User’s Manual
Introduction
Dear customer,
Thank you for choosing the EBS BZ1/PU2 Bouzouki amplification package.
The products are manufactured in England to the highest standards using high quality materials. They have been designed and
tested to be reliable, long lasting state of the art products with a sound for the Bouzouki that is second to none.
Quality
The BZ1 is equipped with top quality materials. Some examples are: Gold plated jack sockets for long life, professional XLR
balanced outputs for hum free sound, non polarized electrolytic capacitors for higher quality sound, polystyrene capacitors for
EQ filtering. This results in a quality sound for years to come.
The PU2 Pickup is built to the same high quality standards as the BZ1. The PU2 has a specialized amplifier on board that has huge
power capability and high quality sound.
The pickup coil is precision wound around a powerful ceramic magnet and then potted in resin for a low distortion crystal clear
sound.
Testing
Our BZ1/PU2 Bouzouki amplification package is the result of many hours of listening tests, live tests at concerts and night clubs,
with some of the finest Bouzouki soloists.
We would like to thank all the Bouzouki soloists who tested our prototypes, giving us their suggestions and comments, and
helping to make the BZ1/PU2 a reality that is now available to our customers.
Thank you very much.

BZ-1 Bouzouki Preamplifier
BZ-1 Front Panel
Input Section:
1. Input Jack: Use a Mono Jack lead to plug in your EBS PU2 pickup. If using a wireless system, be sure to set its output level
so that it is no higher than the PU2’s output level. Boosting the output level of your pickup will cause the BZ1 to overload!
2. MUTE: Press the Mute switch in to Mute the Signal at the Input Jack – this allows you to easily plug and unplug your
instrument while avoiding on/off noises and without the need to turn your volume down.
3. Signal LED: The signal Light (LED) flashes Green when you start to play, to indicate that there is a signal at the input of the BZ1. When the
Mute switch is pressed the light shines Red to indicate that the input is muted.
4. Style: The Style switch gives the option of 2 playing styles. In the IN position the sound is Legato with a softer sound that
has more sustain. In the OUT position the sound is staccato with a more natural acoustic dynamic sound. You might prefer
different settings for different venues. For example, when doing a sound check in an empty room the sound is more hard and
brittle and you might prefer legato to soften the sound but once the gig begins and the room is full of people the room
acoustics will change and soften the sound, in which case you might prefer staccato. If unsure, we recommend staccato as this is the most
natural sound.
5. 5 Band EQ:
The BZ1 when used with the PU2 and a good quality monitor will sound superb with all 5 bands of the EQ
set to flat (centre position).
If for example your monitor lacks smoothness and is thin and bright in the Treble, you can cut a little
Treble and boost a little HMF to make the High frequencies smooth and mellow.
If you prefer a more smooth mellow sound that is easy on the fingers, you can boost MF and HMF to
make your sound more round and powerful.
If your monitor sound is dull and bloated in the Bass, you can boost Bass a little and cut LMF a little to
clean the low frequencies up.
If you monitor has a small light Bass sound, you can Boost Bass and LMF to give it more body.

User’s Manual
Reverb Section:
6. Reverb: We recommend you start at the centre position. For a cleaner drier sound just cut Reverb and for a softer richer
sound boost Reverb.
7. Decay Time: We recommend starting with the Decay Time button pressed IN; this gives a nice balanced sound that is easy to play and is
suited to most playing styles. With the Decay Time in the OUT position you have a shorter decay time which gives an ultra clean sound that is
ideal for purists that play with little or no Reverb.
8. Large: The Large button, when pressed IN, overrides the Decay button and gives a large sounding reverb with a very long Decay Time. This
is ideal for players that like a big dynamic sound with a long Reverb tail. We recommend starting with the Large button in the OUT position as
this suits most playing styles.
9. Volume: This controls your Monitor volume and does not affect the volume of the Lineout. Lineout volume is controlled by
the PA console/mixing desk that it is plugged into.
Power Section:
10. ON Indicator: When the BZ1 is powered on the Indicator (LED) will shine Green.
11. Power: This is the On/Off switch that Powers the BZ1 on and off. Always power ON the BZ1 before powering on your Monitor
to avoid switch on noises coming through the monitor. Also for the same reason, always power off your monitor before powering
off the BZ1. Additionally when powering the BZ1 On or Off, always mute the appropriate channel on the PA console/mixing desk that the
Lineout is connected to.
Please ensure the BZ1 is switched off and unplugged from the mains electricity supply before being moved.

User’s Manual
12. Mains Input: The BZ1 is provided with a detachable power lead that connects here. The specific mains input voltage rating
that your BZ1 has been built for is clearly marked on the back panel below the mains input. Before connecting for the first time,
please ensure that your BZ1 is compatible with your electricity supply. If you have any doubts, please get advice from a qualified
person.
13. Output: Fully balanced output for connecting to a powered speaker or a power amplifier driving a passive speaker. This
output serves as the main output since it includes all the BZ-1 sections including level changes made from the volume control. This
output can be considered as the “Bouzouki Player’s Output”
The effects loop should be used in the instance where the bouzouki player has the need to use an external, higher quality
reverberation processor. When an external processor is connected, the BZ-1 Reverb level control should be turned to zero so
the internal Reverb gets deactivated. The sound of the external processor will be routed to the “Stage Monitor” and “Output”
XLR line outputs. Changes made to the external processor will affect the overall sound of the BZ-1 preamplifier and the ratio
between the “dry” bouzouki sound and the reverb amount will be controlled through the “MIX” parameter of the external reverb processor.
The cables used should be unbalanced (TS) Jack lead cables, same type used for instruments.
14. Effects Return: Accepts the output of an external effects processor.
15. Effects Send: Sends the signal to the input of an external effects processor.
16. Stage Monitor Lineout: Fully balanced output for connection to an external PA console/mixing desk. This lineout sends
the full sound with the EQ and Reverb sound to the mixing console, so be sure to set the PA console/mixing desk channel with all
EQ flat or bypassed and any console/mixing desk effects set to zero. The stage monitor lineout will pass through all the EQ and
reverb changes made by the player but not the volume changes. This will ensure that changes in level made by the bouzouki
player will not affect the “Mix” in the other band members monitor zones. Volume changes made by the bouzouki player will affect just his
personal mix.
17. Front of House Lineout DI: This Output is only for use by a sound engineer who requires a DI output for Front of house
sound. This DI output sends the character of the BZ1 sound but bypasses all EQ, Reverb and Volume settings on the BZ1. So any
setting changed on the BZ1 will not affect this Lineout and the front of house sound.
