To prevent electric shock, do not operate the amplifier with any of the
conductor portion of the speaker wire exposed.
NOTE:
For reasons of safety and performance, use only high-quality fully in-
su lated speaker cables of stranded copper wire. Use the largest wire
size that is economically and physically practical, and make sure the
cables are no longer than necessary.
IMPORTANT:
When connecting speaker cabinets in parallel, always use all the con-
tacts in both SPEAKON
® connectors. If not, this may cause permanent
damage to the connectors and considerably reduce performance.
4.1 Controls
4.1.1 Volume Control
A microprocessor-controlled DCA (Digital Controlled Attenuator) with a
control resolution of 12 bits per channel is integrated into the signal path.
This means that the signal is not subject to an A/D followed by a D/A con-
version with associated losses and delay.
Using a DCA instead of the “conventional” VCA significantly reduces dis-
tortion and, at the same time, it improves the noise characteristics. A vol-
ume control with 41 notched settings controls the DCA via a microchip.
These settings have been selected to correspond to human hearing char-
acteristics and therefore guarantee an optimal range of settings for practi-
cal applications. Each channel can be set individually except when operat-
ing in mono modes whereby only channel A is active.
Set the volume to zero before turning on the amplifier to prevent the oc-
currence of sudden high volume levels which may cause damage to your
hearing and/or the speakers.
