1. Introduction
The XLogic Channel ADC card is a small PCB assembly containing a high quality 24-bit stereo ADC.
The card is intended to be fitted inside the XLogic Channel unit to provide immediate A to D
conversion at any of the common sample rates between 44.1kHz and 192kHz. The ADC can be
synchronised either to internal crystal or an external word clock or AES/SPDIF sync source. Digital
output from the card is provided in both balanced AES and un-balanced SPDIF formats.
Because the XLogic Channel unit is a mono unit, a second balanced line-level input to the ADC card is
provided. This allows connection of, for example, a second XLogic Channel unit to enable full use of
the AES/SPDIF stereo data stream.
The object of this manual is to provide purchasers of the XLogic Channel ADC card with information
in the following areas:
• Safety considerations
• Installation instructions
• Operational instructions
• Connector pin-outs
• Specifications and physical dimensions
Please Note
The XLogic Channel ADC card is a hardware upgrade for the XLogic Channel unit – it must be
installed before it can be used. Full instructions to achieve this are provided within this
document, however, if you are unsure about performing this please contact your local Solid State
Logic distributor who will be happy to arrange to install it for you. Do note that a charge may be
levied for this service.
Warranty
The warranty period for this card is 12 months from date of purchase.
In Warranty Repairs
In the event of a fault during the warranty period the unit must be returned to your local distributor
who will arrange for it to be shipped to Solid State Logic for repair. All units should be shipped to Solid
State Logic in their original packaging. Solid State Logic can not be held responsible for any damage
caused by shipping units in other packaging. In such cases Solid State Logic will return the unit in a
suitable box, which you will be charged for. Please do not send manuals, power leads or any other
cables - Solid State Logic can not guarantee to return them to you. Please also note that warranty
returns will only be accepted as such if accompanied by a copy of the receipt or other proof of purchase.
Out of Warranty Repairs
In the event of a fault after the warranty period has expired, return the unit in its original packaging to
your local Solid State Logic distributor for shipment to Solid State Logic. You will be charged for the
time spent on the repair (at Solid State Logic's current repair rate) plus the cost of parts and shipping.

3. Installation
This section details how to install the XLogic Channel ADC card in an XLogic Channel unit. Before you
begin, please consider these points:
• Carefully read through these instructions first.
• Check that all of the component parts of the kit are present.
• Check that you have the required tools to hand before attempting installation.
• Consider if you need to adjust the operating level of the card. There are two options, set by an
internal jumper:
+24dBu (position ‘1-2’) 0dBu ≈ –24dB FS (SMPTE standard and factory default)
+18dBu (position ‘2-3’) 0dBu ≈ –18dB FS (EBU standard)

Tools Required
Other than any tools which may be required to remove the XLogic Channel unit from any racking or
studio furniture, the following tool is all that is required to install this card:
Qty Part No. Description Notes
1 80C2CECC 1-point pozi-drive screwdriver This is not a ‘philips’ screwdriver!
Do however, please note the following:
• The geometry of ‘philips’ and ‘pozi-drive’ screws and screwdrivers are
subtly different and so the two types of screw and screwdriver are not
inter-changable. It is however normally quite simple to differentiate
between the two types of screwdriver as the tip of a ‘pozi-drive’
screwdriver is quite blunt and has additional ‘flutes’ between each of the
four blades that make up the head, as shown in the illustration to the
right – a ‘philips’ screwdriver will be missing the flutes and has a much
sharper tip.
• Most ‘pozi-drive’ screws have an echo of the additional ‘flutes’ marked
on the head of the screw - take a look at the illustrations opposite and the
screws that we have supplied.
• The tip of any screwdriver should firmly locate in the screwhead – if it
does not then it is either the wrong type, the wrong size or worn out.
• If you neither possess nor can obtain a 1-point pozi-drive screwdriver
locally, it should be possible to obtain one from your local Solid State
Logic distributor.

Procedure
Remove the XLogic Channel unit from any racking or studio furniture, and place it on a suitable clean,
flat work surface. Ensure that the work area is adequately illuminated and then proceed as follows:
1. Using a 1-point pozi-drive screwdriver, remove the 15 M3 x 6mm csk screws which secure the top
cover to the unit. Lift the cover off and place it safely to one side.
2. Turn the unit around and using the same screwdriver, remove the two M3 x 6mm panhead screws
which fix the ADC blanking plate to the rear of the unit. The blank plate, screws and washers
removed can be discarded although it is recommended that they be retained in case it is found
necessary to remove the ADC card at a later date.

3. Remove the ADC card from its sealed anti-static bag, either fold back or remove and place to one
side the short ribbon cable attached to PL5. Slide the ADC card through the apperture in the rear
of the XLogic unit that was revealed in step 2. above. It may be necessary to lift the ‘OUTPUT’ and
‘Gnd’ (S1) cables on the main PCB to avoid them snagging under the ADC card.
4. The ADC card is retained in the XLogic unit by a total of six screws; two for the rear plate and four
for the PCB. Loosely fit four M3 x 6mm panhead screws and fibre washers in the PCB holes,
followed by two M3 x 6mm panhead screws and wave washers to the rear panel.

5. Check that the rear plate of the ADC card is flush to the rear panel of the XLogic unit and tighten
the six screws; these screws need only be lightly tightened – the ADC card isn’t going to be
escaping out of the box by itself…
6. Connect the short ribbon cable removed in step 3. above between PL5 on the ADC card and PL5
on the main PCB. Be sure to push these connectors fully home; they have about 5mm of travel and
there should be a light ‘click’ as they are seated.
7. Check that link LK1 on the ADC card is set to the correct position – if in doubt, leave it at the
factory (+24dBu) setting.
8. Refit the top cover to the XLogic unit and replace the 15 M3 x 6mm Csk screws – we have supplied
a few replacements if any were damaged (or missing). Like the ADC card, these screws should not
be over-tightened - they should be little more than finger tight. When the top cover is fitted, the
test and warning labels should all be visible - if they are not, you have put it on upside down!
9. Before refitting the XLogic unit to any racking or studio furniture it would be prudent to check it
for correct operation – Section 4. of this document details the operational features of the ADC card.

4. Operation
On the rear panel of the ADC card are four sockets and one multi-position DIP switch. Their functions
are as follows:
The front panel of the XLogic Channel unit carries no controls associated
with the ADC card although it does have a ‘Lock’ indicator, located
immediately below the ‘Power’ indicator. The various states of this
indicator are as follows:
State Function
Off The ADC card is not locked.
Yellow The ADC card is set to internal sync.
Red The ADC card is set to external sync and is locked.
Synchronisation
There are four possible synchronisation options, selected with switches 1 to 3 as follows:
Function Switch(es) Detail
Internal sync In this mode, with switch 1 ‘off’ (down), the ADC card will free-
run at the sample rate determined by the setting of switches 4 to
6 (see over leaf).
AES sync With switches 1 and 3 set this way, an external un-balanced
(75Ω) AES sync source may be used – switches 4 to 6 will need
to be set to match the nominal rate being applied.
Word Clock In this mode the ADC card will lock to an external TTL level
word clock at any nominal sample rate between 44.1kHz and
192kHz – again, set switches 4 to 6 to match the nominal rate
being applied.
‘Super Clock’ With switches 1 to 3 all set ‘on’ (up), the card will synchronise to
a 256x ‘Super Clock’ as provided from ProTools™ – switches 4
to 6 should be set to match the nominal rate being used (sample
rates greater than 96kHz are not supported).

Sample Rates
There are eight possible preset sample rate options ranging between 44.1kHz and 192kHz. The
different rates are selected with switches 4 to 6 as follows:
Sample Rate Switch(es) Detail
44.1kHz With all three switches ‘off’ (down), this sets the ADC to run at
44.1kHz stereo. For external sync at this rate, the applied AES or
Word Clock sync should be 44.1kHz whilst ‘Super Clock’ should
be 11.2896MHz.
48kHz This sets the ADC to run at 48kHz stereo. For external sync at
this rate, the applied AES or Word Clock sync should be 48kHz
whilst ‘Super Clock’ should be 12.2880MHz.
88.2kHz This sets the ADC to run at 88.2kHz stereo. For external sync at
this rate, the applied AES or Word Clock sync should be
88.2kHz whilst ‘Super Clock’ should be 22.5792MHz.
96kHz This sets the ADC to run at 96kHz stereo. For external sync at
this rate, the applied AES or Word Clock sync should be 96kHz
whilst ‘Super Clock’ should be 24.5760MHz.
176.4kHz This sets the ADC to run at 176.4kHz stereo. For external sync at
this rate, the applied AES or Word Clock sync should be
176.4kHz – ‘Super Clock’ is not supported.
192kHz This sets the ADC to run at 192kHz stereo. For external sync at
this rate, the applied AES or Word Clock sync should be 192kHz
– ‘Super Clock’ is not supported.
176.4kHz mono This sets the ADC to run at 176.4kHz in mono or ‘two wire’
mode. In this mode only a single channel of data is available and
so the second analogue input is not available. For external sync
at this rate, the applied AES sync should be 88.2kHz or Word
Clock at 176.4kHz – ‘Super Clock’ is not supported.
192kHz mono With all three switches ‘on’ (up), this sets the ADC to run at
192kHz in mono or ‘two wire’ mode. In this mode only a single
channel of data is available and so the second analogue input is
not available. For external sync at this rate, the applied AES sync
should be 96kHz or Word Clock at 192kHz – ‘Super Clock’ is not
supported.

Notes
• The external analogue input is DC coupled and electronically balanced. It will feed the right hand
side of the A to D converter in all of the ‘stereo’ AES modes – when the ADC card is set to run at
either 176.4kHz mono or 192kHz mono this input can not be used.
• The AES/EBU and SPDIF digital outputs are independant of each other. They are both transformer
isolated.
• The Sync Input is a 75Ω BNC and will accept either TTL wordclock (≈5V pk-pk) or unbalanced 75Ω
AES/EBU (≈1V pk-pk). Conversion from balanced to un-balanced AES/EBU is best achieved with
a third-party in-line transformer. These are widely available – your local Solid State Logic
distributor should be able to supply these. Alternatively, a standard 110Ω balanced feed can be
used, albeit at the expense of increased jitter due to the level/impedance mis-match.
• The ‘Lock’ indicator shows that the ADC card is locked to the selected sync source. Whilst this also
implies that the correct sample rate has been selected on the DIP switches on the rear of the unit,
it does not necessarily mean that valid AES/EBU data is being produced.
