6 Connections
Make sure the power switch is off before attempting
to make any input or output connections.
By using good quality input and speaker cables, the
likelihood of erratic signal behavior is reduced to a minimum.
Whether you make them or buy them, look for good
quality wires, connectors and soldering techniques.
6.1 Signal grounding
There is no ground switch or terminal on the Bias Q5
amplifiers. All shield terminals of input connections
are directly connected to the chassis. This means
that the unit’s signal grounding system is automatic.
In order to limit hum and/or interference entering
the signal path, use balanced input connections.
In the interests of safety, the unit MUST always
operate with electrical safety earth connected to the
chassis via the dedicated Protective Earth wire.
6.2 Analog audio input connections
Analog input is provided by means of Neutrik XLR female
connectors, one per channel input. Signal polarity of
analog input connections is shown in
Panel F, p. 6
.
6.3 Digital audio input connections
Digital input is supported via AES3 (AES/EBU).
AES3 connectors are Neutrik XLR female, one per channel
pair. The AES3 connection carries a channel pair through a
110
Ω nominal impedance wire in the form of a balanced
(differential) digital signal: in AES3 XLR connectors the
identification of hot and cold pins is not an issue; take
care to never tie pin 2 or pin 3 (balanced signals) to pin
1 (ground). Avoid the use of microphone cables in AES
connections: impedance mismatch can result in signal
reflections and jitter, causing bit errors at the receiver.
Ethernet cabling must comply to TIA/EIA-568-B and adopt
the T568B scheme pinout, as shown in Panel G, p. 6.
6.4 Output connections
CLASS3
WIRING
CLASS 3 WIRING
Output terminals are hazardous: wiring connection
to these terminals require installation by an instructed
person and the use of ready made leads. Take care to
secure the output terminals before switching the device on.
Single-ended and bridge-tied loudspeakers connection
are supported as shown in
Panel H, p. 7
.
6.5 Ethernet connections
Bias Q5 amplifier platforms can be remotely controlled
via an Ethernet connection through a personal computer
and Powersoft Armonía Pro Audio Suite software.
Void recommends the use of Ethernet Cat5 straight
through – patch – cables with pin/pair assignments TIA/
EIA-568-B, i.e. T568B, as shown in
Panel G, p. 6
.
