SOLID STATE LOGIC Alpha Link MADI SX [13/32] Sample rate selection

Sample Rate Selection

The sample rate indicators show the current sample rate of the unit. When the

Alpha-Link clock source is set to ‘Internal’ (see opposite), pressing the SAMPLE

RATE button will step through each available sample rate (44.1kHz, 48kHz, 88.2kHz

and 96kHz) – as indicated by the corresponding LEDs.

When the clock source is set to an ‘external’ source (ADAT, AES/EBU, External or

MADI – the possible options depend on the particular Alpha-Link model) the

illuminated LED indicates the sample rate being received from that source. If there is an error

or if the received sample rate falls outside of the tolerance expected (±0.5% from nominal), all

sample rate LEDs will be off.

When locking to an ‘external’ source Alpha-Link will normally accept and lock to a wider clock

range at up to ±10% of the nominal rate, provided that the nominal rate corresponds to one

of the supported rates (44.1kHz, 48kHz, 88.2kHz and 96kHz). As noted above, if the sample rate from an external

source falls outside of the expected tolerance

all

sample rate LEDs will be extinguished although the clock source

LED should still indicate if a valid signal is being received.

If the unit has been set to interface the maximum 64 MADI channels (32 channels at higher sample rates), the

tighter clock tolerance of ±0.5% applies.

If the Alpha-Link is used in combination with a Mixpander card the SAMPLE RATE button will be deactivated and the

sample rate LEDs will reflect the clock source and sample rate settings made in the SSL Mixer software.

If pressing the Sample Rate button has no effect – and the unit is not connected to a Mixpander card – check

that the clock source is set to ‘Internal’.
