Models
The single channel Bose equalisation module (see
diagram on right) is compatible with the 36/50, 46/50, MPA626, Z4II, Z8II, CX-A450 & CX-A850; it is available in two
different models:
• Model 8 card for use with Bose model 8 speakers.
• Model 32 card for use with Bose model 25, 32 and 102
speakers.
There are two methods of mounting the Bose equalisation modules:
• Plastic snap-fit spacers for the 46/50, Z4II, Z8II CX-A450 and CX-A850
• Metal Hex Spacers for the 36/50 and MPA-626 amplifiers
Both types of spacer are supplied with the Bose equalisation modules.

Installation Information & Instructions
2a
36/50 Information
Each zone of the 36/50 can have a Bose equalisation module installed for use with Bose
100V line speakers. The relevant connectors marked Con 2-4 are to be found approximately
50mm from the rear of the chassis on the main PCB.
PCB Location of Bose Connectors and 65Hz Filter Jumpers
CON2 = Zone 1
CON3 = Zone 2
CON4 = Utility Zone
65Hz Jumper J5 = Zone 1
65Hz Jumper J8 = Zone 2
65Hz Jumper J9 = Utility Zone
When fitted with Bose 100V line speaker equalisation the respective zone must have its
65Hz filter switched ‘on’ (see section 2b).

36/50 Instructions
1. Switch off power and remove the mains lead.
2. Remove the top panel from the unit.
3. Remove the jumper from:
CON2 if you wish to connect the module to zone 1
CON3 if you wish to connect the module to zone 2
CON4 if you wish to connect the module to the utility output
4. Turn the relevant 65Hz filters ‘ON’ by moving the relevant jumpers (see notes above)
5. Next to the PCB connector there is an M3 screw through the PCB with a white arrow
pointing to it, locate this screw, remove it, retain it and replace it with the 12mm hex
spacer.
6. Push the Bose equalisation module onto the PCB connector; care must be taken to
position the module correctly always using the mounting spacer if only to verify the correct
orientation of the module.
7. Secure the Bose equalisation module to the spacer with the M3 screw (removed earlier).
8. Replace the top panel.

MPA-626 Information
PCB Location of CON 5
The connector for the Bose equalisation module is
marked as CON5 and can be found approximately
50mm from the rear of the variable line out control
on the main PCB (see diagram on the right).
When fitted with Bose 100V line speaker
equalisation the 70Hz filter must be switched ‘on’
(see section 2d)
Important note:
The existing MPA-626 can supply a total load of 54mA to external active devices and internal
modules. Care should be taken when using external active devices and internal modules
with the MPA-626 amplifier since exceeding the external load capacity risks the power
supply cutting out. The table below lists the current consumption of each compatible MPA626 external active device and internal module. Use this table to verify that the external load
of your proposed system falls within the specified limits.
External Active Device / Internal Module
AE-1
DM-1

Bose Equalisation Module
Current Consumption
9mA @ ±15V
18mA @ ±15V
7mA
If the 54mA load limit is exceeded the risk of temporary host unit failure will arise. If a failure
occurs switch off the amplifier and disconnect the internal modules and external devices, the
amplifier should be left off for approximately 30 seconds to allow it to reset. Check the wiring
and total current consumption of the internal modules and external active devices before
reconnecting the power and if the problem persists contact our technical department.

Z4II and Z8II Information

Each zone of the Z4II and Z8II mixers can have a Bose
equalisation module installed. The relevant connector can be
found towards the centre of each zone board marked CON 2
(see diagram on right).
Important note:
The power supplies of the Z4II and Z8II venue mixers have an
external load capacity of:
120mA for the Z4II and 190mA for the Z8II
Care should be taken when wiring or connecting internal

capacity risks temporary power supply failure. The table below lists the current consumption
of each internal module and external device compatible with the Z4II and Z8II. Use this table

If the mixer has a CPM paging microphone installed, you have the option to power the
microphone with the ‘CPM-PSU’ external power supply. This will reduce the load on the
system by 40mA.
If a power supply failure occurs switch off the mixer and disconnect the remote modules, the
mixer should be left off for approximately 30 seconds to allow it to reset. Check the wiring
and total current consumption of the external active devices before reconnecting the power
and if the problem persists contact our technical department.
