D1 Plus Bias Patch Panel
Wiring the Bias D1+/Q1+/Q1.5+/Q2+ Patch Panel
Void Acoustics’ Bias D1+/Q1+/Q1.5+/Q2+ uses a phoenix style connection for analog audio inputs and outputs. When in a touring environment where re-wiring an amplifier regularly may be needed, standard connections such as XLR and speakON are more desirable.
The Bias Patch Panel shown in Figure 1 allows for the desired connectivity of XLR and speakON while using a Bias D1+/Q1+/Q1.5+/Q2+ ampөмүрлүү.
The wires are pre-terminated with bootlace ferrules for easy set up.
The ground/shield wires for the Input signal connections have a green heat- shrink applied. This is a thicker wire than the green signal wire used for Ch3.
The following guide outlines how to wire the patch panel to the Bias+ amplifiers including the non-plus Bias versions.
Wiring for Bias D1+
The Bias Patch Panel can be used to work with two Bias D1+ ampаман калгандар.
The following method puts one amplifier on Inputs/Outputs 1+2 and another on Inputs/Outputs 3+4. If wiring for one amplifier, skip the steps referring to a second ampөмүрлүү.
Кирүү сигналы
The Bias D1+ has two inputs, therefore the third and fourth inputs on the patch panel can be used for a second D1+ ampөмүрлүү.
When wiring up a second Bias D1+ to the Bias Patch panel, the input phoenix is wired as in Figure 3.
Output Signal
There are two glands on the rear of the patch panel which have a 4×2.5mm cable. This cable is wired to the output phoenix connector. The labels on the cables will show 1+2/2 and 3+4/4.
If wiring two Bias D1+ amplifiers to the patch panel, wire both connectors as in Figure 4 with Ch3 in place of Ch1 and Ch4 in place of Ch2. 
When plugging the output phoenix block into the Bias D1+, it will be inverted screw side down and plugged into the Output Phoenix.
Wiring for Bias Q1+/Q1.5+/Q2+
Кирүү сигналы
The Gland on the right-hand side of the patch panel when looking at the rear, has 4 balanced cables within a multicore. The cables are individually labeled 1/A, 2/B, 3/C, 4/D. They are respectively Ch1, Ch2, Ch3, Ch4. They are wired as in Figure 5.
When plugging into the amplifier ensure that you are using the bottom Input Phoenix connection as highlighted in Figure 6.
Output Signal
There are two glands on the rear of the patch panel which each have a 4×2.5mm cable. This cable is wired to the output phoenix connector.
The labels on the cables will show 1+2/2 and 3+4/4. They are wired as in Figure 7. It is important to note the orientation of the phoenix block. 
When plugging the output phoenix block into the Bias Q1+/Q1.5+/ Q2+, it will be inverted screw side down and plugged into the Output Phoenix shown in Figure 8.
