ing any cable , or when cleaning any component. To completely di connect thi apparatu
from the AC main , di connect the power upply cord plug from the AC receptacle.
2. NEVER u e flammable or combu tible chemical for cleaning audio component .
3. NEVER wet the in ide of thi component with any liquid. If a liquid ub tance doe enter
your unit, immediately di connect it from the AC main and take it to your Aeron Dealer for
in pection.
4. NEVER pill or pour liquid directly onto thi component.

out of torage from an unheated environment, let the unit acclimate to room temperature be-
fore making any connection and applying power to the unit.
8. LW YS keep electrical equipment out of reach of children. Do not handle the tube when
hot, or wet them. Only touch the tube only when they are cold and the unit i unplugged
from it ource of AC Power.
9. LW YS unplug en itive electronic equipment uch a thi unit during lighting torm .

Installation
In your System
To in ure normal component life and afe operation thi unit mu t be oper-
ated only in a horizontal (upright) po ition. Adequate airflow and proper
cooling thereby can occur only if there i no re triction below, behind and
above the unit.
The four pecial non-marring ela tomer feet provide adequate pacing only
from a mooth, hard urface. Never operate the unit while it i itting on a
urface uch a a rug or carpet.
If the unit i to be operated in an enclo ed equipment cabinet, an exhau t
fan i de irable o a not to operate the LP-X1 in overheated ambient air.
The “ambient” operating temperature hould never exceed 120oF or 49oC.
Improper in tallation will cau e premature tube failure and will affect your
warranty, a well a the ervice life of the unit.

Connections
C Power Connection
It i e ential that the phono amplifier be connected to wall AC power recepta-
cle, or a imilar heavy-duty ource. If it i connected to convenience receptacle
on preamplifier , etc., the full onic capabilitie of both the LP-X1 and the
preamplifier will be compromi ed.
For the very be t onic performance, the LP-X1 hould be connected to it own
AC power circuit branch, protected by a over 5 amp breaker. The other audio
equipment hould be connected to a different power circuit and breaker. Avoid
the u e of exten ion cord . If they mu t be u ed on a temporary ba i , u e
High quality power cord .
The LP-X1 utilize a compatible grounding y tem that generally doe not re-
quire a “ground lifter” adapter plug on the AC power cord to minimize hum. The
power cord upplied with the LP-X1 ha a tandard three-prong grounding plug
to provide maximum afety when it i connected to a grounded wall receptacle.
If there i any que tion regarding the afety of grounding procedure , be certain
to eek competent help with the in tallation.
Rear Panel Connections
All two et of Single-Ended input, one et of mm phono input and one et of mc
phono input are clearly marked to indicate u e.
One et of Single-Ended output and connect to integrated amplifier or pre-
amplifier line-level input (e.g.: AUX, Line 1)

Operation
Power-up Procedure
Make ure you have read and complied with the In tallation and Connection in-
truction prior to attempting operation.
Power-On & Shut Down
Pre the “Power” button to turn unit ON / OFF
General Notes about Usage
Turn off the LP-X1 wait at lea t five minute before turning it on again. Thi brief
cool down period will reduce tre on the output tube and potential
damage to them.
Aeron doe not recommend leaving your LP-X1 on 24 hour a day a i the cu -
tom of ome li tener to achieve maximum onic performance on demand. While
thi i often recommended for olid- tate equipment, Aeron doe not
recommend thi procedure for MM/MC Audiophile Grade Tube Phono
Preamplifier.

Operation
Front Panel Control Functions
Phono — MM/MC
Select the ource “MM” or “MC”
For MM phono cartridge, appeared MM capacitance needed to be elect.
Plea e check your MM cartridge pecification, normal MM capacitance i 47pF.
For MC phono cartridge, appeared MC Impedance need to be elect.
Plea e check your MC cartridge pecification, normal MC impedance i
100ohm .
Level
Output level can be adju t on front Panel.
Subsonic
Sub onic filter can reduce unwanted ub onic ignal in order to re erve the am-
plifier power. LP-X1 provide two level of ub onic filter 20Hz & 40 Hz.
For normal etting, we recommend u ing 20Hz ub onic filter.
