DA1008 AND DA2016 DISTRIBUTION AMPLIFIERS OPERATING AND MAINTENANCE MANUAL © Copyright 1997-2007, Audio Technologies Incorporated - Printed in USA Audio Technologies Inc. | 154 Cooper Road #902 | West Berlin, NJ 08091 | Voice 856-719-9900 | Fax 856-719-9903 | www. audio.com... - Page 2 DESCRIPTION The DA1008/2016 output stage is capable of driving 600 ohm loads directly to +26dBm with total freedom from crossover distortion, high inherent linearity, 100dB open loop gain and 50MHz gain bandwidth product make this an ideal device for highest quality audio distribution. The absence of Transient...
- Page 3 Active Balanced Outputs, +26dBrn DA1008-2, DA2016-2 An additional equal and out of phase output is provided by unity gain inverters A3, A5, A7 and A9 driven from the outputs of A2, 4, 6 and A8. Since the output summation across the load results in 6dB of additional level, the first stage gain is reduced proportionately to maintain the level set potentiometer near 12 o'clock for unity gain operation.

Page 4: Power Supply
POWER SUPPLY Dual power transformers are connected out of phase and thoroughly shielded to minimize radiated hum fields. Split primaries allow use on 115 or 230 VAC, 50/60 Hz. Primary bypass capacitors and a secondary Metal Oxide Varistor provide line transient protection. - Page 5 CAUTION: Active balanced output (DA1008-2, DA2016-2, ) has active drivers for both Hi and Lo output terminals. DO NOT GROUND either Hi or Lo terminals. To drive an unbalanced (one side grounded) load, connect it between Hi and GND terminals and let the Lo terminal float. Two separate 600 ohm unbalanced loads can be driven from each output without interaction by connecting one between Hi and GND and the other between Lo and GND.
