SETUP PAGE
Max DA Out Level:
Range: 3 to 30dBu in 3dB steps
Max DA Out level should be set to match the Input level
sensitivity of the connected downstream device.
Max DA out can be set on individual output pairs.
DA Output 1-8:
Three options are available
- Balanced
Use this setting when connecting to common balanced
gear. This mode should NOT be used when connecting to
an unbalanced single ended Input and neither when
connecting to a connection with pin 2 (or 3) disconnected,
nor if pin 2 (or 3) is connected to pin 1.
Better sound quality is obtained using “Unbal Pin 2” or
“Unbal Pin 3” Output mode setting for this purpose.
- Unbal. pin 2 with signal on pin 2
Pin 3 must be connected to pin 1 either at the EQ Station
Output end or even better at the downstream device.
- Unbal. pin 3 with signal on pin 3
When using this mode pin 2 must NOT be connected.
This Output mode setting can be used though when
feeding a balanced Input.
Digital Output
Status Bits
For each pair of Outputs you can select between sending
AES or S/PDIF Status Bits.
Status bits - A few words:
S/PDIF and AES3 ("AES/EBU") interfaces are different
both regarding electrical level and the data format used.
With EQ Station you can choose the data format for each
Output pair, while the electrical interface is always high
level, balanced.
Advice for interfacing EQStation with S/PDIF equipment:
EQ Station Inputs accept S/PDIF as well as AES/EBU data
format. If an EQ Station Output feeds an S/PDIF Input,
choose S/PDIF format for that particular output.
A consumer S/PDIF Output with less than 5 m of cable
going to EQStation will most likely be able to pass a digital
signal, if you remember to tie pin 3 of the XLR to pin 1, and
use a good 75 ohm coax cable from the S/PDIF Output.
Going the other way, most S/PDIF Inputs are fine with
AES/EBU electrical level without resistor attenuation or
transformers. Don't use long cable runs, and again
remember to tie pin 3 of the AES/EBU Output to pin 1.
Clock Setup page
Source
Determines to which clock the EQ Station should attempt to
lock to:
Options are:
• Internal
• Word Clock
• Input 1-2
• Input 3-4
• Input 5-6
• Input 7-8
Rate
Sets the EQ Stations operating sample rate.
"44.1 kHz - only" or "48 kHz - only"
When 44.1 or 48 kHz is chosen the EQ Station should
ideally be fed with an external matching clock. However, if
e.g "44.1 - only" is selected and the external clock is 48
kHz the EQ Station will convert the sample rate and
operate at 44.1 kHz.
Wide
In Wide mode any incoming clock is accepted.
Error Handling
These options concern how the EQ Station should react
when a Clock Error or mismatch occurs.
Freewheel
Though there may be inconsistency between the set
internal clock rate and the rate present on the Inputs or
BNC - NO action is taken with regards to passing audio.
