Page 6: Technical Features
TECHNICAL FEATURES IsoSyncECS Isolated Synchronous Error Correction System. Based upon an asynchronous buffer, voltage controlled crystal oscillators, and a 24 bit D/A converter – all under the precise control of an FPGA (Field Programmable Gate Array) running proprietary algorithms. BIT PERFECT AND Bit perfect conversion with total jitter output noise of less than 10 VIRTUALLY JITTER picoseconds RMS from any input –... - Page 7 6-LAYER CIRCUIT Multi-layer circuit boards provide extremely low impedance BOARDS ground and power distribution for remarkably low digital noise contamination. HIGH-PRECISION Extensive use of Lead (Pb)-free, low temperature coefficient, SURFACE MOUNT active and passive surface-mount components results in COMPONENTS significantly smaller loop areas, reduced circuit capacitance and inductance, and introduces less noise than conventional leaded components.
- Page 8 MAINTENANCE AND CARE All Jeff Rowland Design Group products are designed to provide a lifetime of enjoyment and listening pleasure. Chassis is sealed to prevent dust from entering the interior of the chassis and thus should never need interior cleaning during the lifetime of the product. All internal circuitry is maintenance-free such that no adjustments of any kind are necessary over the lifetime of the product.

Page 14: Remote Transmitter Battery Replacement
REMOTE TRANSMITTER BATTERY REPLACEMENT handheld remote transmitter is powered by 2 standard alkaline AA AERIS DAC batteries. When the remote transmission range decreases or no longer operates, the batteries need to be replaced. Using a standard flat blade screw driver, unfasten the holding screw located in the bottom end of the transmitter unit. -
Page 15: Using The Aeris Dac Volume Control
USING THE AERIS DAC VOLUME CONTROL is designed such that the volume control attenuates the signal up to 32 AERIS DAC dB below the point of LED flashing. When the right LED starts flashing, the AERIS DAC begins digital multiplication to increase the volume up to 20 dB above full scale. This would be for direct drive applications where the user would like to "rock out"... -
