Introduction
Let’s face it. You are the type who would happily crank up a full Ampeg SVT®
stack in your living room. Heck, who needs neighbors, anyway? And noise
violations are really just a badge of honor, right? For the rest of us, there
is the Ampeg MICRO-CL Stack, delivering 100 watts of Ampeg tone into any
situation. It’s perfect for those just getting into Ampeg tone or for the
seasoned bassist looking to practice in far-flung locations, like the master
bathroom. The MICRO-CL Stack features a tough, 2×10″ cab and tools like stereo
input and output for silent practice, effects loop, and direct out for
recording. It’s everything you want in a full-stack, micro-sized to fit
perfectly into your life.
Like all Ampeg products, the MICRO-CL Stack was designed by musicians and
built using only the best of components. Each stack is tested to confirm that
it meets our specifications, and we believe that this product is the absolute
best that it can be.
In order to get the most out of your MICRO-CL Stack, please fully read this
Owner’s Manual, as well as the Important Safety Instructions, included with
the product, before
playing.
Best of luck in all of your musical endeavors!
Sincerely,
The dedicated team at Ampeg

The Front Panel
1. 0 dB INPUT: The signal output from a passive instrument may be
connected to this 1/4″ Input by means of a shielded instrument cable.
2. –15 dB INPUT: The signal output from an active instrument may be
connected to this 1/4″ input by means of a shielded instrument cable.
3. MASTER: Use to control the output level of the instrument only.
It affects the Speaker Output [13] and Headphones Output [9]. Use it wisely
and turn it down when making connections, putting on headphones, or trying
something new.
4. TREBLE: Use to adjust the high-frequency level of the amplifier. This
provides up to 13 dB of boost, or 13 dB of cut, at 6 kHz. The high-frequency
output is flat at the center position.
5. MID: Use to adjust the midrange frequency level of the amplifier.
This provides up to 11 dB of boost, or 11 dB of cut, at 600 Hz. The midrange
frequency output is flat at the center position. Rotate the control
counterclockwise for a “contoured” sound (more distant, less midrange output)
or clockwise for a sound that really cuts through.
6. BASS: Use to adjust the low-frequency level of the amplifier. This
provides up to 11 dB of boost, or 11 dB of cut, at 50 Hz. The low-frequency
output is flat at the center position.
7. AUX LEVEL: Use to control the output level of the signal fed to the
Aux Input [8]. Use it wisely and turn it down when making connections, putting
on headphones, or trying something new.
8. AUX INPUT: The audio output from line-level sources such as a mobile
device or MP3 player can connect to this 1/8″ TRS stereo input. The incoming
audio is mixed with the preamp signals, so you can play along to a practice
track while listening with headphones. (The audio here appears in the cabinet
speakers until headphones are plugged in; then heard in the headphones only).
9. PHONES: Use this 1/8″ TRS stereo output to connect headphones. The
output here is a mix of the line-level signals reaching the amplifier, plus
any incoming audio from the Aux In jack [8].
Before putting on headphones, make sure the Master control [3] and Aux Level
[7] are turned down. This will reduce the chance of hearing damage due to loud
volumes.
Note: The speaker is muted when headphones are plugged in.
10. ON LED: This LED illuminates red when the power is on.
11. POWER SWITCH: Use this switch to turn the overall system power on or
off.
Press the top of the switch to turn on the power, and press the bottom of the
switch to turn it off.
The Rear Panel
12. AC POWER INPUT: The amplifier is equipped with a detachable power
cable that plugs into this IEC Mains socket on the back of the amplifier. The
AC power cord should only be plugged into a grounded power outlet that meets
all applicable electrical codes and is compatible with the voltage, power, and
frequency requirements stated on the rear panel of the amplifier.
Do not attempt to defeat the safety ground connection.
13. SPEAKER OUTPUT JACK: This 1/4″ TS Output jack supplies speaker-level
power to the Speaker Cabinet Input [17]. The rated power output is 100 Watts
into 8 Ω.
Rear Panel Connector Plate Use a (non-shielded) speaker cable with 1/4″ TS
ends to make the connections. Do not use (shielded) instrument cables as they
may overheat.
14. EFFECTS LOOP RETURN JACK: Use this 1/4″ TS unbalanced input to
return the processed, line-level output of an external effects processor (for
example).
The processor could be fed by signals from the Effects Loop Send [15].
15. EFFECTS LOOP SEND JACK: Use this 1/4″ TS unbalanced output to send a
line-level output to an external effects processor (for example). The output
here is affected by all controls, including the Master [3].
Use the Effects Loop Return jack [14] to feed the returned processed signals
back into the power amplifier.
16. UNBALANCED LINE OUT JACK: Typically, you would connect this Output
to the balanced input of an external mixer or a recorder. In this way, you do
not have to mic the speaker cabinet in order to add it to the main mix or to
record. This output is affected by the Master control [3].
This output can connect to external power amplifiers, or powered loudspeakers,
as long as they have their own input controls to adjust the volume level.
Rear Panel Connector Plate
17. 1/4″ TS INPUT JACK: Connect the speaker-level output [13] to this
speaker input jack using a (non-shielded) speaker cable.
Always use a (non-shielded) speaker cable—never use a (shielded) instrument
cable to connect speakers to an amplifier.
