3Introduction
!
Our Juicerack and JuiceBlock power supplies produce more current than any other 500 series
power unit on the market today. So you can be confident that any brand of 500 series module will be
powered correctly in your SM Pro Audio Juicerack / Juiceblock.
The power output (in milliamps) for each SM Pro Audio model is as follows:
Juicerack 1 = 600mA
Juicerack 3 & Juiceblock 3 = 320mA per module slot.
Juicerack 8 = 350mA per module slot.
The original API™ spec calls for an average of 130mA for each slot, but there are 500 series
modules from many manufacturers that require more power than that average. SM Pro Audio
ensures that you can easily power any 500 series module available today with our Juicerack and
Juiceblock power supplies.
!
3.1 Setup
!
SMPRO Audio JuiceRack and JuiceBlock power supplies feature all-metal construction and full
compatibility with the 500-series format. Unscrew and remove the face plate cover on your Juice
power supply with the provided allen key.
3.2 Mains Voltage
!
Juicerack 8 can be used with voltages ranging from 100V AC to 250V AC. Please make sure that
you have selected the correct voltage on the rear voltage switch before switching the unit ON. Any
damage occurring as a result of incorrect voltage selection may not be granted a warranty repair.
!
4Module Installation!
1.!!Please ensure there is no power connected to your Juicerack / Juiceblock.
2. Insert your 500 series module into your Juice power supply slot and push in until you
feel a click. The front panel of your module should be flush with the front panel of the
Juicerack 1.
3. Screw your 500 series module into the Juice power supply slot with the supplied screws.
4. Plug your source signal into the Juice power supply rear input. Use Input 1 for an XLR
balanced input or Input 2 for a 1/4“ balanced TRS input.
5. Connect the audio output of the Juice power supply into your audio mixer or amplifier
etc. The Juicerack 1 XLR output is a balanced output and the 1/4“ output is an
unbalanced output.

5Power up
!
1.!!Insert the external power supply into your Juicerack/block (or IEC cable for Juicerack8).
2. Push the power button on your Juice power supply.
3. If you are using a microphone pre-amp and a condensor microphone, push the phantom
power button.
6Juicerack 1
!
JuiceRack1 is a single-slot power source for operating one 500-series module. It is a half-rack
format, and includes a connector that allows two Juicerack 1’s to be mounted into a 1 ru 19” rack.
The external AC power supply design, keeps the power transformer separated from your 500
module’s sensitive electronics, and ensures reduced hum and signal interference.
7Juicerack 3 & Juiceblock3
Juicerack 3 and Juiceblock3 are 3 slot power supplies for your 500 series modules. The rear panel
includes balanced XLR inputs and outputs along with balanced TRS 1/4” inputs and unbalanced
outputs. A 48V phantom power switch is located on the rear. These 3 slot models include front
panel buttons allowing audio routing between modules without the need for manual cable patching.
7.1 Audio Routing:
• FEED - Sends the audio output of one module into the next module
• LINK1 - Split a single balanced input and sends it to multiple modules simultaneously
• LINK2 - Split a single unbalanced input and sends it to multiple modules simultaneously
Onboard LEDs indicate which modules are using the FEED / LINK features, with each slot’s status
independently configurable.

8Juicerack 8
!
JuiceRack 8 is a 19” rack-mount power source designed to house up to eight 500-series single slot
modules in a vertical configuration. The rear panel sports eight slots of balanced XLR inputs and
outputs along with eight slots of unbalanced 1/4” inputs and outputs.
A 48V phantom power switch is located on the front of the rack. When the +48V button is pushed,
the master phantom power is enabled, and each module may now enable its own phantom power.
8.1 Audio Routing:
• FEED - Sends the audio output of one module to the input of the next module
1. Press the select button until the feed LED is on
2. Press the status select button until 1-2 flashes twice
3. Press the ON/OFF button
4. The solid blue light shows output 1 is being fed into input 2.
5. Repeat the above process for feeding the other inputs.
6. NB: Inputs are fed in series.
Below is an example of how the feed button routes the audio
• LINK1 - Split a single balanced input and sends it to multiple modules simultaneously
1. Press the select button until Link1 LED is on
2. Press the status select button until the channel you wish to link is lit
3. Press the ON/OFF button
4. Repeat the above process to link further channels
Below is an example of how the LINK 1 button routes the audio
Input 1 is linked to inputs 2 & 3, whilst a separate input in module 6 is linked to inputs 7 & 8

SM Pro Audio Page 8 of 11 Juicerack / Juiceblock manual
!
•LINK2 - Split a single unbalanced input and sends it to multiple modules simultaneously
1. Press the select button until Link2 LED is on
2. Press the status select button until the channel you wish to link is lit
3. Press the ON/OFF button
4. Repeat the above process to link further channels
---------------------------------------------
Below is an example of more complex routing using FEED & LINK simultaneously.
Input of module 1 gets processed then outputs to (FEEDS) module 2, which again gets processed.
The signal then flows (LINKS) through to module 6 (with NO processing from inputs 3, 4 & 5) then
gets processed in module 6 and outputs to (FEEDS) module 7. (got that?)

9Removal of Modules
!
The Juicerack 1 and Juicerack 3 have small slots in the top of the chassis that allows the removal of
modules. After unscrewing the module, this is done using a small straight head screwdriver, which
can be inserted into the top slot and pushed forward to release the module.
In the Juicerack 8 the lid of the chassis can be unscrewed & completely removed for easy removal
of modules.
