Introduction Thank you for purchasing a MAC-2. This product is designed to add MIDI capability to your guitar amplifier. With a MAC-2, you can use a MIDI footswitch to control your amplifier and all of your MIDIenabled effects, giving you the ability to switch amplifier channels and effects with the tap of a single button. The MAC-2 is designed to work with the full line of amplifiers by Diamond Amplification.
Front Panel Function buttons 1 through 5 – These buttons control the five switches found on the MAC-2. Once the MAC-2 is connected to an amplifier, these buttons will control the amplifier just like the amplifier’s footswitch does – switching channels, boosts, or any other feature found on the footswitch. These may also be used to control effect bypass, channel or function controls. Each function button has a blue LED next to it. When a function switch is on, its LED is lit.
Back Panel SW1, SW2, SW3 – These jacks are for switches 1, 2 and 3, controlled by Function buttons 1, 2 and 3 on the front panel. When a Function LED is lit on the front panel, the tip and ground of the corresponding jack are connected together. You may plug any standard ¼” mono cable here (like a guitar cable) and connect it to one of your amp’s switching jacks. SW4/5 – This jack is for switches 4 and 5, controlled by Function buttons 4 and 5 on the front panel.
your MIDI controller needs more than 800mA, an adapter with a higher current capacity is required. Power – This unit requires power supply in the range of 9 to 18 volts, AC or DC. The plug should be a 5.5mm/2.1mm barrel connector, similar to those used in most effects pedals. The MAC-2 requires a power supply able to deliver at least 200mA of current. This power is also passed directly to the MIDI In jack to phantom power the connected MIDI footswitch.
Programming Programming the MAC-2 lets it know which switches to turn on when you select a program number on your MIDI footswitch. For each program number on your footswitch, you can choose which channel and which features are active on your amplifier. For example, you can set up button 1 on your MIDI footswitch to select channel 2 on your amp, and button 2 on your MIDI footswitch to select channel 1 and the boost function. The MAC-2 is designed to work with any standard MIDI footswitch.
1. Plug a ¼” cable into Switch 1 on the MAC-2 and the jack for your channel switching on your amp. 2. Make sure your MAC-2 is connected to your MIDI controller with a MIDI cable. 3. Using your MIDI controller, step on preset 3. 4. Using the MAC-2 buttons, press Switch 1. The LED will light up and your amp will change channels. 5. Hold down the MAC-2’s write button until the MAC-2’s LEDs flash. 6.
your footswitch to control your amp’s boost function. Pressing that button will allow you to turn the boost on or off regardless of the current MIDI program number that has most recently been selected. The following Continuous Controllers are supported: Continuous Controller Value Function CC88 0..63 64…127 Switch 1 off Switch 1 on CC89 0..63 64…127 Switch 2 off Switch 2 on CC90 0..63 64…127 Switch 3 off Switch 3 on CC91 0..63 64…127 Switch 4 off Switch 4 on CC92 0..
Setup Mode Setup mode allows you to change how the MAC-2’s MIDI and switching functions work. In most circumstances, you won’t need these functions at all. If you have a complex MIDI setup, or an amplifier with special switching requirements, setup mode will help you integrate the MAC-2 into your rig. Setting MIDI Channel The MAC-2 responds to MIDI channel 1 by default. If you’d like to change it to respond to a different channel, you can follow these steps: 1. 2. 3.
Once you’ve chosen your MIDI channel, press the Write button. The MAC-2 will flash its LEDs, then return to normal operating mode with the new settings in effect. Setting Inverted Functions On certain amplifiers, a switching function is inverted. For example: your amp has footswitchable reverb. But, when you control it from the MAC-2, reverb is on when its function LED is not lit and reverb is off when its function LED is lit. If you find that this is happening, follow these steps: 1. 2. 3.
Now, press the buttons to select the function or functions that require momentary switching. Make sure that only the momentary functions are lit up and all others are not lit. Once you’ve done this, press the Write button. The MAC-2 will flash its LEDs, then return to normal operating mode. The functions you selected will now use momentary switching.
Data Backup To make sure your settings are never lost, you can copy your settings from one MAC-2 to another, or copy them from a MAC-2 to a computer. MAC-2 to MAC-2 copy To copy settings from one MAC-2 to another: 1. 2. 3. 4. 5. 6. Connect a MIDI cable to the MIDI Thru jack of the MAC-2 you wish to copy from. Connect the other end of the MIDI cable to the MIDI In jack of the MAC-2 you wish to copy to. Make sure that no other MIDI cables are connected to the MAC-2s. Make sure that both MAC-2s are on.
To copy your settings from the computer back to your MAC-2, connect the MAC-2’s MIDI In jack to the computer’s MIDI output. Make sure the MAC-2 is on. Using your SysEx program, load your settings and send them to the MAC-2. The MAC-2’s LEDs will flash briefly. Once this is done, disconnect power to the MAC-2, wait a second, then reconnect power. The MAC-2 will now be using its new settings.
