Speakon connectors offer quick connection for portable
applications. To enable a Speakon connection, plug the male
connector into the outlet and rotate it clockwise. It will then
lock into place and be ready for use.
The Appendices of this manual include a table to aid in the
selection of the appropriate cable gauge.
Connection to mains
Nominal AC voltage is 230V. Export versions may operate at
115 V AC. Nominal AC voltage will always be indicated on the
back panel.
For electrical safety, the amplifier uses an automatic power
switch that will switch off in the event of overloading or
overheating of the power supply.
Current draw
Can be seen on the accompanying table for 230V. Double the
ratings for 115V.
International safety agencies specify AC consumption using
pink noise at 1/8th of maximum power. This is done to
represent the current requirements to reproduce a typical
musical programme. The 1/3rd power rating represents a
worst-case scenario, while the maximum draw represents
consumption with sine wave signal, which will never occur in
practice.
Heat emission
Use the table below to predict the heat emission from your
amplifier, which can be useful to evaluate air conditioning
requirements. They are given in BTU (British Thermal Unit) and
calories.
USE
SWITCH ON/OFF
Switch your sound system on from back to front. Thus, switch
on the amplifiers last on your sound system. Switch sound
sources (CDs, turntables) first, then your mixer, then your
processors and crossovers and finally the amplifiers. If you
have more than one amplifier, switch them on sequentially,
one at a time or use a sequencer.
Follow the reverse order when switching off, and switch off
the amplifiers before any other element on your sound system.
CLIP LED
The clip LED should never be on continuously. This will distort
the signal and may damage the speakers. In fact, severe
clipping is an easy way of burning a speaker’s voice coil.
The amplifiers feature an automatic limiting system that
impedes prolonged saturation, but the dynamic nature of
music signals stops it from being a brick wall protection. Thus
at most, the clip light could be lit occasionally.
LEVEL CONTROLS
The
LEVEL rotary potentiometer is used for changing the input
gain. Although related to output
power, it is not a direct representation
of it. Thus, we can have maximum
output power with the gain at mid
position. Similarly, we may have the
gain controls at maximum and not
have maximum output if our source
signal is not hot enough.
One way to use the volume controls is
to set them such that when the
mixer’s faders are at their maximum
level, we are just below clipping level
on the amplifier or clipping very
occasionally.
