Care of your amplifier will prolong it's life.....andLaney
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 amplifier.
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
BEFORE
SWITCHING ON
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 bass amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual play
testing, as well as burn in.
Laney
When you first recieve your 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.

ACTIVE and PASSIVE/ACTIVE inputs are
provided for connection of bass guitars. Active basses should be connected via the
ACTIVE socket. Non active basses should be connected using the passive input. Active
basses may also be placed in the PASSIVE 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 (8) to produce the desired signal
characteristics.
Engages and disengages the on-board COMPRESSOR. This
compresses the input-signal giving a punchier sound.
Controls the low-frequency response of the pre-amplifier.
Controls the high-frequency response of the pre-amplifier.
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 output-signal.
Send and return sockets are provided for connecting external effects-units.
Socket for connecting external tuner.

Limiter Defeat:
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.
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.
The LIMITER monitors both power-amp clipping and load so it automatically registers the
cabinet-impedance and sets itself accordingly.

Socket for providing a line-level-signal-source for connecting to an additional
external power-amplifier.
Both speakon-connectors and jack sockets are provided for the
connection of external cabinets. RICHTER bass-heads feature a single speakon-connector
and either one or two jack-sockets, depending on the model. Multiple cabinets can be
connected using either connection method. All Laney cabinets feature link out speakon and
jack sockets for connecting additional cabinets to Richter bass heads. CAUTION: the
minimum load that the MBH165 can be run at is 4 Ohms. A load of less that 4 Ohms will
cause the amplifier to operate below its recommended impedance. This should be avoided
as it may result in permanent damage.
