its own, this report should not be used for regulatory purposes e.g. declaring conformance with directives.

Market Analysis
Market analysis was carried out to ensure that the products chosen for testing represented the market both in terms of brand coverage and specific models of radio. The following resources were used: 1.1 All the major manufacturers of DAB and audio equipment and the major electrical retailers were contacted directly to request specific information regarding their most popular radio models. The response to this direct contact was poor. 1.2 GfK sales data from 2003 to 2007 was made available to Intertek through MTP (Market Transformation Programme). Although more recent data has been published by GfK, the client decided not to purchase this. Using 2007 sales data, the market share of brands was analysed within DAB and non-portable audio categories. The following tables summarise the data by brand for portable DAB radios and non-portable audio (covering both analogue and DAB products).

1.3 More up to date data was provided by Intellect which detailed the five most popular models from four major manufacturers.

1.4 A thorough search of major online retailers and price comparison websites was also undertaken to identify the most common brands and models currently on the market. From these sources a list of currently available products was compiled (see Appendix II). All products were organised into brands and categories to enable short listing of products. The list of available products was compared with results that were available from previous testing and care was taken to avoid testing duplicate or similar models. We also ensured that there was good coverage of trade brands and non-trade brands as well as a range of price points.

Existing Data

Power consumption data for a range of older, as well as existing, radio products (over 100 models), belonging to other Intertek clients was made available to this project, after obtaining consent from these clients. These products were incorporated into the main database of available products and, from this list, 70 new models were selected for testing. The selection of models to test was based on a number of factors: good representation of the major DAB brands (as per GfK data). 72% of the market for DAB radios is held by three brands coverage of the majority of brands in the market. Data is available for 42 different brands. good representation of the various trade brands, given their high percentage share of the portable audio market good coverage of the different types of radio receiver, eg portable/tabletop, clock radios, Hi-Fi separates, CD players, iPod docks etc

Purchase of Samples

The samples selected for testing were purchased through normal consumer channels, either via the internet or from high street retailers. Two of the 70 models selected were either out of stock or discontinued at the time of purchase and, due to time constraints, could not be replaced.

Product Categories
The radios selected for testing were categorised into the following groups: Tabletop: Unit has integrated loudspeakers and mains powered only, Figures 1 and 2.
Figure 1 Tabletop (small)
Figure 2 Tabletop (large)
Tabletop/Portable: Unit has integrated loudspeakers and can be mains or battery powered. It is small/light enough to carry when battery powered and may have a carrying handle, recess or groove, Figure 3.
Figure 3 Tabletop/Portable

Page 11 of 25

Mini/Micro/Audio: The unit has separate loudspeakers and is likely to be a multifunction device probably incorporating a CD player or iPod docking mechanism, Figure 4. It is also mains powered only.
Figure 4 Mini/Micro System
Separates (including Home Cinema Amplifiers): The unit is not supplied with and will not produce sound until connected to a set of loudspeakers or as part of a larger system e.g. to an external amplifier with loudspeakers, Figure 5. In addition the home cinema amplifier is capable of driving a minimum of five loudspeakers designated front L/R, rear L/R, centre and sub or is supplied with six loudspeakers with the same designation, Figure 6. They are also mains powered only.

Figure 5 Separates

Figure 6 Home Cinema Amplifier (rear view)
In-car: This device will only work when connected to a cars DC battery system, Figure 7. It may convert DAB to FM or connect a DAB receiver directly to a previously installed FM receiver via the line input.

Power Consumption Measurements
Standby and off-mode measurements have been measured according to BS EN 62301: 2005. Where power saving features were available (e.g. dimming of displays, clock display on/off etc) measurements have been made at the minimum and maximum settings for standby mode and at the default setting for on-modes. Where two figures are entered in the results table for standby power, the first figure is the default, as delivered setting. For the on-mode measurements, a pink noise based simulated programme test signal was used as the input to the radios via a DAB or FM generator, the volume was then adjusted to achieve a sound pressure level of 70dBA measured in our standard 1 listening room. The measurement was recorded at 0.5 metre, 1 metre or 3 metres depending on the type of unit. For small radios and clock radios the distance used was 0.5 metres. For tabletop radios the sound level was measured at a distance of 1 metre. For mini Hi-Fi units and larger amplifiers the distance used was 3 metres. For systems that were not supplied with speakers, 6 ohm dummy load resistors (typical nominal speaker impedance) were used instead of speakers. The volume of the unit was adjusted to obtain a reading of 1 watt across one of the resistors, measured with a true RMS voltmeter. To ensure the units under test were correctly warmed up and electronically stable, each unit was turned on and allowed to settle for at least 30 minutes. The units were tuned to a signal and had their clocks set to ensure they were not hunting for signals. For standby measurements the samples were switched to standby after a minimum of 30 minutes in on-mode. The samples were then left for 15 minutes in standby before the power was tested and recorded. For on-mode measurements the same 30 minute warm up period was employed before the readings were recorded for FM and/or DAB and/or Internet Radio modes.

Throughout the testing procedure, the ambient temperature, relative humidity, airspeed and condition of the mains supply were monitored and controlled where necessary to ensure they complied with the requirements of BS EN 62301: 2005 and IEC 62087: 2008. Voltage: 230v 1% at 50Hz 1% Total Harmonic Distortion of voltage supply: < 0.2% Temperature: 23C 5 Relative Humidity: Between 10% and 80% Airspeed: < 0.5m/s
