Introduction:

Thank you for purchasing a ModWright Instruments product. This unit is designed to offer high
performance and exceptional reliability.

The ELYSE Tube DAC offers high bandwidth, low noise and distortion, and exceptional
musicality. We have designed this DAC to allow the reproduction of all digital recordings in a
way that is accurate, transparent and musical.

The ELYSE DAC has a direct-transformer coupled, all tube analog stage with zero coupling caps
in the signal path. This gives the analog signal the greatest fidelity and most natural and
resolving presentation.

The ELYSE DAC digital processing includes both data and clock buffering via a unique digital
algorithm. The result is vanishingly low jitter levels and the greatest detail for all formats, from
16/44.1 Redbook recordings, to 24/192 hi-rez streaming.

The ELYSE DAC was designed purposely with a tube rectified and solid-state regulated power
supply. Different types of rectifier tubes may be used in the ELYSE DAC, safely, and allow for
different tonality and presentation, to suit the taste of the listener.

Setup:

It is always recommended to remove all tubes before shipping the unit. Be sure that the ELYSE
DAC is NOT connected to AC power and that the power plug is disconnected from the unit and
wall outlet. Use supplied 5/64” hex driver to remove four lid screws in top panel and install (2)
6922 signal tubes in 9-pin ceramic tube sockets and the supplied 5AR4 rectifier tube in the
ceramic ‘octal’ tube socket. Align tube pins with socket and gently but firmly press the tubes
down into socket until seated.

After all tubes are installed, replace lid and secure with four screws. Only after this, should the
ELYSE DAC power cord be connected.

DO NOT POWER UNIT ON UNTIL LID IS ENTIRELY FASTENED. VERY HIGH
VOLTAGES ARE PRESENT INSIDE UNIT DURING OPERATION AND IT IS
CRITICAL THAT THE PREAMP ENCLOSURE NOT BE OPEN WHEN UNIT IS
POWERED ON. FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR
DEATH.
