Specially developed analog building blocks are 'coded' to emulate the behavior of a complex analog system. Unlike digital plug-ins or processor-based outboard gear, there is no latency, and no A/D or D/A conversions to compromise the sound. The result is a faithful recreation of the original response, without using the original analog hardware.

All of the important features of a two-track analog tape machine are found in the ATS-1, including speed selection, bias, LF record and HF Repro EQ, and the option of adding tape hiss, if desired. The reference 'record' level, as indicated on the illuminated VU meters, can be adjusted from 0 to +12 dBu in 3 dB increments.

The ATS-1 accurately models the behavior of specific tape machines and tape formulations, and allows the user to select from up to four machine and tape types. Optional machine and tape types are available on easy-to-install SIMM cards. Standard tape formulation cards shipped with the ATS-1 are the GP9 and 456. Standard machine cards are the A800 and M79.

RECORD
When the RECORD switch is depressed, the switch is illuminated and the ATS-1 tape simulation is activated.

STOP
When the STOP switch is depressed, the switch is illuminated and the ATS-1 is placed in hard bypass.

INPUT
The INPUT controls are continuously adjustable from minus 12dB to plus 18dB. Unity gain is at the center postion.

OUTPUT
The Output controls are continuously adjustable from minus 12dB to plus 18dB. Unity gain is at the center postion.

MACHINE TYPE
This rotary switch selects any one of four possible tape machine simulations, as determined by the SIMM cards installed in slots 1-4.

TAPE FORMULATION
This rotary switch selects any one of four possible tape simulations, as determined by the SIMM cards installed in slots A-D.

SPEED
This switch selects 7.5, 15 or 30 ips operation.

BIAS
The BIAS control sets the effective bias level in the record circuit. The center postion is the standard amount of overbias per tape formulation.

LF RECORD
The LF RECORD control adjusts the low frequency EQ in the record circuit. The center postion is standard alignment.

HF REPRO
The HF REPRO control adjusts the high frequency EQ in the playback circuit. The center postion is standard alignment.

REF. LEVEL
The reference level of the VU meter can be adjusted from 0 dB (+4dBu) to +12 dB in 3dB increments.

HISS
The hiss level can be set from off to way too much.
