Mirror is a microphone/line level amplifier with all balanced sound path, with high headroom & overloading capacity at low noise floor.
|
 |
 |
|
The Mirror has a transformer-based balanced Low-Z mic/line input and balanced outputs. An exellent microphone input Cinemag or Jensen shielded transformers have an impeccable reputation acquired after many years of service.
|
 |
 |
|
The signal path is pure tube. There are no electrolytic capacitors - only high-ouality film capacitors. Electrolytic capacitors are only used in the power chain. The high quality passive components are used throughout.
|
 |
All audio chains are built with high-quality shielded oxygen-free wire.
|
 |
 |
|
As input attenuators is used high reliable ceramic switch with dual knife contacts covered by thick silver layer.
|
 |
 |
|
As a power transformer the Mirror uses either a toroidal transformer. In order to minimize power net noise and hum the preamp power circuit uses a stabilized DC voltage for plate and filament.
|
 |
 |
|
The rear panel houses 2 balanced Mic/Line XLR inputs, 2 balanced XLR outputs (or dualoutputs as extraoption), Ground/ Lift switches, IEC power socket, fuse.
|
 |
To eliminate ground loop hum the preamp assembly is completed with consideration for the topology of the given circuits. However there is a ground/lift switches on the rear panel, which connects or disconnects the ground pin of the output XLRs with the internal ground whenever necessary.
