Mambo AMP 10 User manual

This information is for guidance and applies to the standard 500 watt guitar combo.
Specification
•500 Watt rms continuous power rating, 250 Watt rms with the internal speaker, plus an
additional 250 watt rms when used with an external 8 Ohm loudspeaker, an r.m.s. limiter
prevents power amplifier overdrive while allowing loud transients to e faithfully reproduced.
•24 it digital rever , with depth and delay-time controls
•hand-made irch ply ca inet
•two guitar input jacks ,
•line level input (3.5mm stereo jack) for MP3 / CD etc.
•headphone output (3.5mm stereo jack)
•European (230 V) or US (115V) mains voltage (specify when ordering)
Size and weight (approx.)
•12" - 12.1 kg, 36 y 36 y 30 cm
•10" - 8.1 kg, 31 y 31 y 25 cm
•8" - 7.3 kg, 27 y 27 y 23 cm

Inputs and controls
•two guitar input jacks, normal (A) and low gain (B)
use the normal input for most guitars, use the low gain input for very high output guitars
or other signal sources. Both inputs can e used at the same time, in which case they
automatically switch to normal gain. Useful if you use two guitars on stage, or for
teaching etc.
•gain
adjust to taste, at higher gains the harmonic setting will have more effect, in a similar
way to a valve preamp. As a starting point set to 12 O'clock. On the harmonic setting it is
possible to overdrive the preamp slightly with high gain settings when playing loud, This is deliberate, but if you
want a cleaner sound, turn the gain down, or use the clean setting.
•tre le
•middle
•ass
•power on LED
•headphone out ; stereo 3.5mm jack
when using headphones, turn the master volume down to zero to mute the loudspeaker
•line in ; stereo 3.5mm jack, for mp3 /cd etc
•
•right / normal / deep ; 3 way switch
the normal setting is the classic mam o amp sound
deep setting has slightly more ass and less tre le, more like a Polytone
right setting swaps the standard mam o tone control to a Fender AB763 circuit

•clean / harmonic ; 2 way switch
the clean setting is pure and clean, very high headroom
the harmonic setting is similar to a valve preamp, turning the guitar up and playing
harder will produce more dynamic overtones. Use the gain control and guitar volume
to get the est of this to suit your taste. High gain settings will produce mild overdrive
on loud notes.
•master volume
the main volume control
•rever depth
set the amount of rever
•rever time
set the rever time, ( room size / dwell )
•effects send ; 1/4" mono jack
line level output, taken efore the rever and master volume
can also e used as a line out
•effects return ; 1/4" mono jack
line level input
•direct out ; 3 pin male XLR
alanced output, taken after the rever is added, and efore the master volume control
The output level here is affected y the gain control, ut not affected y master volume.

guidance for first time users
•Plug in to the mains and switch on.; The green light will come on.
•Set the gain control and the bass, middle and treble controls to 12 O'clock.
•Set the master olume to zero.
•Plug your guitar into input A
•Turn your guitar olume up full.
•Play loudly and turn up the master olume to the required maximum loudness.
•Adjust the tone controls and re erb etc. to your taste
•Use the guitar olume to control the o erall loudness.
Some important points worth noting;
please read this first, if you need more info there is a user guide at www.mambo-amp.co.uk
and feel free to contact us for further advice if you need it.
n the harmonic setting it is possible to overdrive the preamp with high gain settings when playing loud. The intention is to
make the notes sound richer at lower le els and if you want to, you can get a soft o erdri e when playing loud at higher gain settings. If
you want a cleaner sound, turn the gain down, or use the clean setting. Be aware that at high le els the harmonic setting will be slightly
noisy. This is normal and is due to the al e-style harmonic circuitry. If you need really low noise turn the master olume down, or use
the clean setting.
Use the tone switch to select the best overall tone for your preference. This switch adds great tonal ersatility and co ers the
whole range of tones a ailable from Fender style amps, through to Polytone style amps. The centre setting is the classic Mambo sound.
The bright setting has a Fender style sound, the deep setting is more like a Polytone. Be aware that the Fender setting does ha e a
slightly higher noise le el. This is normal and is due to the Fender-style tone circuitry.
To use the headphone socket, turn the master volume control to zero. The loudspeaker is not automatically muted when you plug
the headphones in. This is to remo e the common problem of loudspeaker mute-switch failure.
There are two guitar inputs, input A is normal, input B has a dB pad, i.e. half gain. Use input A with most guitars. Some acti e
guitars and pedals may benefit from using the low gain input B. If plugging in two guitars at the same time both sockets automatically
switch to normal. i.e. they are identical if used simultaneously.
Extension loudspeaker the extension speaker socket is on the rear panel, the socket will accept standard 1/4" jack plug or "speakon"
connector ( when plugging in you need to rotate the plug until it locks) . make sure your extension loudspeaker is powerful enough, 200
watts minimum for 8 Ohms, 400 watts for 4 Ohms. Note 4 Ohm speaker should only be used with the internal speaker muted.
Mute Switch the mute switch on the rear panel switches off the internal speaker, use this if you want to use the amp with an external
loudspeaker cabinet of 4 Ohms impedance, or if you only want to hear the external speaker on it's own.
The power amplifier is rated for two 8 Ohm loads in parallel, e.g. 250 Watts rms, for the internal 8 Ohm speaker, plus an additional
250 Watts rms for an external 8 Ohm speaker. Be sure your external speaker is 8 Ohms or more, and can handle the power, 200 watts
minimum, You can use a 4 Ohm external speaker cabinet ONLY if the internal speaker is switched off.
Mambo amp electrical safety. Important please read carefully.
This amplifier is designed and manufactured in accordance with European electrical safety requirements for domestic appliances for use
indoors in a dry en ironment. Specifically the Low Voltage Directi e (LVD) 2006/95/EC
In order to continue the intended le el of safety, obser e sensible precautions and please note the following points;
•Use only with an earthed (3 pin) socket outlet. THIS UNIT MUST BE EARTHED.
•Do not use outdoors or in wet or damp en ironment.
•Protect from moisture, excessi e heat or physical damage.
•Switch off and unplug when not in use or when unattended.
•Select the correct operating oltage for your locality using the rotary switch near the power inlet on the rear panel.
•Always use the correct fuse.
There is a fuse fitted to the electrical inlet of the amplifier. Make sure the correct fuse is fitted. Ne er replace with a fuse with a higher
Amp rating.
Correct fuse ratings for the 500W rms mambo amp are;
4 Amp time-delay (T) fuse ( it's the same fuse type for US 115V and Europe 230V)
Mains power cable colour coding
The cable supplied uses European colour coding;
blue = neutral
brown = li e (aka hot or acti e)
green/yellow = earth. (aka ground)
The equi alent USA colour coding is Black = Li e White = Neutral Green = Earth
Australian colour coding is usually the same as European.
Use an RCD whene er possible to reduce the risk of electrical shock from musical instruments.
