Overview
The A�C�E� (Analog Cabinet Emulator) is an active analog cabinet emulator
designed to offer guitarists a portable and convenient way to capture the
complex characteristics of a guitar speaker cabinet for a variety of recording
and live performance applications without the use of a microphone�
100% pure analog signal path from start to finish, the A�C�E� employs an ad-
vanced Multi-StageFiltering (MSF) network to generate stunningly realistic
speaker cabinet simulations that capture/bring to life all the warmth, punch
and character of a mic’d speaker cabinet to any performance without the
assistance of DSP (digital signal processing)�
A�C�E�’s on-board filtering is not your run of the mill EQ� Each control (Subs,
Highs and Presence) was carefully voiced to offer a musical range of tone
shaping versatility without becoming unrealistic, synthetic or fatiguing when
fine tuning your desired cabinet response�
Thank you for purchasing the Suhr Analog Cabinet Emulator™ (A.C.E)
Please take the time to read this manual to get the most out of the A.C.E.
The more you familiarize yourself with the features of this pedal, the more
you will enjoy its benets and maximize its potential.

Powering A.C.E.
DC Input*: A�C�E� accepts power from power supplies that are regulat-
ed 9 Vdc (center negative) See Technical Specifications on pg 14.
A�C�E� can also be powered internally from a 9V battery as described
below�
Installing/Replacing The Battery:
1�Unscrew the backplate of the pedal to access the battery compartment
with the battery snap located inside�
2�Plug in a 9V battery to the snap and re-screw the backplate�
NOTES:
The battery is connected when a cable is plugged into the FROM AMP
input or the LINE input and when there is no cable plugged into the DC
input.
ACE is a higher power device. A battery will last in the range of 3 hours.
Using the provided power supply is recommended for continued use.
TIP: For longer battery life, an Alkaline battery is recommended.
*WARNING: A.C.E. is NOT a Phantom Powdered device.

Inputs & Outputs
INPUTS
LINE: This input is for line level signals only.
NOTE: When using the line input, the INPUT level control is bypassed. Use
a signal cable for connections.
FROM AMP: This input is for Amplier Level signals. The output of an am-
plier can be plugged into this input while the amp is loaded by a suitable
load, such as a speaker cabinet or a Suhr Reactive Load. The load can
be connected to the TO SPEAKER input, which is connected in parallel to
the FROM AMP input. The load can also be connected in parallel with the
A.C.E. if the amplier has multiple available outputs.
TO SPEAKER: This input is a through connection from the FROM AMP
jack to allow the connection of a suitable load or speaker cabinet.
NOTE: When using the FROM AMP / TO SPEAKER jacks, use a speaker
cable for connections.
OUTPUTS
BALANCED: The balanced XLR output is a low impedance line level out-
put.
UNBALANCED: The unbalanced output is a low impedance line level out-
put. Use a mono 1/4” phone jack for this output.
Tip: The BALANCED output is the preferred output when driving long cable
lines. Balanced signals have the benet of rejecting injected noise from the
environment.

6
Controls
INPUT: This control functions only when using the From Amp input. It is
used to set the volume of your amp signal before it goes through the lter.
*This control can be set as desired as long as the Clip light does not turn
on. If it does, turn the Input knob counter clockwise to prevent the lter from
clipping.
SUB: This control reduces or increases the amount of low frequency bass
of the output
HIGHS: This control reduces or increases the amount of middle and high
frequencies of the output
PRESENCE: This control reduces or increases the amount of presence fre-
quencies of the output
LIFT GROUND (XLR): This switch lifts the ground on the XLR output when
ipped to the up position.
BYPASS/ACTIVE: When set to Bypass, the lter is bypassed and the out-
put is an unltered line level signal. When set to Active, the lter is engaged
as in normal operation.
PHASE (XLR): This switch ips the phase of the Balanced output (XLR)
when ipped to the up position.
