Preamp out or Line out to my voice recorder

[Nampallil]

I want to record an audio live performance. My AHUJA TZA 7000 amplifier has
1. Pre out - 2mV/600 Ohm
2. Line out 1V/ 2Kilo Ohm


My ZOOM H1 voice recorder has line/mic in
Input impedance: 2k? (Input level: 0 to -39dBm)

Please advice how to record from the amplifier. From preamp out or line out to line in of the recorder or any other method.

Thanks in advance
