THE EXCLAMATION POINT WITHIN AN EQUILATERAL TRIANGLE, IS INTENDED TO ALERT THE

USER TO THE PRESENCE OF IMPORTANT OPERATING AND MAINTENANCE INSTRUCTIONS IN

1) Read these instructions.

2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this apparatus near water.

6) Clean only with dry cloth.

7) Do not block any ventilation openings. Install in accordance with the manufacturer’s

instructions.

8) Do not install near any heat sources such as radiators, heat registers, stoves, or other

apparatus (including ampliers) that produce heat.

9) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized

plug has two blades with one wider than the other. A grounding type plug has two blades

and a third grounding prong. The wide blade or the third prong are provided for your

safety. If the provided plug does not t into your outlet, consult an electrician for replace-

ment of the obsolete outlet.

10) Protect the power cord from being walked on or pinched particularly at plugs,

convenience receptacles, and the point where they exit from the apparatus.

11) Only use attachments/accessories specied by the manufacturer.

12) Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or

sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus

combination to avoid injury from tip-over.

13) Unplug this apparatus during lightning storms or when unused for long periods of

time.

INTRODUCTION

Double bass amplication gave the start to the Schertler company in the year 1986,

coming out with the rst non-piezo bass-pickup. Over the years, many products has

been added to the line, received by the double bassist community as helpers, that

changed the playing of this dicult to amplify instrument.

Just consequently, Schertler launches their double bass amp LaFaro, dedicated to one

of the best sounding bassist in the Jazz history.

Years of research, long experience in building acoustic ampliers and the decision to

create the best amp that would be technically possible gave rise to this compromise-

less completion of the double bass line.

Any source from pickups to mikes can be connected to the 2-channel Class-A preamp.

3 DI outputs, one for each channel and one in the master-section, an eect loop and

many more features in high end studio quality, guarantee for a never seen professional

versatility and quality, on stage as well as in a recording situations.

A traditional, transformer driven 280 Watts power amp moves a 8" woofer, specially

created for this amp with record-breaking long linear extension to furnish strong, clear

low frequencies and natural sounding mitts. A tweeter, powered with 80 Watts, takes

care to smooth and uncompressed harmonics, what is so important for any stringed

instrument, such as double bass.

The LaFaro also sounds great played with electric bass in rehearsals or recordings and

obviously it is a ne amp for Cello, when a strong amplication with fundament is

needed. Useless to mention the harmonic marriage with an acoustic bass guitar or

with a similar instrument.

This new amp is neither a light weight nor a cheap purchase. We simply believe, that

the LaFaro amp oers the most natural and musical amplication of the double bass,

particularly with our Schertler bass pickups STAT-B or DYN-B, and therefore it has been

thought to satisfy the professional player, weary of all the suered compromises.

1.5. 1.7. 1.6.

1.8.

1.1. MIC-IN

This microphone input is electronically balanced for XLR type connections. It has been optimized for

connecting microphones or other

transducers having low impedance and low level. The input is perfect for dynamic or condenser vocal

microphones.

1.2. PHASE

In case of feedback, or unwished eects between dierent channels use the phase reverse switch!

1.3. 48V

Phantom power supplies the XLR connector with 48V for powering condenser microphones.

1.4. GAIN

This variable gain preamplier adjusts the sensitivity level to ensure the best possible processing of

the signal through the channel.

It is important that this input level be set and optimised in the best way to achieve the cleanest sound

possible.

1.5. DRY OUT

signal can be sent to external systems, for example to another mixer. If you wish to record your music,

connect your recorder to the same output and start recording

1.6. HIGH, MID, LOW

These controls are devoted to high, mid and low frequency regulation. Oering cut and boost of +/-

15dB, they allow a wide range of tonal variations to be explored. When the controls are positioned

dentrally there is no cut or boost of the selected frequency band.

1.7. RESON

The Resonance (notch) lter cuts the frequency of 150Hz, to reduce low-frequency feedback.

- Left: no attenuation (at)

- Right: maximum

1.8. VOLUME

This rotary control regulates the channel volume.

2.7.

2.1. DYN-IN (Combo connector XLR or 1/4” Jack)

This input is electronically balanced for XLR type connections and unbalanced for jack type connec-

tions (1/4” - 6.3mm). It has been optimized for connecting microphones or other transducers having

low impedance and low level.

The 10V phantom power switch supplies the jack input and may be used for the electrostatic

condenser microphones with low sensitivity. This input is also designned for electrodynamic

microphones such as SCHERTLER DYN-Series transducers.

2.2. DRY OUT

Signal can be sent to external systems, for example to another mixer. If you wish to record your music,

connect your recorder to the same output and start recording

2.3. 10V

Phantom power supplies the jack connector with 10V for powering electret microphones and

Schertler Stat, basik and Lydia series.

2.4. GAIN

This variable gain preamplier adjusts the sensitivity level to ensure the best possible processing of

the signal through the channel.

It is important that this input level be set and optimised in the best way to achieve the cleanest sound

possible.

2.5. RESON

The Resonance (notch) lter cuts the frequency of 180Hz, to reduce low-frequency feedback.

- Left: no attenuation (at)

- Right: maximum attenuation

2.6. HIGH, MID, LOW

These controls are devoted to high, mid and low frequency regulation. Oering cut and boost of +/-

15dB, they allow a wide range of tonal variations to be explored. When the controls are positioned

dentrally there is no cut or boost of the selected frequency band.

2.7. WARM

When engaged, this low-pass lter damps higher frequencies to produce a warmer sound when using

bridge-mounted pickups such as Schertler STAT-series transducers for violin, cello and double bass.

4.8.

4.1. DI-OUT

General output. XLR balanced type connector for connections of external systems. The output volume

does not depend on the regulation of the MASTER-VOL but is eected by changes in individual channel

volume.

4.2. INSERT

This stereo jack plug enables the connnection of an external device (compressor, equalizer, etc.) in series

to all the outputs.

4.3. LINE-OUT

This unbalanced jack plug enables the connection of external systems. The output volume depends on

the regulation of the MASTER-VOL.

4.4. AUX-OUT

Additional output. This mono jack plug enables the connection to other systems. Output volume is

PRE-MASTER and POST-EFFECT (internal) REVERB, therefore this jack is independent from MASTER-VOL

potentiometer adjustments.

4.5. AUX-VOL

This rotary control sets the output level on the AUX OUT.

4.6. VOL LINE IN - EFFECT RETURN

This rotary control sets the input level on the LINE IN - EFFECT RETURN channel.

4.7. LINE IN - EFFECT RETURN

enables the connection of any external audio control eect. Use the LINE IN - EFFECT RETURN potentio-

meter to adjust the volume of the return channel.

4.8. MASTER-VOL

Controls overall system volume.

This switch changes the main power voltage from 230V~ to 120V~

5.2. GROUND LIFT

This switch connects and disconnects the ground between source and amplifier. Use this switch to suppress hum caused

by the power mains.

5.3. MAIN PWER CONNECTION

Connection to mains (230V~/120V~ - 50Hz/60Hz)

PLEASE ENSURE THE PROPER VOLTAGE AND USE THE ORIGINAL CONNECTION CABLE!

Fuse carrier: 120V~ - T4 A L 250 V (USA-JAPAN...) or 230V~ - T3.15 A L250 V
