User Instructions

NVA is different! No attempt is made to add output compensation networks, such as an inductor or parallel capacitor network or even fusing. Therefore, the amplifier is not unconditionally stable, and requires the use of our own 'LS Series' low capacitance speaker cable. Failure to adhere to these user instructions, or use of non-NVA speaker cable, will invalidate the NVA warranty.

Putting The System Together – Simple Method

1. Connect all interconnects and speaker cables

2. Lower the volume control(s) to minimum on pre-amp / integrated amp

3. Power the amp on from the switch on the rear panel

4. Check the selector switch is in the right position for your intended source, play some music and turn up the volume

If you hear a loud pop through the speakers at switch on, this is not a fault – no damage will occur to your amp or your speakers

Putting The System Together – Advanced Method

1. Lower the volume control(s) to minimum on pre-amp / integrated amp

2. Power on power amp(s) / integrated amp from the switch on the rear panel

3. Connect source interconnects to pre-amp / integrated amp input(s)

4. Connect pre-amp output interconnects to power amp(s) - ignore this step if using integrated amp

5. Connect speaker cables to speakers FIRST

6. Connect speaker cables to the amp starting with black

7. Check the selector switch is in the right position for your intended source, play some music and turn up the volume

Taking The System Apart – Simple Method

1. Lower the volume control(s) to minimum on pre-amp / integrated amp

2. Power the amp(s) off from the switch on the rear panel

3. Wait 5 minutes - essential

4. Disconnect all cables

Amps hold charge for a period of time after they have been switched off. The larger the amp transformers, the longer the charge is held. It is possible to damage the amp by crossing the speaker cables even if the amp has just been switched off!

Taking The System Apart – Advanced Method

1. Switch off music source

2. Lower the volume control(s) to minimum on pre-amp / integrated amp

3. Remove the speaker cable from the amp starting with the red

4. Disconnect the inputs

5. Power off the amp from the switch on the rear panel

Powering Off

NVA amps are made to be powered ON all the time; this is very safe and even the largest amps consume only around 3 watts when not playing music. If you decide you need to power down, switch off music source, make sure the volume is set to minimum then power the amp off from the switch on the rear panel.

Powering On

Switch off music source, lower the volume control(s) to minimum on pre-amp / integrated amp, then power the amp on from the switch on the rear panel.

Changing Inputs – Simple Method

1. Switch off music source

2. Lower the volume control(s) to minimum on pre-amp / integrated amp

3. Turn the amp(s) off from the switch on the rear panel

4. Wait 5 minutes

5. Change inputs

6. Power the amp up from the switch on the rear panel

NEVER unplug inputs while the amp is switched on and playing music

Changing Inputs – Advanced Method

Powering down of amp is NOT required but NEVER unplug inputs while the amp is playing music

1. Switch off music source

2. Lower the volume control(s) to minimum on pre-amp / integrated amp

3. Disconnect speaker cable from the amp starting with the red

4. Change inputs on integrated or pre amp

5. Reconnect speaker cables to amp starting with black

6. Check the selector switch is in the right position for your intended source, play some music and turn up the volume

NVA assumes that you as the owner will read, understand and heed the caveats regarding speaker wire and not short-circuiting the outputs, in order to obtain truly high-end performance at a fraction of its normal cost. Remember, the reward for intelligence is wonderful sound!
