amplifier.
8. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.
9. Never break off the ground pin on a power supply cord.
10. Power supply cords should always be handled carefully. Never walk or place equipment on power supply
cords. Periodically check cords for cuts or signs of stress, especially at the plug and the point where the
chord exits the unit.
11. The power supply cord should be unplugged when the unit is to be unused for long periods of time.
12. If this product is to be mounted in an equipment rack, rear support should be provided.
13. Metal parts can be cleaned with a damp cloth. The vinyl covering used on some units can be cleaned with
a damp cloth or ammonia based household cleaner if necessary. Disconnect the unit from the power
supply before cleaning.
14. Care should be taken so that objects do not fall and liquids are not spilled into the unit through any
ventilation holes or openings. On no account place drinks on the unit.
15. A qualified service technician should check the unit if:
The power cord has been damaged
Anything has fallen or spilled into the unit
The unit does not appear to operate correctly
The unit has been dropped or the enclosure damaged.
16. The user should not attempt to service the equipment. All service work is done by a qualified
service technician.
17. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary
considerably in susceptibility to noise induced hearing loss, but nearly everyone will lose some hearing if
exposed to sufficiently intense noise for a sufficient time. The U.S. Government's Occupational Safety and
Health Administration (OSHA) has specified the following permissible noise level exposure.
Duration Per Day In Hours Sound Level dBA, slow response
890
692
495
397
2 100
1 ½ 102
1 105
½ 110
¼ or less 115
According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear
plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in
order to prevent a permanent hearing loss if exposure exceeds the limits set forth above. To ensure against
potentially dangerous exposure to high sound pressure levels it is recommended that all persons exposed to
equipment capable of producing high sound pressure levels such as this amplification system be protected by
hearing protectors while this unit is in operation.

Care of your Laney amplifier will prolong it's life.....and yours!.
After unpacking your amplifier check that it is factory fitted with a three pin
'grounded' (or earthed) plug. Before plugging into the power supply ensure you are
connecting to a grounded earth outlet.
If you should wish to change the factory fitted plug yourself, ensure that the wiring
convention applicable to the country where the amplifier is to be used is strictly
conformed to. As an example in the United Kingdom the cable colour code for
connections are as follows.
EARTH OR GROUND - GREEN/YELLOW
NEUTRAL - BLUE
LIVE - BROWN
Congratulations on your decision to purchase a Laney amplifier.
Laney products are designed with ease of operation as a primary objective, however to
ensure you derive the best from your new amplifier, it is important you take time to
read this user manual and to familiarise yourself with the control functions and
facilities available.
INTRODUCTION
This manual has been written for easy access of information. The front and rear
panels of each unit are graphically illustrated, with each control and feature
numbered. For a description of the function of each control feature, simply check
the number with the explanations adjacent to each panel.
Your Laney RICHTER bass amplifier has undergone a thorough two stage, pre-delivery
inspection, involving actual play testing, as well as burn in.
When you first receive your Laney RICHTER bass amp, follow these simple procedures:
(i) Ensure that the amplifier is set at the correct voltage for the country it is to
be used in.
(ii) Connect your instrument with a high quality shielded instrument cable. Use of
cheap cables will compromise the sound of your instrument and your amplifier.

Normal and High inputs are provided for connection of bass
guitars. High output basses, either Active or Passive should
be connected via the High socket. Low output basses should be
connected using the normal input. High output basses may
also be placed in the Normal input if pre-amp overloading is
desired.
This control is used to set the level of gain present in the
pre-amp. The higher the level of gain, the more the signal
will clip producing distortion. The GAIN control should be
used in conjunction with the VOLUME control (10) to produce
the desired signal characteristics.
Engages and disengages the on-board cpmpressor. This
compresses the input-signal giving a punchier sound. In
association with the compressor are two LED s,one indicating
that the compressor is engaged and one indicating the
compressor is active. It is possible to have the compressor
engaged but it only be active during certian periods of
playing - typically the most dynamic sections. Note that the
higher the gain the greater the level of compression.
Controls the low-frequency response of the pre-amplifier.
The ENHANCE control provides an increased definition at the
low-end of the frequency spectrum giving you a tighter,
punchier sound. The ENHANCE control does this by providing a
dip in the frequency-response of the amplifier at
approximately 200hz. This dip eliminates some of the
secondary-harmonics of the important low-frequencies around
40-80 Hz producing a thicker sound. Turning the control
through to its maximum has the effect of boosting both the
low and high-frequency content of the signal whilst not
effecting the mids.

The 7-band onboard GRAPHIC-EQ allows extensive tonal-shaping
to be achieved. With the sliders along the centre-line the
GRAPHIC-EQ will exert a flat signal- response it is at this
point that individual frequency-bands can be cut or boosted.
Moving the slider beneath the centre-line will incur a
frequency-cut conversely, pushing the slider above the
centre-line facilitates frequency-boost. As a general rule,
avoid extreme settings of the sliders: try to set the
GRAPHIC with as little cut or boost as possible.
Controls the high-frequency response of the pre-amplifier.

possible to have the limiter engaged but not have the LED
active. The limiter monitors both power-amp clipping and
load so it automatically registers the cabinet-impedance and
sets itself accordingly.
Sets the overall listening level of the amplifier.
XLR socket for direct-injection of the amplifier signal to a
mixing-desk or additional power-amplifier. The XLR socket
provides a low-impedance balanced output-signal.
This socket(s) should be used to connect an extension-
cabinet. The impedance of the extension-cabinet must
not be less than 8 Ohms. Connecting cabinets that have a
lower impedance than 8 Ohms will result in the amplifier
overheating. Continual use in this manner may cause
permanent damage. Connecting a cabinet with an impedance of
greater than 8 Ohms will cause no damage to the amplifier but
will result in a reduced output.
Socket for connecting external tuner.
Send and return sockets are provided for connecting external
effects-units..

Normal and High inputs are provided for connection of bass
guitars. High output basses, either Active or Passive should
be connected via the High socket. Low output basses should be
connected using the normal input. High output basses may
also be placed in the Normal input if pre-amp overloading is
desired.
This control is used to set the level of gain present in the
pre-amp. The higher the level of gain, the more the signal
will clip producing distortion. The GAIN control should be
used in conjunction with the VOLUME control (12) to produce
the desired signal characteristics.
Engages and disengages the on-board compressor. This
compresses the input-signal giving a punchier sound. In
association with the compressor are two LED s,one indicating
that the compressor is engaged and one indicating the
compressor is active. It is possible to have the compressor
engaged but it only be active during certian periods of
playing - typically the most dynamic sections.
The ENHANCE control provides an increased definition at the
low-end of the frequency spectrum giving you a tighter,
punchier sound. The ENHANCE control does this by providing
a dip in the frequency-response of the amplifier at
approximately 200hz. This dip eliminates some of the
secondary-harmonics of the important low-frequencies around
40-80 Hz producing a thicker sound. Turning the control
through to its maximum has the effect of boosting both the
low and high-frequency content of the signal whilst not
effecting the mids.

Selects the LO MID-frequencies to be cut or boosted in
conjunction with the LO PARAMID LEVEL control (7). To
access low LO mid-frequencies turn the FREQUENCY control
anticlockwise, to access higher LO MID frequencies turn the
FREQUENCY control clockwise
Sets the level of boost or cut applied to the frequency set
by control 6. For frequency-boost turn the control
clockwise. For frequency-cut, turn the control anti-
clockwise
Hi Paramid Frequency : Selects the HI MID-frequencies to
be cut or boosted in conjunction with the Hi PARAMID LEVEL
control (9). To access low Hi mid-frequencies turn the
FREQUENCY control anticlockwise, to access higher Hi MID
frequencies turn the FREQUENCY control clockwise
Sets the level of boost or cut applied to the frequency set
by control 8. For frequency-boost turn the control
clockwise. For frequency-cut, turn the control anti-
clockwise
Controls the high-frequency response of the pre-amplifier.
Allows the on-board limiter to be defeated if desired. With
the switch in the out position the limiter is engaged. The
limiter is automatically triggered at high-output levels
and is designed to prevent power-amp distortion at high-
output levels. When the limiter is autpmatically triggered
an LED lights up to indicate the limiter is active. It is
possible to have the limiter engaged but not have the LED
active. The LIMITER monitors both power-amp clipping and
load so it automatically registers the cabinet-impedance and
sets itself accordingly.
Sets the overall listening level of the amplifier.
Switches the on-board horn either on or off.
