HOW TO RACK-MOUNT THE SUM EIGHT/SIXTEEN INTO THE RACK

1) Remove the SUM from its packaging

2) Turn off the rack and disconnect it from the mains

3) Remove the screws from the rack (two or four depending on which version of the SUM you

are using - see red circles on Pic. 1)

4) Touch the rack to eliminate electrostatic charges. They may damage the SUM

5) InserttheSUMintotherackmakingsureitperfectlyfitsthesocket(markedinyellowon

Pic. 1)

6) Drive the screws back in place (do not use too much force)

7) Properly connect the audio input and output of the slot. Reconnect your audio cables in

case you have removed them.

8) Plug the rack back into the mains.

9) Set the volume to 0 (anti-clockwise)

10) Turn on the rack

*Please note:

We used an API-500 B6 Lunchbox (main picture below) as an example for describing the mountingprocedure.However,accordingtoAPIʼs“VPRAlliance”standardizationprogramguidelines.

1) VOLUME The volume adjustment is made as follows:

The non-stepped rotary knob provides accurate gain increments of 1dB.

The gain range scale goes from -21dB to +9dB, when operating in mono mode.

For stereo channels, the reference gain range scale is -18 / +12dB (3dB more). For visual reference, both scales are represented on the front panel of the Sum Sixteen.

The gain control acts on both the main output and the headphone output.

STATUS SWITCH BUTTON MODE SYMBOL

OFF Stereo

2) MONO / STEREO BUTTON SWITCHES The SUM operates in mono or stereo, depending on the switch buttons status. (Pic. 4 and Pic. 5)

The eight audio channels available on the DB25 connector can be used in stereo mode (signals panned hard left or hard right) or in mono mode (signals panned center).

In thefirstcase,channelsarestereo-linked ingroupsof two(1-2),(3-4),(5-6),(7-8)and thespatialinformation of the original sound source is retained as well as its automation parameters.

In the second case, each channel is used independently for mono sources. This is generally very useful when dealing with those signals that are usually panned center in the mix like snare, kick, bass, lead vocals etc.

• Manufacturers like Mogami, Canare or Belden build cables of outstanding quality.(shielded, noise-free, star quad cables.)

• Cable connectors must be reliable and maintain their funcionality over long periods of time. Manufac-turers like Neutrik or Switchcraft are renowned for their products.

• Cables should not exceed a certain lenght and should not be damaged.

To connect the SUM you will need DB25 to XLR (or TRS) cables. (Pic. 10)

Attention: When connecting an balanced output to a subsequent audio device with an unbalanced input, the negative signal lead (from Pin 3) must be wired to shield (Sleeve) at the TS connector
