The Toner TAMM is a professional video modulator designed to fit most of the
industries popular 2RU chassis that hold up to 12 modules such as modula­tors, demodulators, and agile modulators. Some of the chassis that are com­patible are: Blonder Tongue MIRC, Drake RMM12, and Pico MPC-12, all
available from Toner.

The TAMM is a high quality vestigial sideband frequency agile audio/video
modulator for PAL television systems. The unit allows front panel channel
selection of standard off air broadcast and cable television channels up to
862 MHz by use of push button synthesized tuning.

The heterodyne conversion system, in conjunction with a SAW filter, ensures
optimum vestigial selectivity for adjacent channel operation.

The modulator is designed to accept any standard negative sync video at 1.0
Vp-p level. All controls are located on the front panel for ease of operation.
The modulator has a 3 digit LCD channel display with a lock - unlock function
to prevent unintentional channel changes. RF output level is 105 dBuV and
adjustable over a 15 dB range.

The Cable Television / Off-Air Band is selected with a front panel Cable /
Antenna switch, which can only be used when the unit is unlocked.

The modulator also features internal switches for audio pre-emphasis and
baseband audio or aural modulated carrier.
