Whether you want to view it as a high-end preamplifier with a built in magnificent DAC or a Converter with 4 extra analog inputs is up to you. It starts with 4 digital inputs spanning the AES/EBU, SPDIF, Toslink and ST formats. February 2002 brought us a new 24 bit 96KHz digital to analog converter board designed by Fred Forssell. We merged this new DAC with an improved tube stage and added two analog balanced AND two unbalanced inputs. Outboard power supply too. Three sets of outputs and a processor loop are also all switchable from the front panel AND (big news...) REMOTE CONTROL!!!!!!!!!!!!! MANLEY's first piece with remote control is a total "over-killer" The *entire* faceplate can also be operated by the remote, especially and finally including the volume control.
The WAVE is a unique product combining a killer 24/96 Digital to Analog Converter with a full-featured audiophile analog vacuum tube preamplifier. It is one of the very few products equally at home as the heart of a professional Mastering studio facility as it is as the centerpiece of an audiophile home system. The combination of features and functions came about from analyzing existing systems and finding them functional but lacking in elegance in signal flow, operational convenience, and synergy. We set out to build something we wanted in our own living rooms, something that could be upgraded as new standards evolved, and something that could be flexible to work with mixed balanced, unbalanced, analog, and digital connections. A swiss army knife of sorts...
The digital board used in the first generation units, (the "First Waves" as it were) was designed around the ULTRAANALOG 20-bit DACs, the AES-21 jitter reduction input module, and the Pacific Microsonics HDCD decoder. This chipset ruled the 1990's audiophile digital world. In early 2002 we commissioned an excellent 24 bit, 96KHz DAC board design from talented designer Fred Forssell for the second generation units, in current production as of this writing. The WAVE accepts four digital inputs in the following formats: AES, SPDIF, TOSLINK, and ST Glass Fiber. The four analog inputs come as stock 2 RCA + 2 XLR. Other configurations can be custom-ordered as desired. To provide extra flexibility in system integration, we have included an Insert Loop (term borrowed from the recording studio world) perhaps more commonly referred to as a Tape Loop or Processor Loop in Audiophile-land. Three outputs are provided: outputs 2 and 3 can be switched; output 1 is always on.

Burr-Brown PCM1704 D-A converters operating at 96 KHz at all times
All inputs below 96 KHz are upsampled to 96 KHz before conversion
The upsampled output is clocked out via a Low Phase Noise/Low Jitter
precision crystal oscillator to eliminate any interface jitter or timing
problems with the incoming datastream
Multiple power supplies are used, with additional regulation and
filtering located at all critical components
Differential Passive LC filtering is used on the voltage output of the
High Speed JFET Current to Voltage Conversion with differential output is
used to drive the Passive LC Filter
It will wash your car, clean your windows, make coffee and sound
good all at the same time...

REMOTE CONTROL RANGE MEASUREMENTS
If the remote is closer than 9 feet, the maximum angle response is around 60 to 75 degrees which is the counter sink angle of the receiver's hole in the front panel. Measurements done with new set of batteries.
- Distance of 9-10 ft, the maximum angle is 65-75 degrees.
- Distance of 12 ft, the maximum angle is 60 degrees.
- Distance of 13 ft, the maximum angle is 45-55 degrees.
- Distance of 16 ft, the maximum angle is 45 degrees.
- Distance of 20 ft, the maximum angle is 25-35 degrees.
- Distance of 25-27 ft, the maximum angle is 0-15 degrees. This is the maximum distance-angle the remote will do.
