M205 amplifier front controls

Amplifier Interface

There are two buttons on the front of the amplifier as well as three control features just under the front of the amplifier.

Display Modes| All display modes will be displayed at full brightness when a display status is changed and then fade to the brightness set by the user.

White
–  Power on.

Red
–  Power off.

Pulsing Amber
–  Standby (pressing the power button from this state will shut the amplifier off, pressing the standby again will turn it back on)

Flashing Red
–  Overheating Protection (Unit will not turn on until it has reached an acceptable temperature) Flashing Amber
–  Over-voltage protection.

---|---
Remote Trigger Switch| Normal
–  This sets the unit as the 12 volt trigger master.

No IR
–  Remote commands disabled.

Linked
–   This sets the powerbase as the 12 volt trigger slave. The ‘master’ unit will control this units power and standby with link cable installed.

Display Brightness| This is a rolling wheel to control the brightness of the power indication display
Delay switch| No Delay
–  The amplifier will have no delay before switching on.

Short Delay
–    The amplifier will have a short delay before switching on.

Long Delay
–    The amplifier will have a long delay before switching on.

Power

When plugging in power, the amplifier detects the input voltage and automatically switches between 120 or 240 volt operation. It is also available in a non-switching 100 volt permanent configuration.

Connecting to your Amplifier

Connect your analog interconnects to the amplifier and attach your speaker cables following the appropriate method below. MSB recommends to always unplug your amplifier when connecting or changing anything associated with your speaker lugs.

Each M205 is equipped with two sets of output lugs for easy setup or to be used in a dual connection bi-amp setup. Connect your speakers to the desired set of lugs.

Grounding Connections
On the back of each M205 there are chassis grounds available just below and to the inside of each set of output lugs. These grounding connections are labeled with a ground symbol. These are intended as a simple way to finish the grounding chain setup from an MSB Powerbase or to attach any shielded audio interconnect grounds. Never attach any ground wire to the negative terminal of the output lugs. Visit our website for more details.

Input impedance switch

To select the correct input impedance setting follow the table below.

(Lower impedance settings can be used, but contact your products manufacture first to ensure that a lower impedance setting will not damage the product)

M205 Amplifier Jack Panel

12 Volt Remote Trigger

This amplifier is equipped with a remote trigger for use with other MSB products. The trigger uses a 3 pin mini jack. When any MSB product is turned off, the other products connected will also turn off and viceversa. This trigger can also be used with other products. Products may use this trigger differently, so you may need to rewire a cable or use an interface relay. The connector is wired as shown. If you connect “signal” to “ground”, all MSB products will turn off. If you connect “signal” to “12 V” or leave it open, all MSB products will turn on. MSB amplifiers can also communicate standby when the ‘signal’ is pulled down using a 50K resistor. Use the power delay switch to stagger the powering on of the amplifiers. Visit our website for more details.

Technical Support

If you are experiencing any issues with your MSB product, please contact your nearest dealer or try our support page at www.msbtechnology.com/support. Please be sure you have the most current edition of your products firmware installed. If your issue persists please feel free to contact MSB directly.

MSB Return Procedure (RMA)

If a customer, dealer, or distributor has a problem with an MSB product, they should email tech support before sending anything back to the factory. MSB will do their best to respond within 24 hours. Should it be clear that a product must be returned, tech support should be informed and all the following relevant information should be provided:

input used, source material, system connections, and amplifier
4| Customer name
5| Customer shipping address
6| Customer phone number and email
7| Special return shipping instructions

MSB will issue an RMA number and create an invoice with all details outlined except the final price as the product has not yet been seen. This invoice will be emailed so all the above information can be checked and verified by the customer.

The product should be returned with the RMA number present on the box. Work can then begin immediately and the product can be sent back quickly.

Any repair that is difficult and cannot be completed in two weeks will be identified and the customer will be informed when it is to be expected. Otherwise the majority of repairs should be shipped back within two weeks if all the required information is present on the invoice.
