RoXdon TX-73 Studio Transformer (2 x Carnhill) Color Box + Analog VU Meters

The RoXdon TX-73 Transformer Color Box is designed to be connected to the balanced output of a studio mixer and with the 10dB front panel PAD switches engaged, provides the unique subtle coloration that the British Carnhill Transformers add to the audio and featured in classic audio equipment like the 1073 unit. This classic character can be heard on countless music recordings through the years and adds that final warmth and 'panache' to recordings.

The TX-73 features 2 channel (left & right) inputs & outputs via balanced wired TRS jack sockets. The meters are powered by an external International Power Supply therefore preventing interaction with the audio circuit. The Power Supply includes UK, EU, USA & Australian adapters. A convenient on-off power switch is also located on the rear panel.

The rear panel also features 600 ohm termination switches. The Carnhill output transformers used in the TX-73 are made for having an ideal load of 600 ohms. The input impedance of most modern amplifiers is 10K ohms or more. Engaging the 600 ohm switches, terminates the output of the transformers with a resister to bring down the load to about 600 ohms. The frequency response will change slightly so using these switches is a matter of choice. 
Also included is a tuned RC Zobel Network circuit to dampen high frequency transformer ringing.

Bypass switches are mounted on the rear panel which when engaged, bypass the transformers.

Supplied with input and output TRS jack to XLR link leads.

The meters are calibrated for the Pro Audio Level: 0VU = +4dBu (1.228V into a 600 ohm load).
