Control Section
24-26. Channel Selection switches
Selection switches with LED indicators to show
channel selected.
27. Store Switch Stores incoming MIDI information for channel selection
when used in conjunction with external MIDI device. (See
operational note B).
Operational Note B: MIDI Control
The MIDI section of your Anniversary amplifier is really very simple to
use. It allows you to control your amp’s channel switching (1,2 or 3)
via MIDI program change messages. The Anniversary amp has an
internal memory and can store Channel 1,2 or 3 selection in 128 MIDI
addressable patches. These correspond to the 0 - 127 MIDI
PROGRAM CHANGE message.
Note: The Anniversary amp is preset to receive MIDI messages on MIDI
CHANNEL 1 only.
On pressing the store button, the amplifier channel selection will be
stored in the PATCH number that was LAST received. If no patch message has been received then no store will be
made. Try this example;
A. Send MIDI PROGRAM CHANGE to Anniversary amp (for example 24) B. Select ampchannel (for example 2) C.
Press store until all three channel LED’S flash momentarily. Now, whenever the Anniversary amp receives MIDI
PROGRAM number 24, it will automatically select Channel 2. The memory will be retained when the amp is switched off.
Note: The internal memory of your Anniversary unit can be reset (all patches Channel 1) by holding down the channel
1 button and the store button during switch on. Be sure you really want to reset the memory first!
Note: Ensure that compatible MIDI cables are used.
Master Output
28. Effects Control
Gives control of the balance between effected and dry
signal when using external processors (see operational
note F).
29. Presence Control Boosts the upper frequencies to give extra crispness to
the amplifiers output. Operates on low damp settings of
power amp only.
30. Low Volume Compensation Switch
When the master volume is kept low, high gain valve
amplifiers can sound fizzy and unnatural. This switch
filters out the unwanted “fizz”, adds bottom and has
great benefits for recording and rehearsal. The
effectiveness of this control decreases as the master
volume is increased.
31. Master Volume Controls the overall volume level of the amplifier.
32. Standby Switch In the off position the valve heaters remain on,
ready for instant use without the signal circuit being
active. With the standby switch off no sound will be
produced from the pre-amp or power stage.
33. Power Switch On/Off switch for mains power to the amplifier.
