25-Seven Program Delay Manager
Version 2.3 Manual April 2013 17
Lower speed numbers cause the least amount of tempo change, and are usually imper-
ceptible. But they take longer to fill the delay memory, or to return to real-time.
Higher speed numbers fill the memory more quickly, but might cause a noticeable
speed change on fast-paced material. The highest numbers might also cause occasional
doubling of fast consonants or drumbeats while the system is building a delay.

The Input Level Meter monitors the signal going in to PDM’s processing circuit. At least
one of its LEDs should be flashing whenever there’s audio at any reasonable level. More
details on this meter appear below.
The Cursor buttons let you navigate around the LCD display. In this manual, they’re
shown as

The
BYPASS
button is used for emergencies or when you want to take PDM out of the
signal chain

. It connects PDM’s analog and digital inputs to its outputs, with no proc-
essing or delay. It also clears PDM’s delay memory.
PDM automatically goes into electrical bypass, connecting its XLR inputs to its match-
ing outputs, when power is removed. Analog inputs are passed to their respective ana-
log output; AES/EBU input is passed directly to the AES/EBU output. This is totally
passive and no level adjustment or analog/digital conversion takes place.

Occasionally, you may need to do software updates or other system-level maintenance (page 55). Put
the unit in Bypass mode, or remove it from the signal chain, before beginning these operations.
