TheLaChapell Audio 992EG is our flagship fully balanced pure class-A vacuum tube preamplifier and
instrument input amplifier. LaChapell Audio has gone to great lengths in making sure this preamp not
only deliver world class performance specifications but more importantly, deliver them with warmth
and character while using only the finest components.
TARGET APPLICATION
The 992EG can easily accommodate virtually any recording requirement. The 992 EG utilizes a Jensen
input transformer with dual ECC83 vacuum tubes per channel. With incredible noise performance and
>74dB of internal gain, the 992 closes the gap for those using ribbon mics, recording distant or faint
sound sources and/or passive hi-Z instruments.
BEFORE YOU GET STARTED
Stated below are a few areas that you must take the time to read before you power up and use the
992. You as the owner/user are responsible for completely understanding how to operate this device
safely and properly.
• UNPACKING: Inspect thoroughly! Although we take extreme care at final assembly and packing,
things can happen during transit. It is very important that you contact Digital Audio Labs if there is
anything broken or damaged upon receipt of package. . Included in every package should be:
(1) Model 992 preamplifier, (1) AC power cord, (1) packet of mounting screws, (1) owner's manual
w/registration card. It is a good idea for you to retain the packaging (box, foam caps and plastic
bag) in case there is a need to return the unit for service or repair at a later date.
• MOUNTING: Always allow for plenty of ventilation around the sides and top of preamp. Unlike
most 2-channel vacuum tube units, the 992 uses a total of eight tubes; this generates a lot of heat.
It is also important to NOT mount this unit above other sources that generate heat such as power
amplifiers or other tube gear. Always provide at least 1U (1 rack space) of clearance above
the 992. Mounting in travel racks in not recommended. Keep in mind that the vacuum tubes
are mounted in sockets and on rare occasions can shake lose if subjected to prolonged rough
handling. Finally, the 992 should never be mounted or placed in areas that would expose it to any
form of moisture.
